Optimized microsystems-enabled photovoltaics
| DWPI Title: System for designing microsystems-enabled photovoltaic cell for converting portion of light into electric energy in e.g. solar power system in semiconductor fabrication application, has component for computing values for parameters |
| Abstract: Technologies pertaining to designing microsystems-enabled photovoltaic (MEPV) cells are described herein. A first restriction for a first parameter of an MEPV cell is received. Subsequently, a selection of a second parameter of the MEPV cell is received. Values for a plurality of parameters of the MEPV cell are computed such that the MEPV cell is optimized with respect to the second parameter, wherein the values for the plurality of parameters are computed based at least in part upon the restriction for the first parameter. |
| Use: System for designing a MEPV cell for converting a portion of available light into electric energy in an electric power generation system e.g. solar power system, wind power system and geothermal power system, in a semiconductor fabrication application. |
| Advantage: The system provides optimization of the parameter to be beneficial in connection with enhancing efficiency of the MEPV cells. The system uses low quality wafers/inexpensive substrates to create highly efficient cells if contacts are close together. The system provides enhanced maximization effect in current due to enhanced back reflection. |
| Novelty: The system has an analysis component for computing respective values for a set of parameters of a microsystems-enabled photovoltaic (MEPV) cell such that the cell is optimized with respect to objective parameters, where interrelationships include an interdependence among cell efficiency, SRH lifetime and substrate thickness such that cell efficiency rises with substrate thickness in regimes of substrate thickness and SRH lifetime and the cell efficiency, SRH lifetime, separation between collection electrodes and substrate thickness are included on a list of selectable parameters. |
