en.Wedoany.com Reported - Hanwha Qcells will lead a nationwide project supported by the South Korean government, dedicated to commercializing next-generation high-efficiency tandem solar modules.

The project, named "Development and Demonstration of Commercial-Area Perovskite/Silicon Tandem Modules," is managed by the Korea Institute of Energy Technology Evaluation and Planning (KETEP) under the Ministry of Climate, Energy and Environment. Hanwha Qcells leads a consortium of eight other South Korean companies, research institutions, and universities, commencing a three-year R&D effort starting this April.

The project aims to demonstrate commercial-area tandem modules with an efficiency of at least 28% and an area exceeding 1.7 square meters. Tandem cells improve power generation efficiency by absorbing different bands of sunlight, with a theoretical maximum efficiency of 44%, approximately 1.5 times higher than the 29% of conventional silicon cells.

Hanwha Qcells will focus on developing tandem manufacturing technologies suitable for mass production, planning to align this R&D project with tandem pilot lines already operating in South Korea and Germany, accumulating demonstration data, gradually establishing a foundation for mass production technology, with a commercialization target set for 2029.

Moon Soo-jin, head of Hanwha Qcells' Pangyo R&D Center, stated that the company will accelerate the commercialization process of tandem technology while contributing to enhancing the global competitiveness of South Korea's solar industry ecosystem.
