On the methods of calculation of the charge collection efficiency of dye sensitized solar cells
Royal Society of Chemistry (2013)The charge collection efficiency is one of the most critical parameters of photovoltaic devices. In this paper we provide the analysis and comparison between several approaches for the calculation of the collection efficiency ... -
Organo-metal halide perovskite-based solar cells with CuSCN as the inorganic hole selective contact
Royal Society of Chemistry (2014-06)CuSCN is proposed as a cost-competitive hole selective contact for the emerging organo-metal halide perovskite-based solar cells. The CuSCN films have been deposited by a solution casting technique, which has proven to be ... -
Photoinduced Giant Dielectric Constant in Lead Halide Perovskite Solar Cells
American Chemical Society (2014-06)Organic-inorganic lead trihalide perovskites have emerged as an outstanding photovoltaic material that demonstrated a high 17.9% conversion efficiency of sunlight to electricity in a short time. We have found a giant ... -
Plasmon-enhanced photocurrent in quasi-solid-state dye-sensitized solar cells by the inclusion of gold/silica core–shell nanoparticles in a TiO2 photoanode
Royal Society of Chemistry (2013-09)Direct evidence of the effects of the localized surface plasmon resonance (LSPR) of gold nanoparticles (Au NPs) in TiO2 photoanodes on the performance enhancement in quasi-solid-state dye-sensitized solar cells (DSCs) is ... -
Recombination in Quantum Dot Sensitized Solar Cells
American Chemical Society (2009-11)Quantum dot sensitized solar cells (QDSCs) have attracted significant attention as promising third-generation photovoltaic devices. In the form of quantum dots (QDs), the semiconductor sensitizers have very useful and often ... -
Relaxation of Photogenerated Carriers in P3HT:PCBM Organic Blends
Wiley (2009)Relaxing in the sunlight. Long time-transient decays of photogenerated carriers in P3HT:PCBM blends for organic solar cells are interpreted in terms of the relaxation of hole carriers in a broad density of states. The ... -
Removing Instability-Caused Low-Frequency Features in Small Perturbation Spectra of Perovskite Solar Cells
American Chemical Society (2020-06-29)Small-perturbation frequency-domain techniques such as impedance spectroscopy and intensity-modulated photocurrent spectroscopy (IMPS) have become important methods for the investigation of the physical working mechanisms ... -
Solution-processed small molecule:fullerene bulk-heterojunction solar cells: impedance spectroscopy deduced bulk and interfacial limits to fill-factors
Royal Society of Chemistry (2013)Using impedance spectroscopy, we demonstrate that the low fill factor (FF) typically observed in small molecule solar cells is due to hindered carrier transport through the active layer and hindered charge transfer through ... -
Surface Recombination and Collection Efficiency in Perovskite Solar Cells from Impedance Analysis
American Chemical Society (2016-11)The large diffusion lengths recurrently measured in perovskite single crystals and films signal small bulk nonradiative recombination flux and locate the dominant carrier recombination processes at the outer interfaces. ... -
Synthesis of a Fully Conjugated Phthalocyanine-Diketopyrrolopyrrole-Phthalocyanine Triad ow Band Gap Donor in Small Molecule Bulk Heterojunction Solar Cells
Wiley-VCH (2014)We describe the synthesis and photovoltaic properties of a fully conjugated phthalocyanine-diketopyrrolopyrrole-phthalocyanine triad (ZnPc-DPP-ZnPc) that presents strong visible absorption from 400 to 900 nm. The synthesis ... -
Temperature effects in dye-sensitized solar cells
Royal Society of Chemistry (2013)In the standard solar cell technologies such as crystalline silicon and cadmium telluride, increments of temperature in the cell produce large variations in the energy conversion efficiency, which decreases at a constant ... -
