This study demonstrates, for the first time, the successful integration of cyanate into a perovskite solar cell to develop a cutting-edge triple-junction perovskite/Si tandem solar cell,proving cyanates to be viable substitute for halides in perovskite-based solar cells. An efficiency of 27.1 percent was achieved.
The records are around the 35%-40% range in a lab. So this doesn’t actually shatter records.
But if this is something that can be easily manufactured and can impact commercial / residential, then sure, this might be interesting.
Unfortunately, this study is paywalled, and the abstract avoids getting into practical implications.
That’s why I said as written. I didn’t have specs on hand. But again, 2% would be big still
