摘要（英）：

The utility model discloses a silica -based solar cell of graphite alkene with annular insulation layer structure, including the back electrode, set up monocrystalline silicon piece on the back electrode, the last silicon dioxide layer that sets up of monocrystalline silicon piece, silicon dioxide layer is the annular structure that has the through -hole, and thickness that silicon dioxide layer was absorbed in monocrystalline silicon piece is 0.2~2 mu m, silicon dioxide layer's surface and the monocrystalline silicon piece surface who is exposed by the silicon dioxide layer through -hole set up graphene films, the graphene films surface sets up preceding electrode. Apparent improvement has been compared to silica -based solar cell of graphite alkene with annular insulation layer structure's efficiency with traditional structure.
