When it comes to clean energy, solar power is a shining example of hope and new ideas. As we keep looking for better ways to use the sun's energy, a groundbreaking study has shed new light on the possibilities of solar cells. This study is based on a cutting-edge substance called lead halide perovskite-based colloidal quantum dots (PQDs), which was a potential but little-studied area of solar technology up until now. On the other hand, what do scientists find when they switch their attention from inorganic to organic PQDs? It turns out that the answer is a big improvement in how well solar cells work.
