This method includes simulating for at least one combination of a topology of a photovoltaic cell group, an internal cell temperature(s) and a cell irradiation(s), a model of the photovoltaic cell group to provide a representative current-voltage characteristic curve, and clustering the current-voltage characteristic curves to identify at least one plurality of similar current-voltage characteristic curves. The method also includes generating a many-to-one mapping in the database to map query requests corresponding to each of the at least one plurality of similar current-voltage characteristic curves onto a single representative current-voltage characteristic curve for that plurality, each query request identifying a topology of a photovoltaic cell group, at least one internal temperature for the photovoltaic cells in the photovoltaic cell group and at least one cell irradiation for the photovoltaic cells in the photovoltaic cell group.

Abstract: A PV module is described with an array of PV cells whereby the module is reconfigurable, allowing different configurations to be applied after installation and during operation, i.e. at run-time. The run time configuration of the module has controllable devices. The main controllable devices are any of (individually or in combination): a) switches which determine the parallel/series connections of the cells as well as hybrid cases also. b) switches between the cells and local dc/dc converters and/or among the DC/DC converters; c) actively controlled bypass diodes placed in order to allow excess current to flow in the occurrence of a mismatch.

Abstract: A system and method of simulating device aging based on a digital waveform representative of a workload of an electronic device are disclosed. In one aspect, the method comprises grouping contiguous sets of cycles into segments, each set corresponding to a segment. Each segment has values for a combination of segment parameters that are unique from each of the other segments and a start point that is separated from a start point of an adjacent segment by a pre-defined distance criterion. Grouping the sets into the segments comprises, for each segment: sampling one or more sequential cycles of the workload, generating the segment based on the sampled contiguous cycles having a period exceeding a threshold period, and determining the values for the combination of segment parameters. The method further comprises applying an aging model to the segments to simulate the aging. The segments are a representation of the digital waveform.

Abstract: A plasmonic device comprising an odd number of at least three input waveguides and at least one output waveguide is disclosed. In one aspect, the waveguides are adapted for guiding a surface plasmon polariton wave and the input waveguides are connected to the output waveguide at a waveguide junction. The inserted SPP waves have a phase at the waveguide junction which is either a first phase or a second phase. The second phase is shifted over π with regard to the first phase and a combined SPP wave at the waveguide junction has a resulting phase wherein the dimensions of the waveguides are such that for different combinations of phases of the inserted waves the combined waves are phase aligned.

Abstract: A method is provided for calculating a performance of a photovoltaic module comprising at least a first photovoltaic cell and a second photovoltaic cell. The method comprises calculating a heat flow between the first photovoltaic cell and the second photovoltaic cell using a first thermal equivalent circuit of the first photovoltaic cell and a second thermal equivalent circuit of the second photovoltaic cell, wherein at least one node of the first thermal equivalent circuit is connected to a corresponding node of the second thermal equivalent circuit by a thermal coupling resistance.
