Application of Au@SiO2 Plasmonic Nanoparticles at Interface of TiO2 Mesoporous Layers in Perovskite Solar Cells
To investigate the plasmonic effect in perovskite solar cells, the effect of depositing Au@SiO2 nanoparticles on the top and the bottom of mesoporous TiO2 layers was studied. First, Au@SiO2 nanoparticles were synthesized. The particles were then deposited at the different interfaces of mesoporous TiO2 layers. Although the two structures show approximately similar optical absorption, only cells ...
متن کاملOne-Year stable perovskite solar cells by 2D/3D interface engineering
Despite the impressive photovoltaic performances with power conversion efficiency beyond 22%, perovskite solar cells are poorly stable under operation, failing by far the market requirements. Various technological approaches have been proposed to overcome the instability problem, which, while delivering appreciable incremental improvements, are still far from a market-proof solution. Here we sh...
متن کاملStable and durable CH3NH3PbI3 perovskite solar cells at ambient conditions.
Degradation of metal-organic halide perovskites when exposed to ambient conditions is a crucial issue that needs to be addressed for commercial viability of perovskite solar cells (PSCs). Here, a concept of encapsulating CH3NH3PbI3 perovskite crystals with a multi-functional graphene-polyaniline (PANI) composite coating to protect the perovskite against degradation from moisture, oxygen and UV ...
متن کاملPerovskite Solar Cells
Two-dimensional hybrid perovskites are used as absorbers in solar cells. Our first-generation devices containing (PEA)2(MA)2[Pb3I10] (1; PEA=C6H5(CH2)2NH3 , MA= CH3NH3 ) show an open-circuit voltage of 1.18 V and a power conversion efficiency of 4.73%. The layered structure allows for high-quality films to be deposited through spin coating and high-temperature annealing is not required for devi...
متن کاملStable and efficient hole transporting materials with a dimethylfluorenylamino moiety for perovskite solar cells.
Novel star-shaped hole transporting materials (HTMs) with a bis-dimethylfluorenylamino moiety have been synthesized and evaluated for high performance perovskite solar cell applications. Maximum power conversion efficiency of 14.21% has been achieved by using the HTM with a fused TPA core and the long-term stability was also shown to be comparable with that of .
