A study led by the University of Oxford has identified a novel semiconductor that overcomes a key limitation with light-harvesting materials. The results, published today (28 Oct) in Nature, could enable more efficient solar panels with higher outputs. Solar energy currently…
Researchers at Chiba University identified a thermodynamic boundary for photocurrent generation in organic solar cells and found that more rigid donor molecules were associated with lower radiative voltage losses. Organic solar cells have long promised lightweight, flexible and potentially low-cost…
Researchers in China have developed an acid-free method to recover silver wires from end-of-life aluminum back-surface-field solar cells using a molten mixture of sodium hydroxide and potassium hydroxide (NaOH-KOH). The molten salt etches the cell’s silicon nitride (SiNx) passivation layer…
Indian researchers used neem extract to grow silver-decorated titanium oxynitride photoanodes, boosting quasi-solid-state dye-sensitized solar cell efficiency by 54.7 percent. This substitution matters enormously for real-world deployment Conventional liquid-electrolyte cells suffer from evaporation, leakage, and temperature instability, which have prevented them…
A hydrothermally synthesized TiO2 microsphere scattering layer in bilayer photoanodes raised short-circuit current and efficiency in dye-sensitized solar cells, with the best N3-sensitized device reaching 1.59 percent efficiency. The bottom layer uses commercial TiO2 nanoparticles (P25), which the authors describe as ensuring improved dye…
Researchers have found a method that significantly improves the efficiency of organic solar cells. Nations worldwide are accelerating the deployment of renewable energy infrastructure to meet strict climate regulations. Despite this green ambition, the manufacturing of most clean energy technologies…
A new molecular locking strategy could help overcome the efficiency, stability, and scalability challenges in organic solar cells (OSCs). Organic solar cells offer lightweight, flexible, carbon-based alternatives to silicon and offer vast potential for commercial use. But the cells’ delicate…
Scientists have developed a molecular bonding method that could make flexible organic solar cells more efficient and durable, addressing two obstacles that have limited their wider use. The new design achieved 20.4% power conversion efficiency in small laboratory cells and 18.8% active-area…
