Market-driven EFG modules. Annual subcontract report, 14 December 1995--13 December 1996
- ASE Americas, Inc., Billerica, MA (United States)
This report summarizes the progress made at ASE Americas Inc. during the first year (Phase I) of the planned 3 year program in Phase 4A2 on the development of technology to address its photovoltaic module manufacturing flexibility and cost reduction for its products. This program focusses on advancing manufacturing technology to reduce the thickness of EFG wafers from 300 to 250 microns, to raise EFG solar cell efficiency to be able to produce cells with average efficiency of 15.5% on 10 cm x 10 cm area wafers, and to simplify processes and reduce costs in interconnect and module manufacturing. This work includes the development of a novel and new environmentally safe and reduced cost diffusion glass removal process for the solar cell manufacturing line. The overall goal of the program is to reduce EFG module manufacturing costs by 25%. Module cost reductions of approximately 7% can be identified as a result of successes on the program in the first year. The work in Phase I has been subdivided into efforts in three areas: Task 1: Wafers, Task 2: Cells, and Task 3: Modules.
