What are Photovoltaic Coatings, Adhesives, Sealants and Elastomers?
These materials are engineered to protect solar cells from environmental stresses, enhance light capture, and secure mechanical integrity. Coatings provide anti‑reflective or UV‑blocking layers; adhesives bond encapsulants, glass, and busbars; sealants seal edges and joints against moisture; elastomers add flexibility and thermal resilience, especially for bifacial or flexible modules.
