Standardizing Measurements for Perovskite Solar Cell Stability
EPFL scientists introduce a data-driven proposal for standardizing the measurements of perovskite solar cell stability and degradation. Their work aims to create consensus in the field and overcome one of the major hurdles on the way to commercializing perovskite photovoltaics. Perovskite solar cells are an attractive alternative to silicon solar cells due to their high power-conversion efficiencies (over 22%) and lower capital expenditure and manufacturing costs. One of the greatest obstacles is stability. To be commercially viable, perovskite solar cells must also be able to maintain their efficiency over time, meaning that they must not degrade significantly over 25 years of service.
