“An international team of researchers has brought a new generation of solar cells a step closer to commercialisation, by showing how sunlight can trigger a ‘healing process’ in the cells to improve their efficiency and stability.

The new research—led by Swinburne in collaboration with Wuhan University of Technology in China, the University of Melbourne, and the University of Adelaide—shows how ‘doping’ the cells with a performance enhancing chemical, that is triggered by sunlight, improves their stability, making them a better prospect for commercialisation.

The new type of solar cells, known as perovskite solar cells, are …”
