Cooling techniques for enhancing of photovoltaic cell efficiency: Review

The current energy requirements are mostly met by fossil fuels and non-renewable sources which depleting at rapid rate besides being emitters of greenhouse gases, so the solutions depend on renewable energy. Solar is one these clean energies, that inexhaustible has no emissions. solar radiation falling photovoltaic cells, part it converted into electrical other this heat, causes decrease in efficiency cell. In general, performance cells decreases 0.5% for each degree temperature rise, depends type material used. Therefore, was necessary to solve problem controlling operating various cooling techniques, especially areas with high temperatures, order increase cells. This work, been reviewed studies research conducted recent years techniques analyzed results. These methods include natural air cooling, forced passive water active pcm cooling. results showed (forced or air) more efficient than methods, as expected. However, require costs construction maintenance, addition consume energy, possible replace instead because may lead gain some cases if consumed pumping taken consideration reduce costs. using hybrid / thermal system (pv \ t), better heat rejected can be As have very hot climate, preferable use front water, considered economical. Cooling phase change materials increases production also gives an opportunity But method less cost installing high.
