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.

为了提高传统硅太阳能电池的能量转换效率，提出了新型硅异质结太阳能电池。以宽间隙n型微晶3C-SiC为发射层，背面非晶AlO为钝化层的p型硅太阳能电池，在国际上首次获得了16%的效率。此外，采用n型微晶硅/未掺杂SiO/p型硅片/p型微晶SiO背接触结构的新型太阳能电池效率高达18.5%。到2009财年，几乎所有的研究目标都已实现。
