ANU researchers set solar record with next-gen cells

Researchers from the Australian National University (ANU) have broken new ground in solar cell energy efficiency and in the process provided a glimpse of the technology’s future. The researchers have a set a new record of 21.6 per cent efficiency, the highest ever achieved for perovskite cells above a certain size. This means 21.6 per cent … Read more ANU researchers set solar record with next-gen cells

Treating solar cell materials reveals formation of unexpected microstructures

Recent advances in solar cell technology use polycrystalline perovskite films as the active layer, with an increase to efficiency of as much as 24.2%. Hybrid organic-inorganic perovskites are especially successful, and they have been used in optoelectronic devices including solar cells, photodetectors, light-emitting diodes and lasers. But the surface of hybrid perovskites is prone to … Read more Treating solar cell materials reveals formation of unexpected microstructures

‘Self-healing’ polymer brings perovskite solar tech closer to market

A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), report scientists from the Okinawa Institute of Science and Technology Graduate University (OIST). Adding a “self-healing” polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong … Read more ‘Self-healing’ polymer brings perovskite solar tech closer to market

Secrets of fluorescent microalgae could lead to super-efficient solar cells

Microalgae are probably the oldest surviving living organisms on the planet. They have evolved over billions of years to possess light harvesting systems that are up to 95 per cent efficient. This enables them to survive in the most extreme environments, and adapt to changes our world has seen over this time-span. Unravelling how this … Read more Secrets of fluorescent microalgae could lead to super-efficient solar cells
