Scaled-up Perovskite Solar Cells Prove Their Conversion Power - Professor Subodh Mhaisalkar and Associate Professor Nripan Mathews

We are pleased to share the research achievement of Professor Subodh Mhaisalkar, Associate Professor Nripan Mathews and their team, which has been featured in various media.

A research team at NTU has created a 21 cm2 solar cell module made of perovskite with a power conversion efficiency of 18.1 % – the highest reported value for perovskite solar modules so far. Dr Annalisa Bruno, senior scientist at NTU’s Energy Research Institute, said: “Our work demonstrates the compatibility of perovskite technology with industrial processes and its potential for market entry. This is good news for Singapore, which is looking to ramp up the use of solar technology.” Prof Subodh Mhaisalkar, NTU associate vice-president and co-lead author of the paper, said the findings would allow Singapore to harness the power of sunlight more efficiently. The semi-transparent, coloured perovskite solar cells “can be used on facades and windows in skyscrapers, which is not possible with current silicon solar panels as they are opaque and block light”."

The research team has published their findings in the peer-reviewed journal, Joule with the title “Highly Efficient Thermally Co-evaporated Perovskite Solar Cells and Mini-modules”. The research article can be found via this link: https://www.cell.com/joule/fulltext/S2542-4351%2820%2930097-0
