What Is the Future of Photovoltaic Cells?

Many researchers think that peroskit photovotaic cells will be the successor of silicon, really. Cheaper to manufacture because the lower temperature and a higher potential conversion efficiency than silicon. But there's a big downside. The life span ive sto when they get, when they reats. Soin a couple of months ago, the researchers published a study where they they had a perovsky that was stable up to 51 thousand hours of continuous sunlight - which is now on the 20 year indistres dayth.
