    摘要: A solar cell photovoltaic device using ultrathin films of polycrystalline silicon and deep uneven surface structures is disclosed. According to one embodiment, the uneven structures include one or more pits having a depth of at least 10 microns. According to another embodiment, the uneven structures include one or more cones or columns having a height or at least 10 microns. Because the unevenness of the structures, the photovoltaic device is able to use a very thin layer of polycrystalline silicon to effectively trap and absorb light.
