A Safer Lead Based Perovskite Solar Cell

March 25, 2020 | Leave a Comment

Northern Illinois University researchers are reporting on a potential breakthrough in the development of hybrid perovskite solar cells. The scientists developed a technique to sequester the lead used to make perovskite solar cells and minimize potential toxic leakage. Working with the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, the […]

Fixing Perovskite Film Cracks Made Easy

March 18, 2020 | Leave a Comment

A new Brown University study found that cracks in brittle perovskite films can be easily healed with compression or mild heating. This is a good sign for the use of perovskites in next-generation solar cells. The study, published in the journal Acta Materialia, found that though perovskite films tend to crack easily, those cracks are […]

The Hunt For Perovskite Solar Cell Efficiency Gets Results

December 12, 2019 | 1 Comment

A Helmholtz-Zentrum Berlin (HBZ) für Materialien und Energie team has demonstrated that hybrid halide perovskites crystallize without an inversion center. Interactions between the organic molecules and adjacent iodine atoms can lead to the formation of ferroelectric domains, which, indirectly, can result in higher solar-cell efficiencies. The formation of these ferroelectric domains cannot occur in purely […]

Solution Found For Perovskite Solar Cell Defects

November 14, 2019 | Leave a Comment

Rice University materials scientists have found inorganic compounds quench defects in perovskite-based solar cells and expand their tolerance of light, humidity and heat. The scientists believe they’ve overcome a major hurdle keeping perovskite-based solar cells from achieving mainstream use. Through the strategic use of the element indium to replace some of the lead in perovskites, […]
