Abstract
  • A method for manufacturing high-quality thin film solar cells entirely by the Pulsed Electron Deposition (PED) is presented. The solar cell is a multi-layer architecture composed with an absorber layer with a chalcopyrite structure and the general composition Cu (In, Ga, Al) (Se, S)2 or CIGASS, deposited on a metallic substrate, that is the lower electrical contact or \"back contact\", by one or more buffer layer(s) and a layer acting as an electrical contact or the higher \"top contact\". The novelty of this process are: 1) The absence of layers containing cadmium (Cd) in the solar cell; 2) The deposition of the absorber layer, of the buffer layer(s) and of the top ohmic contact can be made sequentially using the same high-energy electron pulsed system, alternating only the target where the beam focuses and the energy of the electron beam. Main applications: The method described in the patent can be useful in the photovoltaic field, in particular for the fabrication of \"2nd generation solar cells\" or thin film solar cells. Main Advantages: The novelties introduced in this patent are: 1) Ability to deposit every layer using the same pulsed electron source. 2) Capability to deposit the absorber layer (CIGASS) using a single stage. 3) Ability to grow cadmium-free buffer layers, resulting in a totally eco-compatible solar cell.
