Table of Contents
What Are Organic Photovoltaics?
Organic photovoltaics (OPVs) are a type of solar cells that use organic molecules or polymers to convert sunlight into electricity. Unlike traditional solar cells, which are made of inorganic materials like silicon, OPVs rely on organic materials that can be processed into thin films, allowing for flexible, lightweight, and potentially cheaper solar energy solutions. OPVs cell absorbing layer is based or organic semiconductors (OSC)- typically either polymers or small molecules.
How Do Organic Photovoltaics Work?
The basic principle behind OPVs is similar to that of traditional solar cells: they absorb light and convert it into electrical energy. However, OPVs use organic compounds, which are carbon-based, instead of silicon. These organic materials are typically semi-conductive polymers or small molecules that can absorb light and generate charge carriers (electrons and holes).
When light strikes the organic materials, electrons are excited and separated from their atoms. The movement of these free electrons generates an electrical current that can be harnessed to power electronic devices or charge batteries. The efficiency of OPVs largely depends on the quality of the materials used and the design of the solar cell.
The Steps that Govern OPV working can be summarised as:
They are flexible cells with versatile applications making it easy to integrate them with other products
They allow for new marketing opportunities due to their design features such as flexibility, low weight, etc.
There is an abundance of manufacturing materials which keeps prices lower
Lower manufacturing costs compared to current solar technology
Lower purchase cost due to lower manufacturing costs
Organic photovoltaic cells can be produced continuously using printing tools, allowing for efficient production
Lower environmental impact when manufactured
Short energy payback times

In organic photovoltaic (OPV) cells, light absorption generates electron-hole pairs in the active layer, which produces electrical current. The materials are designed for strong absorption in specific light wavelengths to maximize energy conversion. Factors like chemical structure, molecular weight, and material orientation affect absorption. Conjugated polymers, such as polythiophenes and polyfluorenes, improve light absorption, including in the near-infrared range.
The active layer’s morphology, typically a blend of electron-donor and electron-acceptor materials, is crucial for efficient charge separation. Strategies like light-trapping structures and plasmonic nanoparticles (e.g., gold or silver) further enhance absorption by increasing light path length or concentrating electromagnetic fields. Researchers continue to explore new materials and techniques to improve OPV cell efficiency.
2. Charge separation
In organic photovoltaic (OPV) cells, electron-hole pairs are separated by a built-in electric field created by the energy difference between the donor and acceptor materials in the active layer. This charge separation is crucial for generating current. The donor material (e.g., conjugated polymers) donates electrons, while the acceptor material (e.g., fullerene or non-fullerene acceptors) accepts electrons. When light is absorbed, an exciton forms, which then dissociates into free charges at the donor-acceptor interface, enabling charge collection at the electrodes.
The active layer’s morphology must ensure good contact between donor and acceptor materials for efficient charge separation. Optimizing the morphology and aligning the energy levels of donor and acceptor materials are key for efficient charge separation. Researchers are also exploring alternative acceptor materials and tandem structures to enhance OPV cell efficiency.
3. Charge collection
In organic photovoltaic (OPV) cells, separated electrons and holes are collected by electrodes, typically made of transparent conductive materials like indium tin oxide (ITO), aluminum, or silver. Charge collection is crucial for generating current and depends on the efficient transport of charges to their respective electrodes. The efficiency of this process is influenced by factors such as the active layer’s morphology, the mobility of charge carriers, and the alignment of energy levels between the donor and acceptor materials. Proper charge collection is essential for the overall performance of the OPV cell.
4. Electrical output
The electrical output of an OPV cell depends on charge separation and collection processes. Key factors that determine its efficiency include short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF), and power conversion efficiency (PCE). These metrics are crucial for evaluating the overall performance of the device. For more details on their impact on efficiency.
Device structure of OPV cells
1. Single-layered OPV cells
Single-layer OPV cells consist of a single organic material layer where donor and acceptor materials are mixed. They have simpler architecture and lower production costs but typically offer lower efficiency. When light hits the donor-acceptor layer, electron-hole pairs are generated and separated by the built-in electric field. The separated charges are collected by electrodes to produce an electrical current. The cell includes a transparent electrode (usually indium tin oxide or zinc oxide) as the anode, a donor-acceptor blend layer, and a metal electrode (often aluminum or silver) as the cathode.
2. Bilayer OPV cells
Bilayer OPVs consist of two organic semiconductor layers: an electron-donating (p-type) layer and an electron-accepting (n-type) layer, sandwiched between two electrodes. The donor layer is typically a conjugated polymer or small molecule, and the acceptor layer is often a fullerene derivative or non-fullerene acceptor. When light hits the bilayer, it generates an exciton in the donor layer, which is separated into an electron and hole. These charges are transported through the respective layers, creating a photocurrent used to generate electricity.
