Perovskite-silicon tandem cells offer one of the surest pathways to much higher solar efficiencies, one that has moved close to commercialization in the past few years. Much of the work getting to this stage has naturally focused on developing a viable perovskite top cell. Optimizations to the silicon layer underneath, however, will also be important to the overall device function and efficiency. Scientists in Germany examined five different silicon cell concepts similar to those in mass production today, finding that with a few optimizations these could reach efficiencies up to 30.4%.Tandem solar ...Den vollständigen Artikel lesen ...
