Germany hybrid solar cell technology was a breakthrough
Recently, the German Institute for Microsystems Technology (Imteks) and the University of Freiburg Center for Materials Research (FMF) to date, scientists managed to develop the most efficient hybrid solar cells, the effectiveness of a maximum of 2%. g1947， rn873 ，y6142 ,Results of related research were published in the “recent” Applied Physics Letters, “on.
Organic solar cells are made from organic materials are an essential part of solar cells, belonging to the so-called third generation solar cells are still at the research stage. Compared to silicon solar cells usually organic solar cells, thin and flexible, low cost and fast production. Despite its light conversion efficiency is not high, the partial life is short, but its role in the integration of applications and for a limited system allows self-sufficiency in energy, have prospects of wide application.
Pure organic solar cells, optical active layer of the two components of the composition of organic matter by. The hybrid solar cells, photoactive layer consists of nano particles and inorganic (organic) polymer blend. Through the use of so-called quantum points cadmium selenide, Germany, sony vgp-bps11 , sony vgp-bpl11 ,Micro Systems Technology Institute and the University of Freiburg Materials Research Center researchers have successfully developed a method of surface treatment of nanoparticles may significantly improve the efficiency organic solar cells, up to 2% return rate. The outcome measure was the Fraunhofer Institute for Solar Energy Systems (ISE) “Dyes and organic solar cells, the Working Group confirmed. Prior to the effective value of only 1% to 1.8%. The Current research and development of this approach in principle applicable to a variety of nano-particles, to further improve the efficiency of such solar cells has opened up broad prospects.
