Squeezing a rock-star material could make it stable enough for solar cells – Science Daily
A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to…
Among the materials known as perovskites, one of the most exciting is a material that can convert sunlight to electricity as efficiently as today’s commercial silicon solar cells and has the potential for being much cheaper and easier to manufacture.There’s just one problem: Of the four possible atomic configurations, or phases, this material can take, three are efficient but unstable at room temperature and in ordinary environments, and they quickly revert to the fourth phase, which is completely…
