Sulfonium cations for quasi-2D perovskite solar cells

Ruddlesden-Popper-type (RP) quasi-two-dimensional (2D) perovskite solar cells (PSCs) have attracted extensive attention due to their unique photovoltaic properties and excellent device stability. Due to disordered crystallization, ...

Optimizing efficient perovskite photovoltaics

Developing low-cost and stable metal electrodes is crucial for mass production of perovskite solar cells (PSCs). As an earth-abundant element, Cu becomes an alternative candidate to replace noble metal electrodes such as ...

First single-crystal organometallic perovskite optical fibers

Due to their very high efficiency in transporting electric charges from light, perovskites are known as the next generation material for solar panels and LED displays. A team led by Dr. Lei Su at Queen Mary University of ...
