Silicon evolution

China’s policy cracking down on oversupply and cheap, low-quality products, due to come into effect in 2027, sets higher minimum standards and is expected to push module manufacturers to advance their R&D efforts. Some manufacturers are already using their existing crystalline silicon lines to produce perovskite-silicon tandem cells, while others are exploring opportunities in back-contact production. InfoLink’s Hardy He tracks the emerging technological pathways to higher efficiencies and healthier competition.
