HIGH EFFICIENCY SILICON SOLAR CELLS.
Abstract
Five hundred P(+)/N and five hundred N(+)/P cells have been fabricated on a pilot line basis. There was a 70% yield of P(+)/N cells having a 100 mW/sq cm sunlight efficiency of 11.4% or greater. There was a 70% yield of N(+)/P cells having a 100 mW/sq cm sunlight efficiency of 10.1% or greater. Preliminary measurements indicate a substantial increase in efficiency for both cell types at solar intensities of approximately 300 mW/sq cm, due to the specific design of these cells for operation at these intensities, thus showing good performance for operation in systems utilizing solar concentrators. Comparisons are made between the pilot line N(+)/P and P(+)/N cells; and between these cells and commercially available production cells of both polarities. Cost estimates are given on the basis of the yields obtained. (Author)
