The concept behind the tunnel oxide passivated contact (TOPCon) technique is that the metallic component does not come into proximity with the wafer. The N-type silicon substrate of TOPCon is covered with an extremely thin film of tunneling oxide, which is subsequently followed by an additional layer of highly doped polysilicon that connects the metal at the edges. TOPCon solar cells have exceptional efficiency, minimal investment requirements, and the flexibility to readily fit into existing module design specifications. Furthermore, when compared to other solar cell technologies, TOPCon solar cells have demonstrated lower deterioration rates. This implies that they can continue to work at a high level for a longer time, leading to more steady electricity production and a longer lifespan. Numerous industries, including residential, commercial, and utility-scale solar installations, use TOPCon solar cells. They are appropriate for various solar project categories owing to their strong performance and efficiency levels.
The global TOPCon solar cells market was valued at $7.54 billion in 2022 and is anticipated to reach $40.69 billion by 2032, witnessing a CAGR of 19.8% during the forecast period 2023-2032.
Additionally, the TOPCon solar cells market has seen an increase in demand due to the increased upper level of efficiency. The open-circuit voltage of TOPCon solar cells has the potential to increase, which is crucial for overall cell efficiency. Higher voltage output is made possible by the passivated contact structure's reduction of losses at the contact surfaces. In comparison to conventional solar cells, TOPCon solar cells often have a lower temperature coefficient. This indicates that temperature changes have less of an impact on their performance, enabling them to continue operating at higher efficiency even in hot weather. The higher upper level of efficiency that TOPCon solar cells provide makes them appealing for a variety of applications, including utility-scale solar power plants, commercial installations, and residential rooftop systems.
Based on end user, the residential segment led the TOPCon solar cells market in 2022 and was the largest segment due to the rising consumer demand for solar cells. A number of countries, including the U.S., U.K., Germany, and India, have adopted high goals to boost the proportion of renewable energy in their power mix.
The implementation of residence solar PV systems is a measure that the governing bodies of these countries have also intended to accomplish in the upcoming years (2023-2032) to boost the percentage of renewable energy. The producers and suppliers of solar cells for the residential sector are anticipated to benefit from this during the projected period.

Furthermore, China’s fast-developing economy and the presence of leading industry players across the TOPCon solar cells component’s supply chain are having a prominent effect on the growth of the TOPCon solar cells market.
Scope of the Study
BIS Research has considered the definition as per “Industry players, Oxford PV,” TOPCon solar cells is a technology that combines passivated contacts with a tunnel oxide layer to create a low-resistance contact structure, enabling higher conversion efficiencies and enhanced power output. The TOPCon technology is associated with N-type cells. A silicon wafer is used in the production of P-type and N-type solar cells. The distinction between N-type and P-type originates from the substance utilized to dope the silicon wafer, which is done to enhance power output. Boron is added to P-type cells, while phosphorus is added to N-type cells. When compared to boron, phosphorus has the benefit that phosphorus cannot be degraded by oxygen, but boron can. Additionally, phosphorus doping boosts effectiveness by introducing electrons that are liberated to the wafer. The efficiency of the cell and module is higher with TOPCon cells than with P-type cells, as they assimilate a greater amount of sunlight.
