Scientists Come Up With New Process For Hydrogen Water Splitting

Inverted perovskite solar cell with 24 1% efficiency

An international research group has developed an inverted perovskite solar cell with an active area of 9.6 mm2 by using polymer dipoles for interfacial engineering. It retained 96% of its initial power conversion efficiency after continuous maximum power point (MPP) tracking for 1,000 hours.

New cushion solution to take stress off perovskite solar cells – pv magazine International

Scientists in Germany have discovered a polymer compound that, when added to perovskite thin-film precursor materials, wraps itself around the perovskite crystals, acting as a cushion to protect the perovskite structure from thermomechanical stress. They used the additive to fabricate cells with up to 24.6% efficiency, retaining 96% of their initial performance after accelerated testing equivalent to one year in the field.
