The solution for a cheaper energy
New discoveries within the silicon solar cell design allowed the three companies break the record for energy efficiency, established 20 years ago. During the Conference, IEEE Photovoltaic Specialists in Denver, Panasonic, Sharp and SunPower presented new photovoltaic cells that exceeded the old barriers to efficiency. It is expected that this increase will enable the solar energy efficiency compete commercially with fossil fuels.Traditional silicon solar cells have the positive poles in contact with the surface of the Panel, which actually creates shadows on the surface, reducing the efficiency of the unit as a whole. When transferring the poles for the reverse side of the Panel, where are the negative poles, the efficiency is increased. The discovery was fair by SunPower.Another improvement was introduced by Panasonic. Most of the Silicon cells, the electrons become trapped by the superficial imperfections of joints of crystalline silicon cells. To avoid this the Panasonic added thin film of silicon to the verses of the cells. This new improvement allows to achieve an efficiency rate of 25.6%, as the new design of SunPower untrapassou the barrier of 25%, referred to Inhabitat. Despite the theoretical level advances don't look sizable, at a practical level the amount of energy produced is much better.New advances are not yet ready to be produced commercially, but open doors for new advances in this field, horizon reduce the ultimate cost to the consumer.
