Summary: This study demonstrates efficient low-temperature flexible perovskite solar cells by improving the interfacial contact between the electron-transport layer (ETL) and the perovskite layer. The incorporation of titanium tetrachloride (TiCl4) effectively decreases the adsorbed oxygen active sites and oxygen vacancies of the flexible tin oxide (SnO2) ETL layer. This leads to improved charge collection efficiency and higher solar cell efficiencies up to 23.7% at 218 K, opening up new possibilities for flexible photovoltaic technology in low-temperature environments.

Summary: CuSCN is a highly stable, easy to fabricate, and efficient hole transport layer. Researchers are using various bilayers to overcome the degradation caused by polar solvents on organic absorber layers. In this study, a bilayer of CuSCN with an ammonia-based aqueous solvent was proposed and exhibits improved surface roughness values and light transmittance. The bilayers also demonstrate good hydrophobic properties and can function well on different architectures. The successful demonstration of these bilayers in Photoluminescence analysis shows their potential in fabricating highly efficient and stable perovskite solar cells.

Summary: This study demonstrates a ternary halogen doping strategy to improve the quality and stability of air-processed all-inorganic CsPbI3 perovskite films. The introduction of CsBr and PbCl2 as halide sources allows Br and Cl to insert into the crystal lattice of the CsPbI3 perovskite, improving its phase stability and regulating the crystallization process to enhance film morphology. By optimizing the doping content, the air-fabricated PSC device based on ternary halogen doping achieves a champion PCE of 17.51% with improved working stability, retaining over 80% of the initial PCE after continuous illumination for 2400 hours.

Summary: A polylactic acid (PLA) modification approach is reported to improve the performance of mixed-halide inorganic perovskites solar cells (PSCs). PLA modification effectively passivates surface defects, induces secondary grain growth, and changes the surface region of perovskite from n- to p-type, resulting in less carrier recombination and lower energy loss. The modified PSCs exhibit high power conversion efficiencies (PCEs) and improved air stability.
