A team of researchers from the UK and Japan has found that the tiny defects which limit the efficiency of perovskites - cheaper alternative materials for solar cells - are also responsible for structural changes in the material that lead to degradation.
A group of researchers from the UK and Japan has actually located that the tiny issues which limit the efficiency of perovskites-- more affordable alternative materials for solar cells-- are also in charge of architectural modifications in the material that result in degradation.
Perovskite photovoltaics are cheaper to produce but lose performance over the years. To make them sustainable, they need to at least last a decade.
