The technology of solar cells has been developed as a result of the need for long-lasting power supplies for satellites and space vehicles. The device is based on the photovoltaic effect in the photodiode. With no external bias a photodiode will deliver power to a load resistance if irradiated by light with photons of sufficient energy. By making the collection area as large as possible, the solar cell will deliver a large photocurrent from direct illumination by sunlight. A solar cell with a collection area of 30 cm2 and a power conversion efficiency of 10 per cent will deliver 300 mW to a load if illuminated by bright sunlight.
