Unlock the potential of low-cost and efficient solar cells!

Researchers have put forward a parallel planar heterojunction (PPHJ) strategy to enhance the efficiency of solar cells. The PPHJ device consists of two types of conventional PHJ subcells connected in parallel, using antimony trisulfide (Sb2S3) as a photovoltaic absorber. This strategy simplifies the preparation process of solar cells by allowing for the conventional sequential depositions of multiple PHJ layers without the need of an additional interfacial layer. This new approach has achieved an impressive 8.32% efficiency, the highest among all Sb2S3 devices. This study is expected to promote the development of low-cost and efficient partially or fully inorganic solar cells.
