Light-Trapped, Interconnected, Silicon-Film(TM) Modules: Annual Technical Status Report, 18 November 1995 - 18 November 1996

AstroPower is developing a module-manufacturing technology based on a film-silicon technology. AstroPower, as a Technology Partner in the Thin-Film PV Partnership, is employing its Silicon-Film(TM) technology to develop an advanced thin-silicon-based product. This module will combine the design and process features of the most advanced thin-silicon solar cells with light-trapping. These cellswill be integrated into a low-cost interconnected array. During the second year of the 3-year project, AstroPower's emphasis was on developing key submodule fabrication processes. Key results of the work include developing a new thin-film growth concept process based on attaching the low-cost substrate to the thin silicon layer after film growth; developing a new technique to achievelight-trapping in thin layers of silicon based on pigmented high-temperature glass materials; and developing key submodule fabrication processes, including contact grid design, subelement isolation, and screen-printed interconnection.
