Scientists in China found that capsaicin, the natural compound responsible for a chili pepper’s spicy flavor, can also act as a ‘secret ingredient’ in perovskite solar cells, making them both more efficient and stable. The group added capsaicin to the precursor materials of a common perovskite, leading to dramatic improvements in the resulting solar cell.
European renewables, including Spanish solar, made big gains as energy demand recovered before the second wave of Covid infections. Nuclear was a notable loser, in part because clean energy volumes in the north of the continent drove down power prices sufficiently to make reactors uncompetitive.
Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.
Sweden was set to replace its rebate scheme with unspecified tax breaks by the end of this year, but the government has instead decided to allocate another $31.5 million for 2021 – for enterprises and municipalities only.
Researchers have modeled the effects of various PV module arrangements on a greenhouse used for rose growing in Iran’s Shiraz region. The team determined a ‘sweet spot’ where modules produced the most energy and provided optimal growth conditions for the crop.
Through this new project, the Swedish CIGS turnkey equipment supplier aims to expand its presence in southern European PV markets.
According to its creator, Swedish start-up Evolar, the new technology can be applied to existing production lines for crystalline silicon modules and increase a product’s efficiency by around 5%.
Swedish scientists have developed a redox flow battery with polymer electrodes, based on a special conductive polymer known as PEDOT. The battery features a water-based electrolyte based on a solution of redox quinone molecules, which can be extracted from forest-based materials.
