On July 24, a research team from Soochow University, led by Professors Yang Xinbo and Zhang Xiaohong, made significant strides in the industrialization endeavor of next-generation photovoltaic cells. Working in collaboration with The Hong Kong Polytechnic University and multiple photovoltaic companies, the team successfully created an indium-free composite layer material. This innovation involved the construction of a 'molecular bridge' connecting perovskite and crystalline silicon, thereby substantially enhancing both the photoelectric conversion efficiency and the long-term stability of tandem photovoltaic cells. The team's pertinent discoveries were featured in the esteemed international academic journal Nature Energy on the same day.

As per reports, the tandem photovoltaic cell, conforming to an industrial standard size of 207.9 cm², developed by the team, achieved a certified photoelectric conversion efficiency of 30.6%. Moreover, it retained over 95% of its initial efficiency even after enduring continuous operation for 1000 hours in environments characterized by high temperature and humidity. Presently, this accomplishment has advanced to the pilot-scale amplification stage, with corporate production lines striving to mass-produce larger-area tandem photovoltaic cells to further evaluate their performance.