3. Bulk heterojunction OPV cells
Bulk heterojunction OPV cells consist of an interpenetrating network of electron-donating and electron-accepting materials, typically conjugated polymers or small molecules. These materials are blended and deposited on a substrate. The blend allows efficient charge separation and transport. The anode, made of a transparent conductive oxide, and the cathode, made of metal, sandwich the active layer. When light hits the cell, it creates an exciton in the donor material, which separates into an electron and hole. These charges are transported to the respective electrodes, generating a photocurrent to produce electricity.
4. Tandem OPV cells
A tandem PV cell consists of multiple sub-cells connected in series to improve efficiency. Each sub-cell uses different materials with varying band gaps to absorb different parts of the solar spectrum. The absorber material generates electron-hole pairs (excitons), while the electron transport material separates and transports the charges. The first sub-cell absorbs high-energy photons, and the second absorbs low-energy ones. This design allows tandem PV cells to capture a wider range of the solar spectrum, improving overall efficiency.

This technology has taken solar panel efficiency to a new level, making it a popular choice for residential, commercial, and industrial applications. In this comprehensive guide, we’ll explore everything you need to know about PERC solar panel, including how they work, their benefits, types, and key considerations for installation.
Table of Contents
What are PERC Solar Panels?
More efficiently than traditional solar panels, PERC solar panels use Passivated Emitter and Rear Contact (PERC) solar cells to transform sunlight into electricity. Traditional solar cells are improved using PERC (Passivated Emitter and Rear Cell) technology, which increases their capacity to absorb and transform sunlight. The additional layer on the cell’s rear, which reflects sunlight that would otherwise be lost, is the primary distinction between PERC solar panels and traditional panels.
How Do PERC Solar Panels Work?
PERC panels work by optimizing the rear side of each solar cell:
Additional Passivation Layer: PERC cells feature a passivation layer on the back, which enhances light capture. This layer reduces recombination losses, where electrons and holes cancel out each other before generating electricity.
Reflective Surface: The passivation layer acts as a mirror, bouncing sunlight back into the cell. This design ensures that sunlight that might have escaped is redirected into the cell for energy conversion.
The innovation behind PERC solar panel offers several advantages:
1. Higher Efficiency
PERC panels are about 1% more efficient than traditional panels, and can be up to 3% more efficient in low light and high heat. This can increase energy production for a PV system by up to 5%.
2. Increased Low-light and High-heat Performance
PERC solar panels excel particularly well in both high-heat environments and low-light environments, with about a 3% increase in efficiency.
3. Enhanced Temperature Tolerance
PERC panels are more resilient in high-temperature conditions, ensuring optimal energy production even during warmer months.
4. Space Efficiency
With their higher efficiency, fewer PERC solar panels are needed to achieve the same energy output, which can save on space and installation costs.
5. Smaller Roof Footprint
Because PERC panels are more efficient, solar designers and installers need fewer of them to create the same power as traditional panels. This means a solar panel system using PERC panels can fit onto smaller roofs.
6. Greater Power Density
Due to their higher efficiency, PERC panels generate more power per square foot, allowing users to produce the same amount of electricity with fewer panels. This can reduce the footprint required for installation, making them ideal for areas with limited space, such as rooftops or urban installations.
7. Proven technology
PERC technology is a modification of standard cells, so there’s reduced risk for financiers.
Types of PERC Solar Panels
There are two primary types of PERC solar panel:
1. Mono PERC Solar Panels
Monocrystalline cells with an additional reflecting layer, known as mono PERC solar cells, increase efficiency by reabsorbing light that isn’t initially caught. By applying a dielectric passivation film to the rear surface of the cell, this technology—known as a Passivated Emitter and Rear Cell, or PERC—allows the cell to absorb both direct and dispersed light. Due to the increased efficiency and space-saving high energy density of monochromatic PERC panels, there is a great deal of research and development being done to improve this technology on a global scale.
2. Poly PERC Solar Panels
In India, polycrystalline solar cells are widely used since they are reasonably priced and qualify for government subsidies. India’s plentiful sunshine reduces the impact on energy generation, even though their efficiency is marginally lower than that of Mono PERC panels. Only polycrystalline cells now satisfy the Domestic Content Requirement (DCR), which requires the use of Indian-made cells for installations looking to get government subsidies because they are produced domestically rather than imported.
3. Bifacial PERC Solar Panels
These panels capture sunlight from both the front and the back, increasing total energy production. They use a double-glass structure or a transparent back sheet. High-efficiency panels can generate up to 25% more energy compared to single-sided panels, especially in high-reflectivity environments like sand or snow.
4. Dual Glass PERC Solar Panels
Dual glass or double-glass panels use two layers of glass to encase the solar cells instead of the traditional glass-and-backsheet design. Dual glass panels with PERC technology have similar efficiency to other PERC panels but offer greater durability and a longer lifespan.
PERC vs. Traditional Solar Panels
