摘要
A photovoltaic device includes a crystalline substrate having a first dopant conductivity, an interdigitated back contact and a front surface field structure. The front surface field structure includes a crystalline layer formed on the substrate and a noncrystalline layer formed on the crystalline layer. The crystalline layer and the noncrystalline layer are doped with dopants having an opposite dopant conductivity from that of the substrate. Methods are also disclosed.
