Abstract: Glass covers, which are integral parts of solar modules, cause a ~4% reflection loss which reduces overall efficiency. Transmission is also inhibited by the accumulation of dust particles. In this thesis, anti-reflective glass which is also anti-dust has been fabricated. A non-lithographic method has been developed to create random nanostructures on the glass surface. It was observed that the nano-patterning improved transmission of planar glass for a wide 120&176; range of incidence angles. Improvement of 1% in power conversion efficiency was also observed in solar modules packaged with the glass. After 3 months of outdoor testing, the difference was even greater due to the anti-dust property (2% reduction in efficiency for standard modules versus only 0.3% for modules with the nano-patterned glass). Thus, antireflective and self-cleaning glass can show significant improvement in efficiency of fixed-mount solar module installations, and may play a greater role in future photovoltaic applications.
