TOPCON SOLAR CELL MARKET OVERVIEW

Global TOPCon solar cell market size was estimated at USD 13.51 billion in 2024, set to expand to USD 83.89 billion by 2033, growing at a CAGR of 22.49% during the forecast period.

The photovoltaic cell is known as a TOPCon (tunnel oxide). Solar cell is a further development of solar cell technology. TOPCon solar cells have gained attention in recent years for their ability to outperform conventional solar cell designs in terms of efficiency and effectiveness. There is a growing need in the market for highly efficient solar panels, e.g TOPCon cells due to the demand for renewable energy sources and the goal of maximizing the energy production of solar systems. The idea behind Tunnel oxide passive contact (TOPCon) technology is that the metal component cannot get close to the wafer.  TOPCon technology refers to N-type cells.

TOPCon's N-type silicon substrate is covered with an ultra-thin tunnel oxide film, followed later by an additional layer of highly doped polysilicon that bonds the metal at the edges. Silicon wafers are used in the manufacture of P- and N-type solar cells. The difference between N-type and P-type comes from the substance used to dope the silicon wafer, which is done to increase the power. Phosphorus has the advantage over boron that oxygen cannot decompose phosphorus, but boron can. In addition, phosphorus doping increases efficiency by bringing free electrons to the wafer. Cell and module efficiency is higher for TOPCon cells than P-type cells because they absorb more sunlight.

COVID-19 IMPACT

COVID-19 reduced manufacturing hence hindered market growth

The COVID-19 pandemic has been unprecedented and staggering, with the TOPCon solar cell market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

COVID-19 has seriously affected the global economy and had a devastating impact on global business, affecting households, businesses, financial institutions, industrial companies and infrastructure companies at the same time. The new coronavirus has affected several economies and caused a shutdown in many countries, which has limited market growth. The shutdown of industrial producers has led to a decrease in demand for solar-related equipment in most countries of the world. The decline in electricity use in industrial plants worldwide during the pandemic will have a negative impact on market development.

LATEST TRENDS

Technical advances in next-generation solar cells leading market expansion

There are different generations of solar cells according to development. The first generation solar cells include solar cells based on crystalline silicon material. Second-generation solar cells are thin-film solar cells, which are the main focus of this report. It contains the materials cadmium telluride, amorphous silicon, copper indium gallium selenide and gallium arsenide. Third generation solar cells are new on the market; some of them are not yet on the market. Third-generation solar cells in organic solar cells, dye-sensitized solar cells, and perovskite solar cells are covered in other sections. Technological advances, such as the development of Thin-Film technology, make it possible to create more efficient, cost-effective and durable solar cells using less material. For example, in June 2022, researchers found Princeton University has developed the first commercially viable perovskite solar cells that can be produced at room temperature and require less energy to produce than any other solar cell, such as silicon-based solar cells.

DRIVING FACTORS

Growing demand for solar cells with higher efficiency and flexible manufacturing processes augment the market growth

TOPCon solar cells are an attractive choice when organizations are looking for alternative technologies to solar cells with lower production costs, simpler operations and better efficiency prospects. The growing demand for solar cells with higher efficiency and flexible manufacturing processes using TOPCon technology is driving the global TOPCon solar cell market growth. TOPCon solar cells use N-type silicon, which offers excellent performance and balance, unlike other solar technologies, which suffer from difficulties such as excessive LID and degradation due to light and elevated temperature. In addition, several analyzes have shown that the maximum possible limit of TOPCo solar cells.

This efficiency is significantly higher than PERC cells. In addition, the efficiency increases the energy collection per unit area. TOPCon cells are bifacial in nature and can develop into an exceptionally tall bifacial. Their voltage is around 730 mV and their power can reach up to 25 degrees. The future spread of solar energy will be fueled by the growing need for distributed energy production systems in developing countries. More than 1 billion people worldwide have no or insufficient access to electricity. Photovoltaic systems along with off-grid electrification projects will increase product demand in the near future. Technological development and expansion of production capacity lead to a reduction in the total cost of the production system, which can be beneficial to the industry.

Creating high demand for renewable energy sources and growing demand for more efficient solar cells creates demand in the market

Growing demand for more efficient solar cells is driving the growth of the global TOPCon solar cell market. TOPCon solar cells using n-type silicon offer superior performance and efficiency compared to other solar technologies, making them an attractive choice for organizations seeking more efficient and sustainable energy solutions. Due to the depletion of natural resources such as oil, coal and natural gas and the negative environmental effects of fossil fuels, there has been a huge demand for renewable energy. Solar panels offer several advantages over their land-based counterparts, which is why their demand is expected to increase, especially in areas with abundant water bodies. The availability of skilled labor and government policies increased investor confidence. Countries suffering from electricity shortages are increasingly switching to renewable energy sources.

RESTRAINING FACTOR

Increased silver requirement when printing cell contacts may hinder the growth of the market 

The increased need for silver creates difficulties and factors that must be considered in terms of cost and resource use. Due to the increased use of the relatively high-priced precious metal silver in the manufacture of TOPCon solar cells, the total cost of the cells may increase. The growing demand for silver in the solar energy sector may also raise questions about sustainability and availability, as silver is a limited natural resource. Researchers and manufacturers are looking for new materials and methods to reduce the use of silver in TOPCon solar cells to solve these problems. This requires creating new contacts with better conductivity and lower material requirements, as well as improving printing processes to reduce silver waste. In addition, reducing the silver requirement of TOPCon solar cells would help reduce costs while promoting sustainability and conservation of natural resources. The goal is to find a balance between maintaining the high performance of TOPCon solar cells and optimizing the use of silver or finding substitute materials that offer comparable conductivity at lower costs and less negative environmental impact.
