摘要

The purpose of this study was to develop diffusion welding variables for the joining of silicon solar cells to metal electrical interconnects by laboratory experimentation. Diffusion welding electrical interconnects to silicon solar cells can be accomplished at pressures above 2000 psi and temperatures above 250C without the aid of an inert or protective atmosphere. The high residual stress associated with the mismatch in coefficients of thermal expansion between the solar cell and the interconnect is the cause for cell cracking upon cooling from the welding temperature and weld damage due to thermal cycling. When Kovar interconnects, or copper interconnects inserted between Kovar interconnects, are used, the residual stress in the cell is reduced and cells survive the welding and cooling cycle. Accelerated thermal cycling does not cause major damage to the diffusion welds on solar cell-interconnect assemblies that use Kovar as an interconnect material. 52 refs., 50 figs., 15 tabs.
