Reducing sputter induced stress and damage for efficient perovskite/silicon tandem solar cells

Reducing damages caused by sputtering of transparent conductive oxide (TCO) electrodes is critical in achieving highly efficient and stable perovskite/silicon tandem solar cells. Here we study the sputter caused damage...

Robust Molecular Dipole Induced Surface Functionalization of Inorganic Perovskites for Efficient Solar Cells

CsPbI3 inorganic perovskite shows high potential for single-junction or tandem solar cells due to its suitable bandgap energy (Eg=~1.7 eV), but defect-assisted nonradiative recombination and unmatched interfacial band alignment within...

Understanding and suppressing non-radiative losses in methylammonium-free wide-bandgap perovskite solar cells

With power conversion efficiencies of perovskite-on-silicon and all-perovskite tandem solar cells increasing at rapid pace, wide bandgap (> 1.7 eV) metal-halide perovskites (MHPs) are becoming a major focus of academic...
