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 کاملThe electronic structure of metal oxide/organo metal halide perovskite junctions in perovskite based solar cells
Cross-sections of a hole-conductor-free CH3NH3PbI3 perovskite solar cell were characterized with Kelvin probe force microscopy. A depletion region width of about 45 nm was determined from the measured potential profiles at the interface between CH3NH3PbI3 and nanocrystalline TiO2, whereas a negligible depletion was measured at the CH3NH3PbI3/Al2O3 interface. A complete solar cell can be realize...
متن کاملEnhancement of Perovskite Solar Cells by Plasmonic Nanoparticles
Synthetic perovskites with photovoltaic properties open a new era in solar photovoltaics. Due to high optical absorption perovskite-based thin-film solar cells are usually considered as fully absorbing solar radiation on condition of ideal blooming. However, it is not really so. The analysis of the literature data has shown that the absorbance of all photovoltaic pervoskites has the spectral ho...
متن کاملInterfacial Kinetics of Efficient Perovskite Solar Cells
Perovskite solar cells (PSCs) have immense potential for high power conversion efficiency with an ease of fabrication procedure. The fundamental understanding of interfacial kinetics in PSCs is crucial for further improving of their photovoltaic performance. Herein we use the current-voltage (J-V) characteristics and impedance spectroscopy (IS) measurements to probe the interfacial kinetics on ...
