Abstract
A structure for a single junction solar cell. The structure includes a substrate member having a surface region. The structure includes a first electrode structure overlying the surface region of the substrate member. A P absorber layer is formed overlying the first electrode structure. In a specific embodiment, the P absorber layer has a Ptype impurity characteristics and a first optical absorption coefficient greater than 10cmin a wavelength range comprising 400 nm to 800 nm. An Nlayer is provided overlying the P absorber layer and an interface region formed within a vicinity of the P layer and the Nlayer. The structure also includes a high resistivity buffer layer overlying the Nlayer and a second electrode structure overlying the buffer layer.
