Topcon (Tunnel Oxide Passivated Contact) solar cells represent a significant leap in solar photovoltaic (PV) technology. Topcon is essentially a new generation of monocrystalline silicon solar cells designed to reduce efficiency losses and improve energy output. This is achieved through a passivation layer that reduces recombination losses, one of the main factors causing energy loss in traditional cells.

One variety of n-type solar cells is the TOPCon cell. A semiconductor material that has been doped with phosphorus to give it a negative charge is used to create n-type cells. Higher efficiency and improved performance in low light levels are only two of this type of cell’s many advantages over p-type cells.

Introduction to Bifacial Solar Panels

Standard solar panels consist of three layers: a top layer of transparent glass that protects the panel and allows sunlight to pass through, a middle layer of silicon that converts solar energy into electricity, and a bottom aluminum frame for support. Bifacial panels differ by replacing the aluminum frame with an additional layer of glass, enabling them to capture reflected light from the ground. You can visualize bifacial panels like an ice cream sandwich, with glass layers on the outside and silicon in the center. They are typically installed to face the sun on one side while the other side collects reflected light.

    As solar energy technology evolves, innovative solutions emerge to enhance efficiency, durability, and cost-effectiveness. One such breakthrough is Topcon solar panels technology, a major advancement in the photovoltaic (PV) industry. In this comprehensive guide, we will explore the intricate details of TOPCon solar technology, its benefits, how it compares to traditional solar panels, and the potential it holds for the renewable energy landscape.

    What is TOPCon Solar Panel Technology?

    TOPCon (Tunnel Oxide Passivated Contact) is an advanced solar cell technology known for its high efficiency. It features a tunnel oxide layer between a transparent conductive oxide (TCO) layer and a p-doped crystalline silicon layer. The TCO layer allows sunlight to pass through, while the p-doped silicon absorbs and converts solar energy into electricity. The tunnel oxide layer reduces charge carrier recombination at the surface, enhancing the solar cell’s efficiency and energy capture.

    TOPCon technology revolves around the idea of minimizing electron loss by utilizing tunnel oxide passivation, a method that allows solar cells to retain more of the energy generated during sunlight exposure. As a result, TOPCon panels deliver higher performance under various environmental conditions.

    How Does TOPCon Technology Work?

    At the core of TOPCon technology lies its n-type silicon substrate and a thin oxide layer known as the tunnel oxide layer. The tunnel oxide acts as a passivating agent that prevents recombination of charge carriers, thus reducing energy loss. This structure is topped with a layer of polycrystalline silicon, which further boosts the panel’s ability to retain electrons and enhance efficiency.

    The key working mechanism of TOPCon technology includes:

    Tunnel oxide layer: The tunnel oxide passivated contact (TOPCon) approach is an alternative to classical heterojunction solar cells enabling efficiencies of up to 24.4%. The tunnel oxide is a core element of this contact as it has to reduce the minority carrier recombination but simultaneously must not hamper the majority carrier flow

    Polycrystalline silicon contact: Polycrystalline solar panels consist of photovoltaic cells with silicon crystals that act as semiconductors. When exposed to sunlight, the silicon absorbs energy and releases electrons, generating an electric current. This electricity is collected by metal contacts and sent to an inverter, where it is converted for building use, producing clean, renewable energy.

    N-type silicon base: N-type silicon, a semiconductor material, has advantages over p-type silicon, such as reduced light-induced degradation and better temperature coefficients, leading to improved performance. TOPCon technology uses a thin silicon oxide layer to reduce carrier recombination, boosting efficiency. When combined with N-type silicon, TOPCon cells can achieve up to 28.7% efficiency, surpassing PERC cells at 24.5%. TOPCon is compatible with existing PERC production, offering cost-effective manufacturing and higher efficiency, and is expected to become the mainstream cell technology.

    The Development and Evolution of TOPCon Technology

    The development of TOPCon solar panel technology (Tunnel Oxide Passivated Contact) marks a critical point in the evolution of solar cell technology, building on years of advancements aimed at improving solar panel efficiency and reducing production costs. Understanding the history and evolution of TOPCon provides insight into how this technology has become one of the leading innovations in the photovoltaic (PV) industry.

    1. Early Innovations in Solar Technology

    The history of solar energy dates back to the 7th century B.C. when people used magnifying glasses to harness the Sun’s power. Over time, civilizations like ancient Greece and Rome utilized solar energy for heating. A major breakthrough came in 1839 when Edmond Becquerel discovered the photovoltaic effect, leading to the development of solar cells.

    In 1954, Bell Labs created the first practical silicon solar cell, sparking rapid advancements in solar technology. By the 1970s, the energy crisis fueled interest in solar power, leading to cost reductions and increased accessibility.

