Lately I've been preparing the PV silicon cells for final experiment: implementation of silver nanoparticles on the cell front. Parallel to that the suspesions were optimized and the deposition condition were tested. On the field of computer simulation I finished investigation of possible mechanisms that can decrease the yield from plasmonic structres implementation on the Si cell front. There were particles interaction, periodic and random arrangement, two-particle aggregates case, and size distribution. The final experiment is planned in September.
