Abstract: A method of producing photovoltaic cells with the μ-tandem architecture based on crystalline silicon substrates and quantum dots, ensuring both effective and stable operation of the entire tandem system as well as high absorption in the spectral range from UV to MIR and operation in scattered and incident light conditions at different angles, acting as an anti-reflective layer. A further purpose of the invention is to develop a new structure of a μ-tandem photovoltaic cell based on microcrystalline silicon (Si) layers and a layer of nanometric semiconductor structures with a core-shell architecture such that the resulting structures work as a tandem cell with the characteristics of micro-cells, connected together in its lower part.

Abstract: A method for manufacturing laminar layered photovoltaic panel and a laminar layered photovoltaic panel manufactured with the method. The method includes placing a previously chemically strengthened glass pane in the process chamber of a magnetron device and subject to the ion cleaning process, coating the top surface of the glass pane with a titanium layer using a magnetron sputter deposition method, and onto the uniform titanium layer, ceramic overprints of nanoparticles reproducing refined building material aggregates are made with the use of printing nozzles to obtain an array of micro-objects in the form of toroids, then imeerzing the glass pane in a water solution of hydrofluoric acid and subject to the electrochemical process. The glass pane is placed in a furnace for a thermal fixing process and bound with a float glass pane by lamination with the use of a polymer lamination films having photovoltaic cells.
