Topcon Solar Cell

Solar cells are the core components in solar photovoltaic power generation systems, used to convert solar energy directly into electrical energy. They are mainly composed of two types: crystalline silicon (including monocrystalline silicon and polycrystalline silicon) and amorphous silicon (also known as thin-film cells). Crystalline silicon cells are made by growing high-purity silicon materials into a whole crystal or using broken high-purity silicon blocks. They have high conversion efficiency and long service life. Amorphous silicon cells use thin-film technology, and the manufacturing process is relatively simple, suitable for large-scale production, but the conversion efficiency is relatively low.
