BUFFER LAYER FOR HIGH PERFORMING AND LOW LIGHT DEGRADED SOLAR CELLS

摘要

Methods for forming a photovoltaic device include forming a buffer layer between a transparent electrode and a p-type layer. The buffer layer includes a doped germanium-free silicon base material. The buffer layer has a work function that falls within barrier energies of the transparent electrode and the p-type layer. An intrinsic layer and an n-type layer are formed on the p-type layer. Devices are also provided.

1. A method for forming a photovoltaic device, comprising:
forming a buffer layer between a transparent electrode and a non-crystalline silicon containing p-type layer, the buffer layer including a non-crystalline doped germanium-free silicon base material, wherein the forming of the buffer layer comprises adjusting the deposition power so that a work function of the buffer layer falls within barrier energies of the transparent electrode and the p-type layer; and forming an intrinsic layer and an n-type layer on the p-type layer.
