Japanese research and development of new solar cell technology conversion rate increased to 85% of expected

Nikkei News reported on the 24th, Japan's Hokkaido University Professor Shi Qiaohuang has developed a set can significantly improve the photoelectric conversion rate of solar cell technology. Reported general solar battery To conversion rate is increased to a level more than 40% is quite difficult, except Professor Shi Qiaohuang by using a variety of different types of semiconductor material, the sunlight can be half converted into electric power, on the theoretical perspective, the conversion rate of the solar cell can be increased to the 85% level. Reported that Professor Shi Qiaohuang et al principle has completed the validation phase, and plans in the early practical (production).

Reported that a new technology developed by Professor Shi Qiaohuang et al is primarily along the light advancing direction, sequentially arranged in a variety of semiconductor thin film, to thereby sequentially absorb ultraviolet, visible and infrared light. Reportedly although by sequentially stacking different size quantum dots (QuantumDot; made from a compound semiconductor, the size of several nanometer) "to improve the conversion rate of the study, provided and" quantum dot solar cells compared to The solar cell using the new technology developed by Professor Shi Qiaohuang et al easier production.

Nikkei News had reported that on April 25, 2011 solar battery leading factory in Japan Sharp has successfully resolved through the computer and the shortage of the University of Tokyo professor Chuan Tai-yin solar cell photoelectric conversion rate from about 20% of the current breath significantly increased to more than 75% of the battery construction. Sharp designed solar cell layer is covered with the quantum dots on the "face" is deposited to a grid tie inverter thickness into several μm-10μm, and electrodes on both sides thereof tops, while by the quantum dots for the most appropriate configuration, can be The existing general solar cell can not capture infrared light is converted into electric power, and thus can significantly enhance the photoelectric conversion efficiency of the solar cell.

Germany Solrico announced the world map of the solar thermal industry in 2012

The photovoltaic solar Reuters in Solarzoom headquarters in Germany, Bielefeld (Bielefeld) the City Solrico agency released the sixth edition of the world map of the solar thermal industry. Edition map than ever clearer interpretation of the global trend.
