Silicon solar cell process development, fabrication and analysis. Phase I. Annual report, June 15, 1978-June 15, 1979

PDF Version Also Available for Download.

Description

This program has investigated, developed and utilized technologies appropriate and necessary for improving the efficiency of solar cells made from various unconventional silicon sheets. During this reporting period, work has progressed in fabrication and characterization of solar cells from RTR ribbons (Motorola), EFG (RF and RH) ribbons (Mobil-Tyco), dendritic webs (Westinghouse), Silso wafers (Wacker), cast silicon by HEM (Crystal Systems), silicon on ceramic (Honeywell) and continuous Czochralski ingots (Hamco). Solar cells were fabricated using a standard process typical of those used currently in the silicon solar cell industry. Also back surface field (BSF) processing and other process modifications were included ... continued below

Description

This program has investigated, developed and utilized technologies appropriate and necessary for improving the efficiency of solar cells made from various unconventional silicon sheets. During this reporting period, work has progressed in fabrication and characterization of solar cells from RTR ribbons (Motorola), EFG (RF and RH) ribbons (Mobil-Tyco), dendritic webs (Westinghouse), Silso wafers (Wacker), cast silicon by HEM (Crystal Systems), silicon on ceramic (Honeywell) and continuous Czochralski ingots (Hamco). Solar cells were fabricated using a standard process typical of those used currently in the silicon solar cell industry. Also back surface field (BSF) processing and other process modifications were included to give preliminary indications of possible improved performance. The parameters measured included open circuit voltage, short circuit current, curve fill factor, and conversion efficiency (all taken under AMO illumination). Also measured for typical cells were spectral response, dark I-V characteristics, minority carrier diffusion length, and photoresponse by fine light spot scanning. The results were compared to the properties of cells made from conventional single crystalline Czochralski silicon with an emphasis on statistical evaluation. Limited efforts were made to identify growth defects which will influence solar cell performance and discussion is given on the difficulties experienced in processing the sheets using near-conventional methods.
