Glass-Glass PV Modules

Glass-Glass module designs are an old technology that utilises a glass layer on the back of modules in place of traditional polymer backsheets. They were heavy and expensive allowing for the lighter polymer backsheets to gain the majority of the market share at the time. However, despite these disadvantages, the ITRPV[2] predict an increase in
