IMEC organic solar battery life extended release new method

European independent nanoelectronics research center IMEC's ​​laboratory IMOMEC recently discovered a stable form of organic solar cell nano new method, this method allows the lifetime of organic solar cells based on the original vastly improved. This breakthrough discovery on the market today organic solar battery life will reach more than 5 years, more than 10% efficiency.

   Organic photovoltaic wind turbine inverter rely mainly on the activities of its nano form the active layer can be a mixture of the organic photoelectric conversion. IMEC previously published P3HT: PCBM structure Although power generation efficiency of the solar cell close to 5%, but for the current market, its life is relatively short.

Practice has proved that, based on organic semiconductor materials for solar charge controller cell performance degradation after prolonged use, the reason is due to the organic mixture is separated into different states eventually led to the photoelectric conversion rate of decline. IMEC noted that the separation and the organic polymer in this state related activities, their activities once stable shape, the extended battery life.

   IMEC / IMOMEC experiments found that the use of new conjugated polymer type organic bulk heterojunction solar cells, after 100 hours of use, efficiency remains unchanged, which means the solar battery life greatly improved, but its power generation efficiency nearly 4%.
