Solar panels are devices that can convert solar energy into electricity, also known as "solar panels" or "photovoltaic panels". It consists of many solar cells made of semiconductor materials such as silicon, selenium, and copper indium gallium sulfur. When sunlight shines on a solar cell, its energy is absorbed and electron hole pairs are generated. These electrons and holes will move and form an electric current in the circuit, generating energy. Solar panels have become a renewable, clean, and economical energy choice, and are being applied in more and more fields. In the future, with the continuous improvement and popularization of technology, it is expected to become a more mainstream energy source.
