Cooperative kinetics of depolarization in CH3NH3PbI3 perovskite solar cells
Royal Society of Chemistry (2015)Despite the large photovoltaic performance recently achieved, many aspects of the working principles of hybrid organic–inorganic perovskite solar cells remain to be unveiled. We analyze the experimental features observed ... -
Effect of different lead precursors on perovskite solar cell performance and stability
Royal Society of Chemistry (2014-12)We present the use of halide (PbCl2) and non-halide lead precursors (Pb(OAc)2 (OAc = CH3CH2COO−), Pb(NO3)2, Pb(acac)2 (acac = (CH3COCHCOCH3)−) and PbCO3) for the preparation of perovskite solar cells. We have confirmed by ... -
Fast and low temperature growth of electron transport layers for efficient perovskite solar cells
Royal Society of Chemistry (2015-01)We describe a fast, simple and low temperature electrochemical technique for the preparation of zinc oxide layers on rigid and flexible substrates. The layers, prepared from a zinc nitrate precursor, are of high structural ... -
Inorganic Surface Engineering to Enhance Perovskite Solar Cell Efficiency
American Chemical Society (2017-03-29)The photoconversion efficiency of perovskite solar cells (PSCs) is enhanced by the deposition of inorganic nanoparticles (NPs) at the interface between the compact TiO2 electron-selective contact and the mesoporous TiO2 ... -
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 ... -
Recombination reduction on lead halide perovskite solar cells based on low temperature synthesized hierarchical TiO2 nanorods
Royal Society of Chemistry (2016)Intensive research on the electron transport material (ETM) has been pursued to improve the efficiency of perovskite solar cells (PSCs) and decrease their cost. More importantly, the role of the ETM layer is not yet fully ... -
The Swift Surge of Perovskite Photovoltaics
American Chemical Society (2013)The breakthrough early 1990s dye sensitization of mesoscopic TiO2 films along with a regenerative iodide redox couple led to the explosive growth of dye-sensitized solar cell (DSC) research. The pioneering work of Grätzel ... -
Theory of Impedance and Capacitance Spectroscopy of Solar Cells with Dielectric Relaxation, Drift-Diffusion Transport, and Recombination
American Chemical Society (2014-07)Semiconductor photovoltaic devices currently investigated, such as hybrid organic–inorganic lead halide perovskite based solar cells, have shown a high dielectric polarization combined with ambipolar carrier transport. In ... -
Trend of Perovskite Solar Cells: Dig Deeper to Build Higher
American Chemical Society (2015-06)Using solar energy efficiently to produce electricity has been the subject of intensive research because of the rapid increase of global energy demand and the need to reduce the emission of greenhouse gases from electricity ...
