Solar Panel Efficiency of Photovoltaic Cells

Photovoltaic cells have been a major breakthrough invention in the field of energy science. Since the working principles to convert solar energy into electricity discovered, we gradually able to develop solar panel and thus use it as an alternative energy source, from the scale of the solar field to the ones that are used in residential buildings. Another problem that challenged engineers & scientists as the development of solar panel technology arose is efficiency: How can we extract as much solar energy as possible even from the low intensity of the sunlight exposure or other technical problems.
