HIGHLY EFFICIENT PEROVSKITE/Cu(In, Ga)Se2 TANDEM SOLAR CELL

摘要

A monolithic tandem photovoltaic cell includes a first electrode; a CIGS light absorption section on the first electrode; an interconnecting layer on the CIGS light absorption section; and a perovskite light absorption section on the inter-connecting layer. The interconnecting layer has a polished surface on which the perovskite light absorption section is formed. The interconnecting layer provides an electrically conducting and optically transparent connection between the CIGS light absorption section and the perovskite light absorption section.
