Polymer-templated nucleation and crystal growth of perovskite films for solar cells with efficiency greater than 21%

Controlling the crystallization process of perovskite films is crucial to obtaining high efficiency in perovskite solar cells. Bi et al. propose the use of poly(methyl methacrylate) as a template for the controlled nucleation and growth of perovskite crystals achieving efficiency of 21.6%.

Solar reduction of carbon dioxide on copper-tin electrocatalysts with energy conversion efficiency near 20%

Solar-driven carbon dioxide reduction has witnessed a renaissance in the past decades, but the system suffers from low reaction rates. Here the authors develop a copper/tin-oxide electrocatalyst, achieving a new benchmark solar-to-CO energy conversion efficiency in a flow electrolyzer.

11% efficiency solid-state dye-sensitized solar cells with copper(II/I) hole transport materials

Inadequate pore infiltration and low conductivity of hole transporter materials limit the performance of solid-state dye-sensitized solar cells. Using fast charge-exchange Cu(II/I) complexes as part of the hole transporting material, Caoet al. overcome these issues to achieve a record photoconversion efficiency of 11%.

Ionic polarization-induced current–voltage hysteresis in CH₃NH₃PbX₃ perovskite solar cells

The origin of hysteresis remains an open question in lead-halide perovskite solar cells. Here, Meloni et al. investigate the causes of hysteresis using an experimental and computational approach, finding that the observed hysteresis is due to halide ion-vacancy movement in the perovskite.
