Glass-glass encapsulation, low-iron tempered glass, and anti-reflective coatings improve light management, durability, and efficiency. Advances in glass compositions, including rare-earth doping and low-melting-point oxides, further optimize photon absorption and conversion. . This chapter examines the fundamental role of glass materials in photovoltaic (PV) technologies, emphasizing their structural, optical, and spectral conversion properties that enhance solar energy conversion efficiency. NGA volunteers update Glass Technical Papers (GTPs) through the systematic review ballot process on a 5-year cycle. . There are other solar cell technologies available in the market with potential use for building-integrated photovoltaic applications; however, they are still under development stages. Efficiencies should increase, as well as long-term stability, and fabricated dimensions. We begin with a discussion of glass requirements, specifically composition, that enable. . ermal collectors. Despite the certification having been explicitly developed for solar thermal applications, it became widely used in the PV module industry, even though the results are not transferable. . Researchers from Aalto University in Finland demonstrated a proof-of-concept of laser-processed glass to be used as a type of solar concentrator for building integrated PV (BIPV) applications.
