Korean researchers build back-contact perovskite solar cells with lower recombination losses
The research team developed the perovskite solar cell with a spin-coated bilayer tin oxide electron transport layer that boosts charge extraction, achieving a 4.52% efficiency and improved stability.
Oleic acid anti‑soiling coating for solar modules
Researchers in Türkiye have developed a passive anti-soiling coating for PV panels using oleic acid–modified aluminum oxide nanoparticles applied via spray coating. Laboratory and field tests showed the coating reduced dust accumulation and initially boosted daily energy output, though performance declined under prolonged environmental stressors.
AI platform aims to transform solar site assessment
Learnewable uses AI-based insights to detail local solar opposition before developers invest time or energy in projects.
