Solar cells (photo voltaic cells) - are they useful ?Solar cells are devices which convert energy of sunlight directly into electrical energy by photo electric effect. Assemblies of cells are used to make solar panels. Solar cells contain sandwiched combination of n-type and p-type semiconductors. Solar cells usually have a sheet of glass in the front allowing the sunlight to pass through while protecting the semiconductoring material from the impact of rain, wind, abrassion etc.
Uses1) For power production in artificial satellites and space vehicles.
2) Used in watches, calculators, solar water heater, solar cookers, etc.
3) For street lighting.
4) For power production in light house and offshore rigs and refineries.
Is production of electricity more useful and economical by solar cells than other methods. Why the use of devices and other electronic equipments not that much used in Kerala. Will it be practically useful if every house implements solar panels for their daily power requirements ? Do respond.
