This new approach could lead to a much faster development of new alternatives, says Buonassisi, who was a co-author of that research. While perovskites continue to show great promise, and several companies are already gearing up to begin some commercial production, durability remains the biggest obstacle they face.
Currently, the record PCE of a perovskite solar cell (25.5 %) 9 was achieved with bulk perovskite thin films, whilst the highest PCE of a perovskite nanocrystal solar cell is 16.6 %. 65 The primary reason for this considerable gap in the PCE is the capping agents of the perovskite nanocrystals, that is, oleic acid and oleylamine. The insulating ...

Photovoltaic arrays usually involve solar panels, a collection of dozens or even hundreds of solar cells. Each solar cell contains a semiconductor, usually made of silicon. When the semiconductor absorbs sunlight, it knocks electrons loose. An electrical field directs these loose electrons into an electric current, flowing in one direction.
