Mitsubishi motors display of polycrystalline silicon solar energy cell efficiency 19.1% respectively
Mitsubishi motors in October 2009 28-30 at the yokohama exhibition center held the Pacific “GreenDevice2009″ displayed on the high efficiency solar battery polysilicon 19.1% respectively. In the square 15cm in polysilicon solar cells, realized the highest efficiency. The research achievements in 2009 September 2009 and the application of physics to the international society in October EUPVSEC “, “said in a statement.

Promote efficiency of conversion factors include reducing unit of normal cellular structure “reflection”, increase HoneycombTexture (unit) the amount of reflected light BSR bucksurfacereflector) “, “(with speed, lower back on the back of the Passivation (Passivation) structure, and further improve the state of the environment of hydrogen heat, etc.
Therefore, the battery voltage (Voc) for open 0.65 V, short-circuit current (Isc) for A, fill factor (8.45 F.F.) for 75.7% respectively, unit conversion efficiency reached 19.1% respectively. These values by Japanese industrial technology integrated research institute.
The company of “in” GreenDevice2009 WorldPVShowcase “exhibition display the conversion efficiency reached 19.1% respectively. In addition, in WorldPVShowcase galleries display and sharp the conversion efficiency reached more than three compounds and 35.8 percent of solar cells.
