Perovskite Solar Cells Skip Yellow Phase, Degrade Slower Thanks to Key Additives

Halide perovskites are gaining ground on silicon as a critical material for solar cell technologies: A new study published in the journal Science reports a method to make perovskite-based photovoltaics more durable, allowing the films to attain the desirable black phase of crystal configuration quicker and at lower temperatures while also making it harder to degrade into the inactive yellow phase. Perovskites are solution-processable materials and can be readily processed as a solution or dep...
