TaiyangNews Market Survey on Encapsulation Materials & Backsheets 2026

The PV polymer landscape is undergoing a significant transformation, driven by the rapid adoption of advanced cell and module technologies and the industry’s continued focus on balancing cost reduction, reliability, and performance. The materials in focus are encapsulation and backsheets. Reflecting these key drivers, the 6^th edition of TaiyangNews Market Survey on Encapsulation Materials and Backsheets provides a comprehensive overview of these two key polymers. The survey includes responses from 15 companies covering 191 products, comprising 109 encapsulation materials and 82 backsheet products. The survey reemphasizes the growing prominence of encapsulation material. It analyzes market developments, shipment trends, material shares, pricing evolution, and technology-specific material requirements. Particular attention is given to the evolution of encapsulation configurations for TOPCon, BC, and tandem technologies, including the growing adoption of EPE structures, optimized EVA formulations, UV-management solutions, and specialty encapsulants.

In contrast, backsheets continue to lose share as glass-glass module architectures become mainstream. However, the report underscores the relevance of polymer back covers in several applications, including lightweight modules, BC modules, hail-prone regions, and specialized rooftop installations. A couple of backsheet suppliers found a new avenue in the form of a front sheet, which replaced front glass.

The survey includes insights from leading global suppliers as well as India-specific perspectives from both domestic and international companies serving the Indian market. All put together, the survey provides a detailed analysis of how polymer materials are evolving alongside the next generation of PV technologies and manufacturing strategies.
