Another device that harnesses solar energy is the solar cell. Solar cells are expensive and are used only when supplying electricity becomes difficult. Solar cells are the devices where solar energy is directly convert..

Junction diodes are of many types and solar cells are one such. Its working is based on production of potential difference by sunlight. In other words, it is a junction diode that can convert light energy into electrical energy. In such a junction one of them either P or N is ma..

Sun is the biggest source of non-conventional energy. Energy is in the form of photons. India receives abundant sunlight for about 250-300 days in a year. Conversion of solar energy to electric energy and thermal energy takes place mainly by photovoltaic cells and through ..

Solar cell is a very thin sandwich of n-type and p-type wafer thin semiconductors of silicon. A U-shaped metal grid is embedded into the thin semiconductor chip as shown in the fig. The lower end of the sandwich is fixed to a metal base which has a metal lead. The grid has a l..

It is present in abundance They have no moving parts and hence require little maintenance and work quite satisfactorily without any focusing device It does not cause any environmental pollution like the fossil fuels and nuclear power Solar cells last a longer time and have ..

Semiconductors whose conductivity is more than insulators and less than metals are used in electronic devices. The conductivity of the semiconductors increase when light falls on it. Wafers of doped semiconductors are so arranged that when sunlight falls on the arrangement, potential differences ar..

Photocells are used in television camera to reproduce sound recorded on films, in counting devices, in burglar and fire alarms, to measure the temperature of stars, to study the spectrum of heavy bodies, to operate street light, to compare the illuminating powers of two sources, in photometers, for..
