Cracks in perovskite films for solar cells easily healed, study finds
PROVIDENCE, R.I. [Brown University] — A new study reveals good news for the possibility of using perovskite materials in next-generation solar cells. The study, published in the journal Acta Materialia, finds that though perovskite films tend to crack easily, those cracks are easily healed with some compression or a little bit of heat.
