Key Application Scenarios
LANGYI's functional materials deliver proven performance across the full photovoltaic value chain -- from module packaging to cell-level optimization.
Scenario 01
Photovoltaic Module Packaging Materials
Encapsulants and adhesive films that protect PV cells from moisture, UV degradation, and mechanical stress over a 25+ year service life.
EVA Encapsulant Film Additives
Cross-linking agents and UV stabilizers that enhance EVA film adhesion, optical clarity, and long-term weatherability in laminated modules.
POE Film Functional Modifiers
Specialty compatibilizers and nucleating agents for polyolefin elastomer encapsulant films, improving moisture barrier and PID resistance in bifacial modules.
Edge Sealant & Butyl Tape Compounds
High-performance inorganic nano-fillers that reinforce edge-seal butyl formulations, reducing water vapor transmission and preventing delamination at module perimeters.
Backsheet Adhesion Promoters
Water-based curing agents and surface coupling chemicals that improve adhesion between polymer backsheets and encapsulant layers, ensuring structural integrity under thermal cycling.
Scenario 02
Surface Protection of Photovoltaic Modules
Coating and treatment solutions that preserve optical transmittance, resist soiling, and withstand harsh outdoor environments for maximum energy yield.
Anti-Soiling & Self-Cleaning Coatings
Hydrophilic nano-silica and specialty chemical functional materials that form low-surface-energy coatings on glass surfaces, repelling dust and enabling rain-assisted self-cleaning to maintain peak transmittance.
Anti-Reflective Coating Formulations
Inorganic micro-nano particles engineered for sol-gel AR coating processes, reducing front-glass reflectance to below 1% and boosting module short-circuit current density by up to 3%.
UV-Resistant Protective Coatings
Advanced polymer-based UV absorbers and HALS stabilizers applied to module frames and junction boxes, preventing photodegradation and chalking under prolonged UV exposure in high-irradiance climates.
Scenario 03
Performance Optimization of Photovoltaic Cells
Functional materials that directly enhance cell conversion efficiency, reduce recombination losses, and extend operational lifetime at the semiconductor level.
Passivation Layer Precursors
High-purity inorganic nano-materials used in PERC and TOPCon passivation stacks to reduce surface recombination velocity and improve open-circuit voltage (Voc) in crystalline silicon cells.
Conductive Paste Functional Additives
Carbon-silicon based functional materials incorporated into silver and aluminum pastes to improve contact resistance, sintering behavior, and ohmic junction quality on cell metallization lines.
Texturization & Etching Chemical Agents
Specialty chemical functional materials used in acidic and alkaline texturization processes for mono and multi-crystalline silicon, creating optimized pyramid surface structures that maximize light trapping and reduce reflectance.
Encapsulant-Cell Interface Coupling Agents
Water-based curing agent systems that strengthen the chemical bond at the encapsulant-to-cell interface, suppressing potential-induced degradation (PID) and improving damp-heat performance per IEC 61215 standards.
