However, the interfacial contact between perovskite film and TNRAs is one of the main factors that restricts the power conversion efficiency (PCE) of TNRAs based PSCs at present. In this paper, by employing a two-step spin-coating method, the influence of PbI2 solvent such as PbI2/DMSO +...

Deposition of perovskite films by antisolvent engineering is a highly common method employed in perovskite photovoltaics research. Herein, we report on a general method that allows for the fabrication of highly efficient perovskite solar cells by any ant
high efficiencyperovskitesolar cellssolvent assistanceTo replace or reduce toxic solvents in perovskite solar cell (PSC) manufacturing,2-Methyltetrahydrofolate (2-MTHF), as an important raw material for organicsynthesis and an excellent solvent, is incorporated in PSCs as an additivecosoluble precursor...
“The material is dirt cheap,” says Michael Grätzel, who is famous within the solar industry for inventing a type of solar cell that bears his name. His group has produced the most efficient perovskite solar cells so far—they convert 15 percent of the energy in sunlight into...
Poly (3-hexylthiophene) (P3HT) is one of the most attractive hole transport materials (HTMs) for the pursuit of stable, low-cost, and high-efficiency perovskite solar cells (PSCs). However, the poor contact and the severe recombination at P3HT/perovskite interface lead to a low power convers...
A group of chemists from Kaunas University of Technology (KTU), Lithuania synthesized materials that were used for constructing a record-breaking perovskite solar module, with an efficiency of 21.4 percent. This was achieved ...
solid-state perovskite solar cell in 2012, perovskite solar cells based on lead halide perovskites having organic cations such as methylammonium CH3NH3PbI3or formamidinium HC(NH2)2PbI3have received great attention because of superb photovoltaic performance with power conversion efficiency exceeding 22%...
