Flash infrared annealing as a cost-effective and low environmental impact processing method for planar perovskite solar cells
For successful commercialization of perovskite solar cells, straightforward solutions in terms of environmental impact and economic feasibility are still required. Flash Infrared Annealing (FIRA) is a rapid method to ...
Perovskite Photovoltaic Modules: Life Cycle Assessment of Pre-industrial Production Process
(ElsevierCell Press, 2018)
Photovoltaic devices based on perovskite materials have a great potential to become an exceptional source of energy while preserving the environment. However, to enter the global market, they require further development ...
PbS quantum dots as additives in methylammonium halide perovskite solar cells: the effect of quantum dot capping
(Royal Society of Chemistry, 2019-09)
Colloidal PbS quantum dots (QDs) have been successfully employed as additives in halide perovskite solar cells (PSCs) acting as nucleation centers in the perovskite crystallization process. For this strategy, the surface ...
Enhancement of the Performance of Perovskite Solar Cells, LEDs, and Optical Amplifiers by Anti-Solvent Additive Deposition

Halide perovskite derivatives present unprecedented physical phenomena among those materials which are suitable for photovoltaics, such as a fast ion diffusion coefficient. In this paper it is reported how the benefits ...
Operation Mechanism of Perovskite Quantum Dot Solar Cells Probed by Impedance Spectroscopy
(American Chemical Society, 2018)
We fabricated perovskite quantum dot solar cells (PQDSCs) and varied the thickness of the QD layer by controlling the number of deposition cycles; the cells were systematically investigated with impedance spectroscopy. ...
Spray-Pyrolyzed ZnO as Electron Selective Contact for Long-Term Stable Planar CH3NH3PbI3 Perovskite Solar Cells
(American Chemical Society, 2018)
Electron selective contacts (ESCs) play an important role in the performance of perovskite solar cells (PSCs). ZnO has attracted important attention as a good material for ESCs because of its matched energy levels with ...
Deleterious Effect of Negative Capacitance on the Performance of Halide Perovskite Solar Cells
(American Chemical Society, 2017)
Negative capacitance in photovoltaic devices has been observed and reported in several cases, but its origin, at low or intermediate frequencies, is under debate. Here we unambiguously demonstrate a direct correlation ...
