Well, technically, no. Solar panels and photovoltaic cells are two distinct parts of your solar photovoltaic system. A photovoltaic cell is a single electronic component containing layers of silicon semiconductors that convert solar energy into electrical energy. A solar panel, on the other hand, is an assembly of multiple photovoltaic cells.
Photovoltaic cells absorb solar radiation of wavelength between 700 nm and 1100 nm while shorter and longer wavelengths increase the temperature of the panel [254–256]. As the cell temperature increases, reduction in band gap of photovoltaic semiconductor occurs which reduces the voltage generated by each photovoltaic cell. This reduces
