| چکیده [English] | ||
| Semiconductors are used in photovoltaic energy converters to produce electric energy. Solar cell is not a heat engine ,however, it is rather a quantum mechanical device. A single crystal of semiconductor material is doped in such a manner that the bottom portion of the crystal is n-type and the top is p-type. if we illuminate this thin wafer with light of a given frequency a hole-electron is produced which diffuses towards the p-n junction, i.e. the transition region. if a resistor (i.e. electrical load) is placed in the circuit to connect this (p-n) junction an electric current will pass from that. In this device solar energy is converted directly to electric power. | ||
