In order to achieve national carbon neutrality by 2050, the Tokyo Metropolitan Government has passed an ordinance requiring housing manufacturers to install photovoltaic power generation systems in newly constructed detached houses starting in April 2025. Other prefectures have also established subsidies for photovoltaic power generation systems to promote their installation in homes. Meanwhile, electricity prices are rising year by year, making it increasingly important to curb electricity costs through on-site consumption of electricity by solar power generation systems and income from the sale of electricity.

The roofs of Japanese homes are small in area, and improving the output of solar cell modules is essential for obtaining the electricity needed for daily life within a limited footprint. We have been increasing output by shifting from polycrystalline to monocrystalline and from full-size to half-cut cells, with a focus on P-type cells. We now offer high-power solar cell modules that employ N-type cells, which contribute to higher output, and TOPCon 4.0, a manufacturing process that maximizes the performance of N-type cells. N-type solar cell modules have higher output per unit area than P-type solar cell modules, less degradation over time, and higher power generation in low-light conditions, resulting in higher lifetime power generation(*1).

(*1) With this N-type solar cell module, we will continue to promote the spread of photovoltaic power generation systems in homes.

Features of the N-type solar cell module

(1)Installation of N-type TOPCon cell

The latest process technology TOPCon4.0 is used for N-type cells. It features higher conversion efficiency than conventional P-type cells and lower LID (Light Induced Degradation) and annual aging degradation rates, resulting in improved lifetime power generation of the solar cell module(*1).

(2) Excellent temperature and low-light characteristics and high reliability

Compared to P-type cells, the new module has a lower temperature coefficient and superior low-illumination characteristics, resulting in higher power generation in summer and on cloudy days. In addition, the number of bus bars has been increased from 11 to 16, and the bus bar spacing has been narrowed to reduce electrical resistance and improve power generation efficiency. In addition, resistance to cell cracks and uniform stress distribution in the cells have been achieved, resulting in improved reliability.
