Wide ranging photovoltaic laminates comprising particulate semiconductors

Abstract
A photovoltaic laminate of different semiconductor layers for providing a wide range of photovoltaic characteristics. One of the layers is an amorphous semiconductor and at least one other of the layers is of crystalline particles. Additional semiconductor layers, both amorphous and non-amorphous, may be included. The amorphous layers have a thickness of about a few microns and the crystalline layers have a thickness above about 60 microns. The various semiconductor layers can include P, N and intrinsic regions. In accordance with a method aspect of the invention, the particulate layers are produced by blowing a molten semiconductor through a nozzle or by the spin coating of emulsions. The particles are desirably accompanied by a binder in the form of a silicate, an acrylic or a cycloaliphatic epoxy.
