The operation of a photovoltaic (PV) cell requires 3 basic attributes:
The operation of a photovoltaic (PV) cell requires 3 basic attributes:
#The absorption of light, generating either electron-hole pairs.
#The separation of charge carriers of opposite types.
A '''solar thermal collector''' collects heat by absorbing sunlight. A collector is a device for capturing solar radiation. Solar radiation is energy in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The quantity of solar energy striking the Earth's surface averages about 1,000 watts per square meter under clear skies, depending upon weather conditions, location and orientation.
