Organometal halide perovskite-based solar cells have recently realized large conversion efficiency over 15% showing great promise for a new scale cost-competitive photovoltaic technology. Using impedance spectroscopy measurements we are able to separate the physical parameters of carrier transport and recombination in working devices two principal morphologies compositions perovskite cells, viz. compact thin films CH3NH3PbI(3-x)Clx CH3NH3PbI3 infiltrated on nanostructured TiO2.

Strategies of how to mitigate photodegradation and thermal degradation processes are proposed in this work order further improve operational stability hybrid perovskite solar cells.
Organic-inorganic halide perovskite materials (e.g., MAPbI3, FAPbI3, etc.; where MA = CH3NH3+, FA CH(NH2)2+) have been studied intensively for photovoltaic applications. Major concerns the commercialization of technology to take off include lead toxicity, long-term stability, hysteresis, and optimal bandgap. Therefore, there is still need further exploration alternative candidates. Elemental composition engineering MAPbI3 FAPbI3 has proposed address above concerns. Among best six certified...
The thermal stability and decomposition products of formamidinium, a widely used organic cation in perovskite solar cell formulation, were investigated.
The use of a solid hole transport layer (HTL) was transformational for the recent perovskite solar cell (PSC) revolution in energy technology. Often high efficiency PSC devices employ heavily doped materials such as spiro-MeOTAD. Independent HTL chemistry, lithium-bis-trifluoromethanesulfonyl-imide (LiTFSI) and tert-butylpyridine (TBP) are commonly used additives formulations PSCs. LiTFSI TBP were originally optimized dye-sensitized cells, where their roles have been extensively studied....
Abstract Large datasets are now ubiquitous as technology enables higher-throughput experiments, but rarely can a research field truly benefit from the data generated due to inconsistent formatting, undocumented storage or improper dissemination.

We collect over 42,400 photovoltaic devices with up 100 parameters per device. then develop...
Abstract Mixed cation hybrid perovskites such as Cs x FA 1− PbI 3 are promising materials for solar cell applications, due to their excellent photoelectronic properties and improved stability.
