Vital Materials Across the PV Module
See how our products support engineered layers throughout the photovoltaic stack, from substrates and encapsulants to absorber interfaces and conductive coatings.
Functional Layers We Support Within the PV Module Stack
Cover Glass
Provides environmental protection and maximizes transmission into the active semiconductor layers.
Encapsulants
Protect PV cells from moisture, thermal cycling, and mechanical stress; maintain optical clarity over the module lifetime.
Solar Cell Layer
Active semiconductor layer where light absorption and charge generation occur; supported by Vital’s absorber powders, targets, and granules.
Backing Substrate
Structural layer delivering mechanical stability and long-term durability.
Core Materials for Photovoltaic Module Manufacturing
Transparent Conductive Oxides (TCOs)
High-quality transparent electrode materials optimized for light transmission, sheet resistance, and uniform current collection.
Photovoltaic Glass Ink & PV Welding Materials
Specialized formulations for patterning, interconnection, and metallization of solar glass surfaces.
Glass additives for Module Light Management and Reliability
Additives engineered to improve module transparency, UV durability, thermal stability, and mechanical strength in high-exposure environments.
Absorber Powders and Pellets
High purity organic and inorganic powders and pellets for perovskite thin-film absorber and Cadmium based absorber with optimized optical absorption and electronic extraction.
Targets & granules
Materials used for sputtering and deposition of absorber layers, charge transport layers and back contact in thin-film PV, supporting uniformity, adhesion and high conversion efficiency.
Buffer Layer Targets and Materials
Engineered materials for interface optimization that enhance charge separation, reduce recombination, and stabilize semiconductor junctions. Including metal, metal oxide and organic materials.
Precursor Liquid and Special Gas
High purity metalorganic source materials and special gas for charge transport layer and capping layers, ensuring dense and uniform thin-film deposition
