Article Abstract
Insufficient interface conformity is a challenge faced in hybrid organic-silicon heterojunction solar cells because of using conventional pyramid antireflection texturing provoking the porosity of interface. In this study, we tested alternative textures, in particular rounded pyramids and inverted pyramids to compare the performance. It was remarkably improved delivering 7.61%, 8.91% and 10.04% efficiency employing conventional, rounded, and inverted pyramids, respectively. The result was interpreted in terms of gradually improving conformity of the Ag/organic/silicon interface, together with the gradually decreasing serial resistance. Altogether, the present data may guide further efforts arising the interface engineering for mastering high efficient heterojunction solar cells.

Increasing atmospheric carbon dioxide concentration necessitates innovative approaches to transform CO into valuable compounds utilizing solar energy. The photocatalytic CO reduction reaction (PC CRR) offers a sustainable solution, yet wide band gaps, rapid electron-hole recombination, and poor CO adsorption capacity limit traditional metal oxide semiconductors for the PC CRR. This review systematically evaluates recent engineering advances in metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) as efficient photocatalysts for the PC CRR.

Herein, a fluoroalkyl side chain modified A-DA'D-A small molecule acceptor, Y18-F9, was developed to optimize the bulk heterojunction morphology in organic solar cells. The introduction of fluorocarbon chains promotes self-assembly into nanoscale fibrous networks, while the low surface energy drive favorable vertical phase segregation. These synergistic effects lead to enhanced molecular packing, improved charge transport and collection, and reduced recombination losses.

Hydrogen evolution reaction (HER) driven by solar energy has attracted considerable attention due to its outstanding efficiency, environmental compatibility, and sustainability. Regrettably, the sluggish progress of the HER and the limitations in charge separation efficiency impede its practical photocatalysis. Herein, a two-step electrostatic self-assembly approach is adopted to construct NiO/CdMnS/TiCT (NO/CMS/TCT) ternary heterojunction with bidirectional carrier channels for boost photogenerated separation and oriented carrier accumulation.

A simple solvothermal method was used in this paper. ZnCoS (ZCS) nanoparticles were smoothly synthesized by this method and loaded on the external surface of MnCd0S (MCS) to form an S-scheme heterojunction. A comparative evaluation was performed with two other single catalysts, and the compound catalyst MCS/ZCS achieved great gain in the process of catalytic action of H generated under sunlight.
