Chemical hardness engineering boosts perovskite tandem efficiency to 30.3%

Chinese scientists push all-perovskite solar cell efficiency past 30%

Chinese scientists have pushed perovskite tandem solar cells past the critical 30 percent efficiency mark after developing a new way to control how the materials crystallize during manufacturing. The research team was led by Ge Ziyi, PhD, and Liu Chang, PhD, from the Ningbo Institute of Materials Technology and Engineering (NIMTE), under the Chinese Academy of Sciences (CAS). The team hit a certified power conversion efficiency of 30.3 percent i…

Chemical hardness engineering boosts perovskite tandem efficiency to 30.3%

All-perovskite tandem solar cells are promising candidates for next-generation photovoltaics, as they harvest sunlight more efficiently than single-junction devices and can be fabricated through low-temperature solution processing. However, their performance is often limited by asynchronous crystallization in multicomponent perovskite films, in which different parts of the system crystallize at different times. This leads to compositional and st…

Molecular Templating Boosts Perovskite Solar Stability

In the relentless pursuit of pushing solar energy technology to unprecedented heights, perovskite solar cells have emerged at the forefront of next-generation photovoltaics, promising high efficiency and low-cost production. However, a significant challenge has dogged their scalability and commercial viability: reverse-bias instability, which threatens long-term device reliability when modules are subjected to adverse operating conditions.
