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.Though improvements have come thick and fast in the world of perovskite solar cells, it is still a very young technology with a wealth of possible pathways to further boost efficiency and ensure long-term performance stability, as well as to ...Den vollständigen Artikel lesen ...
