Enhancement of the Photovoltaic Cell Performance

Hadi Ali Madkhali*

The world is looking for new sources of electrical energy instead of traditional sources because two main reasons: to create a clean environment and to have lower energy costs. Solar energy is coming to be at the forefront of renewable and sustainable energy; it assists to treat global pollution and considers an effective and reliable source of electrical energy. Solar Photovoltaic technology is one of the most important resources    of clean energy. It uses cells to convert sunlight energy into electrical energy. This source of electrical energy has wider use than other sources of renewable energy due to the amount of power that can be produced. However, photovoltaic cells utilize only a small portion of the radiation emitted by the sun which is the visible light while the entire spectrum of solar radiation can potentially be converted into heat. The temperature plays an important role in the performance of the solar cell system. As the cell temperature increases, the performance of the system goes down. In this paper, thermal and visible radiations have been combined as a hybrid system for treating the temperature effects and achieving the high efficiency of the new solar module.
