In tests, the engineers showed that adding these layers boosted the efficiency of light conversion by 3.5 times. R2 Bathrooms - Impression Mirror Led Demister Shaver Socket 500x700mm. The team says that doing so creates a kind of mirror that produces reversed images of the electron-hole pairs, which lessens the likelihood of electrons recombining with the holes. The researchers found they were able to drastically reduce electron recombination in perovskite by placing it on a substrate made up of either silver alone, or alternating layers of silver and aluminum oxide. This is what’s known as electron recombination. But sometimes, electrons fall back into the “holes” they left behind, reducing the overall current and as such the efficiency of the material. Perovskites and other photovoltaic materials generate electricity by allowing sunlight to excite electrons in the material, causing them to jump out of their atoms, ready to be guided to generate an electrical current. Instead, the team found that adding a layer of a different material underneath it changed the interactions of the electrons in the perovskite, reducing an energy-sapping process. Now a new study has boosted perovskite’s efficiency by three and a half times, without even tweaking the material itself. But in just the last decade, a new contender has rapidly risen through the ranks – perovskite, which is much cheaper and has already caught up to silicon in efficiency. Now engineers at the University of Rochester have developed a new way to more than triple the material’s efficiency by adding a layer of reflective silver underneath it.įor the better part of a century, silicon has been the go-to material for making solar cells, thanks to its abundance and efficiency in converting light to an electrical current.
