Neutral Ligand Triggered Low-Dimensional Reconstruction for Improving the Efficiency and Stability of Perovskite Solar Cells.

Perovskite solar cells (PSCs) offer a potentially large-scale method for producing low-cost renewable energy. However, stability challenges currently limit their practical application. Consequently, alternative methods for increasing the PSC stability are urgently needed.

Structurally colored semitransparent perovskite solar cells using one-step deposition of self-ordering microgel particles.

Semitransparent perovskite solar cells (STPSCs) have excellent potential for widespread application as building integrated photovoltaics. Widespread application of STPSCs could result in decreased CO footprints for buildings. Unfortunately, STPSCs tend to have poor aesthetic qualities (being usually red-brown in color) and low stability.

Using Soft Polymer Template Engineering of Mesoporous TiO Scaffolds to Increase Perovskite Grain Size and Solar Cell Efficiency.

The mesoporous (meso)-TiO layer is a key component of high-efficiency perovskite solar cells (PSCs). Herein, pore size controllable meso-TiO layers are prepared using spin coating of commercial TiO nanoparticle (NP) paste with added soft polymer templates (SPT) followed by removal of the SPT at 500 °C. The SPTs consist of swollen crosslinked polymer colloids (microgels, MGs) or a commercial linear polymer (denoted as LIN).
