Abstract:
1. A method of making a doped semiconductor junction for use in an electronic device comprising: (a) forming a first polycrystalline semiconductor layer in-situ doped with donors or acceptors over a substrate such that the first doped semiconductor layer has a first polarity, the first layer including colloidal semiconductor nanoparticles, comprising: (b) forming a second layer in contact with the first semiconductor layer over a substrate to form the semiconductor junction; and (c) performing a second anneal of the deposited in-situ doped colloidal semiconductor nanoparticles, either before or after forming the second layer, whereby the in-situ doped colloidal semiconductor nanoparticles are fused so that a continuous doped semiconductor layer is formed.
