An environmental failsafe for lead-based perovskites
Scientists in Switzerland discovered that certain types of phosphate salt react with lead only in the presence of moisture, to form non-water-soluble phosphates. Incorporating these salts into the architecture of a lead-based perovskite solar cell could greatly reduce the risk of lead seeping into the environment should the cells be damaged, without incurring significant costs or negatively affecting the cell’s performance.
Russian scientists send organic PV into orbit
Scientists at Russia’s Skoltech Institute of Science and Technology have demonstrated a solar cell with record high radiation stability. The scientists say the cells, based on an organic polymer compound, could be a strong candidate to meet the requirements of powering satellites in lower earth orbit.
