  • Patent number: 11214867
    Abstract: A showerhead for vacuum deposition of several species, the showerhead being divided into several quarters containing each at least one outlet for the species, each of the quarter defining the wall of an underlying compartment containing at least one species, wherein two adjacent compartments contains different species. A process for vacuum deposition of one or more species onto a substrate, including providing a substrate for thin film growth in a growth chamber, providing two or more species to be effused towards the substrate, effusing the two or more species towards the substrate with line of sight propagation and in high vacuum conditions, and obtaining a thin film with gradients of chemical elements composition, morphology or crystalline phase.

  • Patent number: 9036389
    Abstract: A system for controlling photovoltaic electricity production equipment having photovoltaic modules each equipped with a DC/DC microconverter connected to a DC bus, a DC bus manager, and an inverter for converting the direct current from the photovoltaic panels into alternative current intended for an electrical distribution network. Power is injected into the DC bus when the voltage of the DC bus is less than a minimum voltage until the minimum voltage is reached. Each of the microconverters injects a maximum power from the photovoltaic modules into the DC bus when the voltage of the DC bus is between a first voltage and a second voltage. The injecting of power from the photovoltaic modules into the DC bus is stopped when the voltage of the DC bus is less than a low threshold voltage or greater than a high threshold voltage.
