Researchers at Chonnam National University introduced a nanometer‑scale germanium oxide (GeOₓ) interlayer between the molybdenum back contact and the tin monosulfide (SnS) absorber, addressing deep‑level defects, sodium diffusion, and MoS₂ formation. The 7 nm GeOₓ layer improves SnS grain uniformity and charge transport, raising power‑conversion efficiency from 3.71 % to 4.81 %, one of the highest reported for vapor‑deposited SnS cells. The vapor‑transport deposition method is compatible with scalable thin‑film manufacturing. The study also suggests the interface strategy could benefit a range of thin‑film electronics.

Researchers at the University of Delaware have converted discarded corn cobs and other agricultural residues into high‑performance biochar filters. In laboratory trials, the optimized biochar removed up to 64 % of dissolved ammonia and more than 97 % of polystyrene micro‑ and...
Hebrew University researchers have created a flexible, semi‑transparent perovskite solar cell that can be color‑tuned for use in windows and curved surfaces. The device achieves up to 9.2% power‑conversion efficiency while maintaining about 35% visible transparency. Light transmission and hue...
Researchers at the Chinese Academy of Sciences and Zhengzhou University have demonstrated flexible perovskite solar modules exceeding 20 % efficiency by using sulfuric‑acid‑treated single‑walled carbon nanotube (SWCNT) films as ITO‑free window electrodes. The acid treatment raises conductivity and creates a NiSO₄–NiOₓ...
Researchers led by Dr. Tian Carey have unveiled a predictive framework that links in‑plane versus out‑of‑plane stiffness to successful electrochemical exfoliation of 2D materials. The model identified dozens of new semiconducting nanosheets, enabling the fabrication of printed transistors, digital‑to‑analogue converters...
A team at Chalmers University has demonstrated a photocatalytic system that uses conjugated polymer nanoparticles to split water into hydrogen under simulated sunlight, eliminating the need for expensive platinum. By engineering hydrophilic, loosely packed polymer chains, the particles achieve a...
Researchers at the Korea Institute of Energy Research introduced CO Adsorption‑Induced Deposition (CO AID), a carbon‑monoxide‑driven method that forms 0.3 nm platinum shells on low‑cost metal cores. The technique reduces catalyst fabrication time to 30 minutes‑2 hours at kilogram scale, far faster than...
Researchers at Guangxi University unveiled micro‑nano reconfigurable robots (MNRM) that capture and release carbon dioxide using sunlight as an energy source. In laboratory tests the robots sequestered 6.19 mmol CO₂ per gram of sorbent and regenerated at just 55 °C, maintaining over...
Researchers at the University of Surrey have replaced indium tin oxide (ITO) with single‑walled carbon nanotube (SWCNT) films in flexible perovskite solar modules, achieving over 20% power‑conversion efficiency on large areas and a record 24.5% on small cells. A sulfuric‑acid...
