摘要
据英国《自然》杂志网站近日报道，尽管薄膜太阳能电池应用广泛，但其也有“先天不足”：薄膜越薄．制造成本越低，但当其变得更薄时，会失去捕光能力。美国科学家表示，当薄层厚度等于或小于可见光的波长时，其捕光能力会变得很强。科学家们可据此研制出厚度仅为现在商用薄膜太阳能电池厚度的1％、但捕光能力却大有改善的薄膜太阳能电池。
Thin-film solar cells are plagued by diminishing returns： thinner panels are cheaper to make, but as the semiconductor layer gets thinner it loses its light- trapping ability. Researchers at the Califomia Institute of Technology in Pasadena now report the secret to making thin layers more absorbent -- making it possible to use layers up to 100 times thinner than those in the commercial devices available today.
