Researchers at the National University of Singapore (NUS) have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 percent across a solar energy absorption area of 1 sq cm. This achievement marks the highest

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.
