RESEARCH OF COMMERCIAL BIFACIAL SILICON SOLAR CELLS
Because of the special finger shape and junction structure, bifacial silicon solar cells could receive sunlight from both sides. So the cells can absorb much sunlight, have less strict require for installation, and have higher conversion efficiency. We have done research in commercial bifacial silicon solar cells. We designed the bifacial silicon solar cells with realizable structure and high conversion efficiency. We designed and realized proper technics path, which are used to fabricate these bifacial solar cells. The boron backfield is used. The anti-reflection coating and finger contact are fabricated on both surfaces of the solar cells, so the cells have different contact structure. Meanwhile, we realized ohmic contact between finger contacts and surface of solar cells on both sides. We successfully produced the bifacial silicon solar cells with the front and rear efficiencies exceed 15％ and 9％(AM1.5, 25℃), respectively, and which can be produced in large-scale.
