Indian scientists build 4T perovskite-silicon tandem cell based on hybrid heterojunction PV device

A research group in India has embedded a hybrid heterojunction solar cell as a bottom device in a four-terminal perovskite-silicon solar cell using a solution processing technique. The novel cell architecture, according to its creators, could be produced at significantly lower costs compared to conventional perovskite-silicon tandem designs. A group of researchers led by the Indian Institute of Technology Roorkee has proposed to use hybrid heterojunction solar cells (HHSCs) as bottom devices in four-terminal (4T) perovskite-silicon tandem PV cells. The scientists explained that HHSCs have a simple ...
