During the working process of the thin film solar cell, light is projected onto the glass substrate 10 and passes through the transparent electrode 11 to reach the amorphous silicon photovoltaic unit. The amorphous silicon photovoltaic unit converts light signals into electrical signals, and the electrical signals are output through the transparent electrode 11 and the bottom electrode 15 .
