A Structurally Simple Polymer Donor Enables High-Efficiency Organic Solar Cells with Minimal Energy Losses.
Angew Chem Int Ed Engl

Energy loss (Eloss) between optical energy gap (Eg) and open-circuit voltage (eVoc) sets efficiency upper limits for organic solar cells (OSCs). Nevertheless, further breaking the limit of Eloss in OSCs is challenging, especially via structurally simple materials in binary OSCs. Herein, a structurally simple non-halogenated polymer donor, namely PBDCT, is developed for realizing high-efficiency OSCs with record-breaking Eloss.

The photoelectrochemical properties of hematite-based photoanodes are hindered by severe carrier recombination and poor reaction activity, which is a major challenge. Herein, we coupled zirconium-doped α-FeO (Zr:FeO) and phosphating cobalt molybdate electrocatalyst (P-CoMoO) to ameliorate the above difficulties. The conductivity and carrier density of hematite significantly increase by Zr doping.

Seed priming with NaCl improved the tissue tolerance nature in moderately salt-tolerant cultivar Anuradha under salt stress. Is an improved tissue tolerance in primed chickpea seedlings supplemented with a boosted antioxidant response? To investigate, a seed priming experiment with sub-lethal salt concentration (50 mM NaCl) was performed with chickpea cv. Anuradha.

The cytochrome b6f complex (Cyt b6f) plays pivotal roles in both linear and cyclic electron transport of oxygenic photosynthesis in plants and cyanobacteria. The four large subunits of Cyt b6f are responsible for organizing the electron transfer chain within Cyt b6f and have their counterparts in the cytochrome bc1 complex in other bacteria. The four small subunits of Cyt b6f are unique to oxygenic photosynthesis, and their functions remain to be elucidated.

Developing ideal photocatalysts for energy regeneration and environmental remediation by combining the advantages of individual semiconductors remains a significant challenge. Herein, tungsten trioxide (WO)/CuSnS S-scheme heterojunction composite photocatalysts are developed. Initially, doped oxygen vacancy (OV) was prepared on two-dimensional WO nanosheets by direct calcination method.
