Title: High volume method of making low-cost, lightweight solar materials

Abstract

A thin film solar cell and a method fabricating thin film solar cells on flexible substrates. The method includes including providing a flexible polymeric substrate, depositing a photovoltaic precursor on a surface of the substrate, such as CdTe, ZrTe, CdZnTe, CdSe or Cu(In,Ga)Se.sub.2, and exposing the photovoltaic precursor to at least one 0.5 microsecond to 10 second pulse of predominately infrared light emitted from a light source having a power output of about 20,000 W/cm.sup.2 or less to thermally convert the precursor into a crystalline photovoltaic material having a photovoltaic efficiency of greater than one percent, the conversion being carried out without substantial damage to the substrate.

  • A dish-shaped, radiant energy collector comprises a thin, concave, thermoplastic cover having a reflective layer of metallization vapor deposited on the convex side thereof. A coating of foamed resin is applied to the metallization in order to render the collector self-supporting. Struts or a layer of honeycomb cardboard and/or fiberglass may be introduced into the sandwiched composite to provide further structural rigidity. The cover is produced by forming a flat sheet of acrylic plastic which is transparent to the wavelengths of interest.
  • A semiconductor device is described having a substrate, a conductive intermediate layer deposited onto said substrate, wherein the intermediate layer serves as a back electrode, an optical reflector, and an interface for impurity gettering, and a semiconductor layer deposited onto said intermediate layer, wherein the semiconductor layer has a grain size at least as large as the layer thickness, and preferably about ten times the layer thickness. The device is formed by depositing a metal layer on a substrate, depositing a semiconductive material on the metal-coated substrate to produce a composite structure, and then optically processing the composite structure bymore » illuminating it with infrared electromagnetic radiation according to a unique time-energy profile that first produces pits in the backside surface of the semiconductor material, then produces a thin, highly reflective, low resistivity alloy layer over the entire area of the interface between the semiconductor material and the metal layer, and finally produces a grain-enhanced semiconductor layer. The time-energy profile includes increasing the energy to a first energy level to initiate pit formation and create the desired pit size and density, then ramping up to a second energy level in which the entire device is heated to produce an interfacial melt, and finally reducing the energy to a third energy level and holding for a period of time to allow enhancement in the grain size of the semiconductor layer. 9 figs.« less
