In conventional photovoltaic systems, the cell responds to only a portion of the energy in the full solar spectrum, and the rest of the solar radiation is converted to heat, which increases the temperature of the cell and thus reduces the photovoltaic conversion efficiency [[8], [9], [10]].Silicon-based solar cells are the most productive and widely traded cells available [11, 12].
Although crystalline PV cells dominate the market, cells can also be made from thin films—making them much more flexible and durable. One type of thin film PV cell is amorphous silicon (a-Si) which is produced by depositing thin layers of silicon on to a glass substrate.
