2015 times the power of solar cells up to 50%

London First Conferences Company "concentrator photovoltaic today," Division 30 March, 2009 issued a condenser about the commercialization of photovoltaic technology bottlenecks faced by the report. The report concluded that, to 2015 by the III-V semiconductor materials (GaInP / GaInAs / Ge) solar cells composed of many times the power will be increased to 50%. Germany's Fraunhofer Institute Solar Energy Systems in sunlight into electricity the first time to create up to 454 times the power of concentrating the world record of 41.1 percent. This highly efficient solar cells which power the photovoltaic technology in the current top.

"Today, photovoltaic concentrator" that carry out highly efficient conversion of solar energy to electrical energy has become increasingly important, because stratified solar cells solar power together with the degree of improvement and growth, and the high temperature battery in particular. At present, the photovoltaic system condenser 2-1000 at times under the conditions of the condenser is running. Solar cells because of the cool way to more sophisticated, and constantly has been the use of new materials, solar cells condenser times have increased the space index.

The survey also describes the factors which affect the solar cells power many times, and a detailed study of materials used in batteries. At present, photovoltaic equipment, both the condenser silicon high-power batteries, solar cells have many times, but compared with the silicon cells from III-V semiconductor materials composed of the same cell has not yet reached market maturity, as well as industrial production standards . The study of the times of commercial solar cells made the following goal: "to reach 45% of battery power, solar power reaches 35% of the template, complete photovoltaic system condenser up to 30%, this can significantly reduce production costs.
