    摘要: A back contact integrated photovoltaic cell includes a substrate having a dielectric surface and a patterned metal layer with parallel spaced alternately positive and negative electrode fingers forming an interdigitated two-terminal structure over the dielectric surface of the substrate. A dielectric filler may be in the interstices of separation between adjacent spaced parts of the patterned metal layer. Parallel spaced strips, alternately of p+ doped polysilicon and of n+ doped polysilicon, may top the positive and negative interdigitated electrode fingers, respectively, and form doped p-type active regions and n-type active regions of the integrated photovoltaic cell, spaced and isolated by a strip of undoped or negligibly doped polysilicon. An n− or p− doped or intrinsic semiconducting layer of at least partly crystallized silicon, forming a semiconductor region of thickness adapted to maximize absorption of photonic energy when illuminated by sunlight, may cover the interdigitated active doped regions.

    摘要: A method for forming an interface free layer of silicon on a substrate of monocrystalline silicon is provided. According to the method, a substrate of monocrystalline silicon having a surface substantially free of oxide is provided. A silicon layer in-situ doped is deposited on the surface of the substrate in an oxygen-free environment and at a temperature below 700° C. so as to produce a monocrystalline portion of the silicon layer adjacent to the substrate and a polycrystalline portion of the silicon layer spaced apart from the substrate. The silicon layer is heated so as to grow the monocrystalline portion of the silicon layer through a part of the polycrystalline portion of the silicon layer. Also provided is a method for manufacturing a bipolar transistor.
