Research of Blue/Red Reflecting for Space Silicon Solar Cell

The non-reflective silicon cells could increase cell efficiency in comparison to cells with smooth surface,while they would also increase the operational temperature as IR and UV energy is efficiently absorbed.This temperature increase completely offsets the initial efficiency gain when the non-reflective silicon cells were used in space.A Blue/Red Reflecting(BRR) for space silicon solar cell has been developed to improve the performance of silicon solar cell.The BRR consists of UVR on the front surface of the coverglass and the IRR on the rear surface produced in method of electron-beam gun evaporation with ion-assisted deposition.The operating temperature reduction between 6℃and 12℃and the in-orbit efficiency gains between 1.8%and 4.1%for silicon solar cell with BRR have been predicted.The potential benefits of the BRR are greatest for the non-reflective silicon cells.
