Tuning the Optical and Structural Properties of Halide Perovskite by PbS Quantum Dot Additive Engineering for Enhanced Photovoltaic Performances
(Wiley, 2024)
The combination of inorganic PbS quantum dots (QDs) and lead halide perovskite in one nanocomposite is considered as a promising approach to overcoming the limitations of metastable perovskites. However, to date, only a ...
Analysis of the Hysteresis Behavior of Perovskite Solar Cells with Interfacial Fullerene Self-Assembled Monolayers
(American Chemical Society, 2016-10)
The use of self-assembled monolayers (SAMs) of fullerene derivatives reduces the hysteresis of perovskite solar cells (PSCs). We have investigated three different fullerene derivatives observing a decrease on hysteresis ...
Photon Up-Conversion with Lanthanide-Doped Oxide Particles for Solar H2 Generation
(American Chemical Society, 2014-05)
Up-conversion (UC) of infrared (IR) photons into visible radiation constitutes a promising strategy to enhance the light harvesting efficiency of photovoltaic and photoelectrochemical devices. In the present study, we ...
Influence of the substrate on the bulk properties of hybrid lead halide perovskite films
(Royal Society of Chemistry, 2016-10)
In addition to the known effect of the substrate on the interfacial properties of perovskite films, here we show that the bulk properties of hybrid lead halide perovskite films depend on the type of substrate used for film ...
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. ...
Core/Shell Colloidal Quantum Dot Exciplex States for the Development of Highly Efficient Quantum-Dot-Sensitized Solar Cells
(American Chemical Society, 2013)
Searching suitable panchromatic QD sensitizers for expanding the light-harvesting range, accelerating charge separation, and retarding charge recombination is an effective way to improve power conversion efficiency (PCE) ...
High reduction of interfacial charge recombination in colloidal quantum dot solar cells by metal oxide surface passivation
(The Royal Society of Chemistry, 2015)
Bulk heterojunction (BHJ) solar cells based on colloidal QDs and metal oxide nanowires (NWs) possess unique and outstanding advantages in enhancing light harvesting and charge collection in comparison to planar architectures. ...
General Working Principles of CH3NH3PbX3 Perovskite Solar Cells

Organometal halide perovskite-based solar cells have recently realized large conversion efficiency over 15% showing great promise for a new large scale cost-competitive photovoltaic technology. Using impedance spectroscopy ...
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 ...
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 ...
