New Publication from the SUNLAB: Progress in Photovoltaics


SUNLAB researchers, including lead author PhD candidate Gavin Forcade, in collaboration with researchers at the Université de Sherbrooke, the French Commissariat à l’énergie atomique et aux énergies alternatives (CEA) and in part supported by collaborators from STACE, recently published new results in Progress in Photovoltaics. They investigated an antireflection coating consisting of a monolayer of close-packed silica microbeads partially submerged within a polydimethylsiloxane (PDMS) encapsulant, for concentrator photovoltaic (CPV) submodules. Comparing to a commercialized SiOx encapsulant for a reference 500x CPV submodule, they measured a 2.6% higher short-circuit current. In addition, they performed a series of simulations and predicted further improvements up to 3.4% for smaller beads with a deeper submergence.

This work demonstrates the ability of the microbeads/PDMS encapsulant to improve the performance of present CPV modules, thereby promoting further study to incorporate the encapsulant commercially.
