Abstract
Tandem cells with perovskite absorbers are an active area of research. Here we consider various architectures for perovskite/CdSeTe tandems. One near term option is to form a wide bandgap perovskite top pin cell on the glass side of a CdSeTe bottom cell in a four terminal (4T) configuration. The tandem can be operated in 2T mode by internally connecting the electrodes. A technoeconomic analysis of the 4T configuration shows lower cost than crystalline Si and CdSeTe single junction and perovskite/Si tandem modules when all fabrication is done in the U.S. Device were fabricated with preliminary efficiencies of 16.7% and 13.5% for the 4T and 2T configurations, respectively. Quantum efficiency measurements suggest pathways to improve device performance.
