Storage solution heralds breakthrough for perovskite solar cells

Tests carried out by the researchers, from Sheffield University’s Energy Institute and Department of Physics and Astronomy found that storing perovskite precursor solutions at low temperatures increases their durability extensively.

According to the University, this development could potentially make the manufacture of perovskite solar cells more efficient, as the process would require fewer batches of more stable material to be produced, saving time, reducing material waste and also allowing device yield and efficiency to be optimised.

Perovskite solar cells are fabricated using simple solution-based techniques similar to those used in the printing industry and companies looking to commercialise perovskite solar cells are thinking about the best ways to manufacture at high volume.

In a statement, Professor David Lidzey, from Sheffield University’s Department of Physics and Astronomy, said: “If a company cannot produce large volumes of precursor solutions and be able to rely on them performing consistently, it further complicates the manufacturing process. We have shown that this problem can be side-stepped by storing such materials at low temperature.”