    Key milestones include the use of solar panels in space with Vanguard I in 1958 and the creation of the first solar-powered aircraft in 1981. The 2000s saw innovations like thin-film solar cells and bifacial panels, while modern advancements in efficiency continue to push the limits of solar technology. In 2021, 168 GW of new solar capacity was installed globally, highlighting the rapid growth of solar energy.

    2. Emergence of PERC Technology as a Precursor

    Solar cell efficiency plays a crucial role in reducing the cost of solar power generation. Over the past five years, cell efficiency has improved by about 0.3% annually. Monocrystalline cell efficiency increased from 18% in 2010 to 19.5% in 2015, while multicrystalline cells rose from 16.5% to 18%. These gains were achieved mainly through front-side optimizations.

    However, the industry has now shifted focus to the rear side of the cell, introducing PERC (Passivated Emitter and Rear Cell) technology. PERC adds a dielectric passivation layer to the rear of the cell, reducing recombination losses and improving efficiency beyond the limitations of traditional Back Surface Field (BSF) cells. This relatively simple modification enhances performance without altering the front side of the cell and is easily integrated into existing production processes.

    3. The Birth of TOPCon Technology

    In 2013, researchers from Fraunhofer Institute for Solar Energy Systems (ISE) in Germany first proposed the concept of TOPCon (Tunnel Oxide Passivated Contact) technology. The goal was to further reduce electron recombination losses that were limiting the performance of existing solar cells. TOPCon introduced the idea of using a thin tunnel oxide layer to passivate the silicon surface of the solar cell, combined with a layer of doped polysilicon for better charge carrier transport.

    The key innovation in TOPCon technology is the use of the tunnel oxide layer, which acts as an ultra-thin barrier between the silicon wafer and the polysilicon contact. This oxide layer is only a few nanometers thick but plays a crucial role in preventing unwanted recombination of charge carriers, allowing more electrons to flow freely through the cell, increasing the efficiency.

    4. Advancements in TOPCon Efficiency

    Since its initial proposal, TOPCon technology has undergone several stages of refinement. Early prototypes of TOPCon cells demonstrated promising results, with efficiency rates above 23%, but the challenge was in scaling up production for commercial use.

    By 2018, leading solar manufacturers like LONGi Solar and JinkoSolar began to explore the commercial potential of TOPCon cells. These companies invested heavily in research and development to optimize the production process, increase efficiency, and reduce costs. Over the next few years, advancements in materials science and manufacturing techniques allowed for the commercial production of TOPCon cells with efficiencies exceeding 24%.

    5. TOPCon Technology vs. PERC and Other Solar Cell Technologies

    A TOPCon solar cell looks visually the same in a module as a PERC solar cell does once it is mounted. But unlike PERC cells, TOPCon cells are composed of more difficult-to-manufacture n-doped silicon. Still, TOPCon cells are able to reach better efficiency levels thanks to this substance.

    An additional noteworthy distinction is that TOPCon cells require a more time-consuming passivation procedure. Although this technique is more difficult technically, the result is greater. In particular, adding a layer of polycrystalline silicon to the cell’s backside can tolerate greater voltages, which increases the solar cell’s overall efficiency, but it also necessitates a large amount of technological work.

    1. Efficiency

    PERC Solar Cells: Typically achieve efficiency rates between 20% to 22%. The passivation layer helps in capturing more light and converting it into electricity.

    Topcon Solar Cells: Can reach efficiency rates above 28%. The advanced passivation and tunneling oxide layers contribute to these high-efficiency levels.

    2. Cost

    PERC Solar Cells: Generally, PERC cells are more affordable than Topcon cells. They offer a good balance between cost and performance, making them popular among solar panel manufacturers.

    Topcon Solar Cells: While more expensive, Topcon cells provide higher efficiency and longer lifespan, which can justify the higher initial investment.

    3. Applications

    PERC Solar Cells: Ideal for residential and commercial installations where cost-effectiveness is a priority. They are also well-suited for regions with lower light conditions.

    Topcon Solar Cells: Best for high-performance applications, including large-scale solar farms and installations in high-temperature regions

    6. Challenges in TOPCon Development

    Despite its potential, the development of TOPCon technology has not been without challenges. One of the primary hurdles has been the complexity of the manufacturing process. Creating the ultra-thin tunnel oxide layer with precision and ensuring uniformity across large solar cell wafers is technically demanding and requires advanced equipment.

    Additionally, the initial costs of producing TOPCon cells were higher than conventional PERC cells, making it difficult for some manufacturers to justify the transition. However, as research continued and production techniques improved, the costs associated with TOPCon manufacturing have gradually decreased, making the technology more commercially viable.
