Scientists demonstrated a perovskite-silicon tandem cell that reached 27% conversion efficiency. Though higher tandem cell efficiencies have been achieved, this represents a big jump in efficiency for those utilizing n-i-p architecture, which previously had not surpassed 22%.| pv magazine International
The European Solar Test Installation (ESTI) has confirmed the results of King Abdullah University of Science and Technology’s (KAUST) new perovskite/silicon tandem solar cell. The 1 cm2 device also achieved an open-circuit voltage of 1.974 V, a short-circuit current density of 20.99 mA/cm2, and a fill factor of 81.3%.| pv magazine International
