Solar cell: Utilizing solar energy for electrical energy conversion, also known as solar photocell or photodiode, is a device that can convert sunlight into electrical energy. It uses the principle of Photoelectric effect to convert light energy into electric energy. The main component of solar cells is semiconductor materials, with silicon solar cells being the most common type.

Working principle: The interaction between photogenerated voltage and photogenerated current The working principle of silicon solar cells is to generate photogenerated current based on the photogenerated potential difference, thereby achieving energy conversion. When the sunlight shines on the silicon solar cell, the photons interact with the atoms in the silicon material to convert the photon energy into electronic energy. Under the action of photogenerated potential difference, electrons are pushed forward to form photogenerated current. Due to the fact that silicon solar cells are usually composed of multiple units, which are connected by metal wires to achieve external output of current.
