High-efficiency solar container materials and devices

This article reviews the development status of high-efficiency c-Si heterojunction solar cells, from the materials to devices, mainly including hydrogenated amorphous silicon (a-Si:H) based silicon heterojunction technology, polycrystalline silicon (poly-Si) based. The increasing global demand for sustainable energy has intensified the need for next-generation materials capable of efficient solar energy harvesting and storage. The world PV market is currently dominated by the homo-junction crystalline silicon (c-Si) PV technology based on high temperature diffused p-n.
