  • Patent number: 10693021
    Abstract: A method of passivating a silicon substrate for use in a photovoltaic device, comprising providing a silicon substrate having a bulk and exhibiting a front surface and a rear surface, and forming by liquid phase application a dielectric layer on at least said rear surface. The dielectric layer formed at the rear surface is capable of acting as a reflector to enhance reflection of light into the bulk of the silicon substrate, and the dielectric layer is capable of releasing hydrogen into the bulk as well as onto a surface of the silicon substrate in order to provide hydrogenation and passivation. The present invention provides an inexpensive, low cost method of improving the electrical and/or optical performance of photovoltaic devices through the application of coating chemicals onto the backside of the silicon substrate.

  • Patent number: 10686400
    Abstract: A solar PV module is disclosed having two types of laterally-separated coplanar cells with different bandgaps to improve conversion efficiency. A diffracting entrance window directs sunlight with wavelengths shorter than a separation 5 wavelength ks is directed largely to the first type of wider bandgap cells. Sunlight with wavelengths longer than a separation wavelength ks is directed largely to the second type of narrower bandgap cells. The separation wavelength is chosen so that each cell is illuminated largely by that part of the solar spectrum to which it has the higher conversion efficiency, resulting in an overall conversion efficiency higher than 10 for either type of cell used alone. The wider bandgap cells are configured on a planar support in separated parallel strips, with the narrower bandgap cells largely filling the area between these strips.

    Abstract: Methods, systems, and computer program products for cognitively predicting dust deposition on solar photovoltaic modules are provided herein. A computer-implemented method includes deriving, with respect to solar photovoltaic modules, dust parameters from image data, and estimating, for a given future time at a current module orientation, an amount of surface area of the modules that will be covered by dust and a yield loss of the modules associated with dust coverage. The method also includes forecasting, for the given future time at each of one or more modified module orientations, an amount of surface area of the modules that will be covered by dust and a yield loss of the modules associated with dust coverage. Further, the method includes generating an instruction to change the orientation of at least one of the modules, and outputting the instruction to at least one actuation system associated with the modules.

  • Patent number: 10673379
    Abstract: A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. Removing a defective solar cell from a super cell may be difficult, however. It may therefore be advantageous to bypass defective solar cells in a super cell rather than remove and replace them. A bypass conductor may be applied to the rear surface of the super cell to bypass one or more defective solar cells in a super cell or in a solar module comprising super cells.
