perovskite solar cellssecondary aminestabilityIn article number 1903559, Edward H. Sargent, Zhijun Ning, and co﹚orkers intentionally include a secondary amine, dimethylamine, in MAPbI3 perovskite to improve the rigidity and steric hindrance for water adsorption, giving rise to reduced defect density ...
“We believe this efficiency is competitive with the highest reported for inverted perovskite solar cells composed of a mixture of 2D and 3D salts in the precursor solution, although with a less complex active layer,” the group said.Additives that can form 2D Ruddlesden–Popper (RP) per...
Doping of perovskite semiconductors1 and passivation of their grain boundaries2 remain challenging but essential for advancing high-efficiency perovskite solar cells. Particularly, it is crucial to build perovskite/indium tin oxide (ITO) Schottky co
The short‐circuit current density of inverted perovskite solar cells is unsatisfactory due to the intrinsic relatively low electron mobility and electrical conductivity of PC61BM. To solve this problem, a solution‐processed mixed‐fullerene derivative electron transporting material by mixing PC61BM ...
Considerable efforts are being made to advance inverted (p–i–n) perovskite solar cells (PSCs). Several passivation and insulation strategies have effectively been applied to reduce non-radiative recombination, a notorious issue for PSCs. Consequently, the performance of inverted PSCs has begun to...
The perovskite film fabricated from the high quality PbI2 film is highly pure, smooth and very dense even without any pinhole. The champion cell achieves a remarkable fill factor (FF) of 0.85, which is the highest value reported in perovskite solar cells. The FF value is also very ...
A novel inverted perovskite/silicon V-shaped tandem solar cell is proposed based on an elaborate design of photon matching and management, in which the underutilized above-bandgap photons and unutilized below-bandgap photons are reflected from two inverted perovskite solar cells (PSCs) to both sides...
One of the possible causes of degradation of perovskite solar cells is the instability of the electron transporting layer. In this regard, design of air stable electron transport organic semiconductors, compatible with perovskite energy levels presents challenges due to inherent vulnerability to traps, ...
