Research from the University of New South Wales indicates that the process used to treat copper-plated contacts in heterojunction solar cells significantly impacts their mechanical stress, strain, and microscopic structure. According to a study in Solar Energy Materials and Solar Cells, a team from UNSW and SunDrive Solar examined how different annealing conditions affect copper, indium tin oxide, and silicon layers in these cells.
The scientists compared letting samples settle at room temperature with a fast annealing method at approximately 200 degrees Celsius for 45 seconds. Analysis showed that rapid annealing reduced the copper lattice parameter but increased the lattice parameter and a specific width measurement in the underlying indium tin oxide layer. This process also raised microstrain levels in both the copper and the indium tin oxide.
Mechanical stress mapping in the silicon revealed zones of high local stress along the copper contacts, which were more pronounced in the fast-annealed samples compared to those left at room temperature. The research suggests that promoting a specific crystalline texture in the plated copper and minimizing defects can help lower the stress transferred to the silicon and indium tin oxide layers.
The findings point to a preference for room-temperature treatment when comparable contact adhesion is possible, as it better preserves the desired copper crystal orientation and limits thermal strain. This work follows other recent investigations by UNSW teams into factors affecting heterojunction solar cell durability, including environmental degradation and soldering materials.
