ABSTRACT:
A process for fabricating solar to electrical energy conversion units, includes the forming of arrays of parallel-connected strings of series connected solar cells selected from a number of different categories of cells. The categories are defined by different ranges of cell currents at a set cell voltage, a set level of incident cell face radiation and a set temperature. Each string of an array consists of cells from the same category; but strings of cells from different categories are used in the same array. A goal array current range for the arrays may be correlated with the average current of a group of cells at the set conditions, or with the estimated average for a group of cells to be manufactured, so that a selected number of strings for the arrays multiplied by such average falls within the range. According to a particular fabricating process, nine solar cell categories covering a total of approximately 0.9 amperes are established to form arrays of six parallel-connected strings of eleven series-connected solar cells having a goal array current range of 12.95 amperes plus or minus 2.2 percent. According to this particular process, hundreds of string combinations are possible, including combinations having strings from the lowest and highest categories.
