Bulky additives could make cheaper solar cells last longer

https://techxplore.com/news/2024-01-bulky-additives-cheaper-solar-cells.html

"preventing perovskite semiconductors from degrading quickly... 2X - 4X cheaper than today's thin-film solar... bulky defect pacifying molecules increase hardness, stability and lifespan... bulky molecules forced larger perovskite grains reducing grain boundaries' density... heating to >200°C confirmed bulky additives helped retain more of their slate black color and develop fewer structural defects... size and configuration important when designing additives... improve lifetime perovskite solar cells, LEDs and photodetectors"
