Solar cell, also known as "solar chip" or "photocell", is a photoelectric semiconductor wafer directly generated by sunlight. Single cell solar cells can not be used directly for power supply. As a power source, several single solar cells must be connected in series and connected in parallel and tightly packaged into components.
Solar panels (also called solar cell components) are assembled. It is the core part of the solar power generation system and the most important part of the solar power generation system.
