Were Obtained Advanced Solar Cells by Using Nanocrystals

In recent years solar cells have had a constant capacity to hold solar energy.Recent apeared the problem of increasing capacity of solar cells.The principle of solar cells working is quite simple.When 1 photon of light is received it is transformed into 1 electron.Usually sun energy is captured in its entirely but there are also cases when the energy is lost due the low reception capacity.With an solar energy multiplier solar energy is not lost, it can be recovered in full.Also disclosed and certain materials such as nanocrystals from semiconductor materials can receive the same amount of light and can generate more (receive a photon and emit more electrons). The maximum level reached by researchers is almost 10 electrons by capturing 1 foton.Researchers concluded that the same amount of energy captured from the sun may make different electricity depending on how it is retained.Statistics results show that solar energy is lost through the most methods of retaining.So, in conclusion, to receive as much solar energy possible,you need a good material that retains solar power and a good method applied for capture the light fully.
