FAQs

The solar energy industry has witnessed remarkable advancements in photovoltaic (PV) technology over the years. One of the most promising innovations is Tunnel Oxide Passivated Contact (TOPCon) technology. This cutting-edge technology is revolutionizing the efficiency and performance of solar cells, making them a preferred choice for residential, commercial, and industrial applications.

TOPCon solar cells are an evolution of the widely used Passivated Emitter and Rear Contact (PERC) technology. With superior passivation and improved electron flow, TOPCon technology enhances energy conversion efficiency while reducing losses, positioning itself as the next-generation PV technology.

In this comprehensive guide, we will explore TOPCon technology, its benefits, working principles, comparison with other technologies, market trends, and future prospects.

What is TOPCon Technology?

TOPCon, short for Tunnel Oxide Passivated Contact, is an advanced solar cell architecture that enhances efficiency and energy yield over conventional solar cells. As the name suggests, TOPCon cells use a thin, passivating tunnel oxide layer that enables excellent carrier selectivity and low contact resistance, allowing more sunlight to be converted into electricity.

In simple terms, TOPCon technology combines the best benefits of older cell technologies like PERC (Passivated Emitter and Rear Cell) and heterojunction cells into one single architecture while avoiding their drawbacks. As a result, TOPCon delivers superior efficiency of over 22%, compared to around 18–19% for PERC cells currently.

Key Features of TOPCon Technology:

1. Tunnel Oxide Layer: The tunnel oxide layer in TOPCon (Tunnel Oxide Passivated Contact) solar cells is a thin layer of silicon oxide that passivates the silicon surface. This layer is a key component of the cell’s structure, which improves efficiency and performance. 

2. Poly-Silicon Contact: Poly-silicon contact TOPCon technology, or Tunnel Oxide Passivated Contact technology, is a solar cell technology that uses a polycrystalline silicon layer to improve the efficiency of solar cells.

3. Higher Efficiency: TOPCon panels can achieve efficiency rates of over 22%, which is higher than traditional solar cells. 

4. Superior Passivation: Superior passivation TOPCon technology is a solar cell technology that uses a thin layer of silicon dioxide to improve the performance and efficiency of solar cells.

5. Bifacial Benefits: Bifacial solar panels with TOPCon technology are more efficient than traditional solar panels and can generate more electricity. They are especially useful in areas with low sunlight, such as cloudy days or areas with vegetation. 

How TOPCon Technology Works

TOPCon (Tunnel Oxide Passivated Contact) technology is an advanced solar cell architecture designed to enhance the efficiency and performance of photovoltaic systems. It achieves this by incorporating a thin tunnel oxide layer and a polycrystalline silicon layer to form a passivated contact on the rear side of the cell.

How do TOPCon solar cells work?

Tunnel Oxide Passivated Contact, or TOPCon for short, refers to a certain solar cell construction. Even after researchers at Freiburg’s Fraunhofer Institute for Solar Energy Systems introduced the new cell architecture in , it took several years for the first TOPCon modules to be sold.

The fundamental tenet of the TOPCon concept is that the silicon layer is not in contact with the metal of the connection contacts. Charge carrier recombination, which usually results in performance losses at the back of the cell, is avoided as a result.

A thin layer of silicon oxide (a few nanometers thick) is applied to the solar cell’s surface to prevent recombination. This layer passivates the surface, meaning it prevents a certain kind of charge carrier from passing through, but it is so thin that the current can “tunnel through” it quantum mechanically. In addition to this “tunnel layer,” a layer of highly doped silicon is added to increase electrical conductivity and lower transmission losses.

Benefits of TOPCon Technology

1. Higher Efficiency Levels

The mass production efficiency of TOPCon has reached up to 25.2%, surpassing the mainstream PERC’s 23.2% by 2 percentage points. Projections indicate that TOPCon’s efficiency could soar to 26.8% by the second half of , widening the efficiency gap with PERC to 3.3 percentage points.

2. Low Degradation Rate

The N-type battery’s wafer substrate, doped with phosphorus, nearly eliminates photoluminescence attenuation due to the absence of boron-oxygen pairs. The first-year attenuation rate of TOPCon modules is about 1%, compared to PERC’s 2%, with an average annual attenuation rate post-first year of about 0.4% (vs. PERC’s 0.45%).

3. Low Temperature Coefficient

TOPCon modules excel in high-temperature environments, with a power temperature coefficient as low as -0.30%/°C, compared to PERC modules’ -0.34%/°C.

4. High Bifacial Rate

The bifacial rate of TOPCon can reach over 80%, significantly higher than PERC’s 70%. This attribute is particularly advantageous in large base projects with high ground reflectivity, enhancing power generation efficiency.

5. Environmental Impact

Investing in TOPCon solar panels contributes to a cleaner environment by reducing dependence on fossil fuels. Solar energy is renewable and produces no greenhouse gas emissions during operation. By choosing TOPCon technology, you are not only saving on energy costs but also making a positive impact on the planet.

6. Installation and Maintenance

The installation process for TOPCon solar panels is similar to traditional solar panels. It typically involves mounting the panels on your roof or in your yard, connecting them to an inverter, and integrating them with your home’s electrical system. Regular maintenance is minimal, usually requiring only occasional cleaning to ensure optimal performance.
