Novel Si heterojunction solar cells were proposed to improve the energy conversion efficiency of conventional Si solar cells. For p-type Si solar cells with a widegap n-type micorcystalline 3C-SiC as an emitter layer and with an amorphous AlO as a backside passivation layer, an efficiency of 16% was demonstrated for the first time in the world. Furthermore, very high efficiency of 18.5% has been achieved for a novel solar cell with a configuration of n-type microcrystalline Si/undoped-SiO/p-type Si wafer/p-type microcrystalline SiO back contact. Almost all research targets were met by FY2009.
