Available in PDF, EPUB and Kindle. Book excerpt: Solar cells have been fabricated from unconventional silicon materials in the second and final phase of the contract. In the most recent period of work, EFG, Web, Hem, and Continuous CZ silicon materials were fabricated into solar cells, measured and analyzed. Current-voltage measurements under AM1 conditions, in addition to those under AMO conditions, were introduced in Phase II. Several low-cost fabrication steps were included in that phase. Both Hem and Continuous CZ silicon were found to be superior to what had been provided in Phase I. Correlation between quality of starting materials and cell conversion efficiency was observed for Hem-grown silicon. Correlation between position in the crystal growth sequence and cell quality was observed for Continuous CZ.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in fabrication and characterization of solar cells from EFG ribbons and HEM ingots is reported. EFG ribbons grown in carbon-containing gas atmosphere showed improved sheet quality. This new EFG provided an average baseline cell efficiency of 10.3% under AM1 (as opposed to 8.0% for the earlier EFG). The best efficiency achieved by the advanced process was 13.8% AM1. Evaluation of two ingots from the HEM process indicated that HEM has a problem of inhomogeneity in sheet quality within each of the two ingots studied to data.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar cells have been fabricated from unconventional silicon materials supplied in the Large Area Sheet Task of the Low Cost Solar Array Project. The cells were constructed using methods intended to optimize the efficiency, as well as by a standard method intended to act as a baseline procedure. Following fabrication, all cells have been measured on the Spectrolab Solar Simulator at Air Mass Zero and 28/sup 0/C. Conversion efficiencies are based upon total device area. Maximum conversion efficiency obtained for Kayex continuous CZ material has been 12.4% (optimized), for Crystal Systems HEM material 11.2% (optimized), for Mobil Tyco EFG (RH) 8.4% (baseline) and EFG (RF) 9.8% (baseline), for Westinghouse Web material 12.0% (optimized), for Motorola RTR 7.2% (baseline), and for Wacker Silso 10.6% (baseline). All of these materials are from Phase I of the Contract. Phase II of the contract has started with Mobil-Tyco EFG (RH) material. Following fabrication by the baseline method this material, as well as the others in the program, will be fabricated using low-cost processing methods.

Book excerpt: A program plan, baseline process, measurement program and quality control plan have been generated as enunciated by the contract. Cutting operations have been completed on the Wacker Silso silicon sheet material. The first fabrication run of Wacker Silso polycrystalline silicon into solar cells by the baseline process has been completed. Average conversion efficiency for solar cells fabricated by the baseline process from Wacker Silso sheet and measured at air mass zero was 10.4%, compared with the control cells, fabricated from single crystal CZ silicon, whose average conversion efficiency was 12.2%.
