Question

How do photovoltaic cells convert solar energy into electricity?

Answer 1

Abstract The dye-sensitized solar cell (DSC) provides a technically and economically credible alternative concept to present day p–n junction photovoltaic devices. In contrast to the conventional silicon systems, where the semiconductor assumes both the task of light absorption and charge carrier transport the two functions are separated here. Light is absorbed by a sensitizer, which is anchored to the surface of a wide band gap oxide semiconductor. Charge separation takes place at the interface via photo-induced electron …

• Photovoltaic cells generate electricity by absorbing sunlight and using that light energy to create an electrical current.
• When light shines on the cell it creates an electric field across the layers causing electricity to flow.
• Photovoltaic Cell are used to produce electricity which powers a water pump, well etc.
