  • Patent number: 11302839
    Abstract: A design for a micro-lens (i.e., a lens on the scale of micrometers) incorporates existing nanofabrication techniques and can be incorporated into High Concentrating Photovoltaic (HCPV), solar thermal collectors, and traditional flat PV systems. Using the theory of wave optics, the design is able to achieve a high numerical aperture, i.e., it can receive light over a wider range of angles. The design also reduces the distance the focal point shifts as the light source shifts; this eliminates the need for a tracking system in CPV and PV applications. Reducing the lens size also facilitates smaller, lightweight CPV systems, which makes CPV attractive for additional applications. Finally, these concentrators reduce the exchanging area of a typical flat solar thermal system where heat is received, which improves the overall system's efficiency and allows its use also during rigid winter time.

    Abstract: A photovoltaic system's configuration specification can be inferred by an evaluative process that searches through a space of candidate values for the variables in the specification. Each variable is selected in a specific ordering that narrows the field of candidate values. A constant horizon is assumed to account for diffuse irradiance insensitive to specific obstruction locations relative to the photovoltaic system's geographic location. Initial values for the azimuth angle, constant horizon obstruction elevation angle, and tilt angle are determined, followed by final values for these variables. The effects of direct obstructions that block direct irradiance in the areas where the actual horizon and the range of sun path values overlap relative to the geographic location are evaluated to find the exact obstruction elevation angle over a range of azimuth bins or directions. The photovoltaic temperature response coefficient and the inverter rating or power curve of the photovoltaic system are determined.

  • Patent number: 11132024
    Abstract: An electronic device having a battery assembly is disclosed. Unlike traditional battery assemblies that include rectilinear electrodes with two sides of equal length, the battery assemblies described herein may include electrodes having a shape/configuration resembling an L-shape electrode used to form chemical reactions in order to generate electrical energy. However, other shapes/configurations are possible. The shape/configuration of the housing of the battery assembly confirms to the shape/configuration of the electrodes. Further, in order to accommodate an internal component (such as a circuit board assembly), the shape of the battery assembly provides additional space in the electronic device. In order to form the electrodes, the electrodes may undergo a die cutting operation. Also, the housing may include a channel, or reduced dimension, that accommodates a flexible circuit in the electronic device that passes over the battery assembly at the channel.

  • Patent number: 11070167
    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.
