Modern image sensors necessitate three color‐selective photodetectors: red, green, and blue (RGB) sensing units. Among those, blue light‐specific photodetectors are comparably much less reported. Here, a fully thermal‐evaporated organic photodetector (OPD) with narrowband blue detection based on exploring the dual role of the hole‐transporting layer is elegantly demonstrated. By incorporating a MoO...
Perovskite photovoltaic (PV) cells have demonstrated power conversion efficiencies (PCE) that are close to those of monocrystalline silicon cells; however, in contrast to silicon PV, perovskites are not limited by Auger recombination under 1‐sun illumination. Nevertheless, compared to GaAs and monocrystalline silicon PV, perovskite cells have significantly lower fill factors due to a combination of...
