ceramic vacuum filter for perovskite in romania

video researchers push limits of perovskite solar cell performance

jun 15 when the ink is dried it leaves behind a thin film that crystallizes on top of the glass that when graetzel and his team apply their new vacuum flash technique creates seeds for crystal formation leading to very regular shiny highly conductive perovskite crystals with increased photovoltaic yields
