Under the "dual carbon" strategy, China's photovoltaic (PV) industry has achieved remarkable innovation, fostering the development of high-efficiency cell technologies and diverse application scenarios. In 2024, the PV sector is witnessing a surge in cutting-edge technologies such as HJT, BC, and perovskite, heralding a new era of technological advancement.
HJT Technology
Heterojunction (HJT) technology offers exceptional efficiency, bifacial power generation, low power temperature coefficients, and reduced degradation. In recent years, breakthroughs in upstream materials have significantly reduced costs. For instance, KEEs' stable supply of silver-coated copper paste has addressed cost concerns, while industry leaders leverage patented technologies like 0BB cells and ultra-thin silicon wafers for mass production. Analysts predict HJT's growth will reshape the PV industry, driving capacity upgrades and strengthening its global competitiveness.
BC Technology
Back Contact (BC) cells are regarded as the pinnacle of crystalline silicon efficiency. Their grid-free front design enhances both aesthetics and energy output. BC technology integrates with other cell types like TOPCon and HJT, further boosting efficiency. Market leaders such as LONGi and Aiko have launched BC products, with experts forecasting BC's market share to reach 30-40%. This technology is poised to support diversified applications and sustainable industry growth.
Perovskite Technology
Perovskite is celebrated as the leader of third-generation PV technology, boasting high efficiency, strong low-light performance, and simple processes. Its tandem structures promise conversion efficiencies exceeding 45%. Recent breakthroughs in stability mark a significant milestone. By 2027, perovskite is expected to achieve large-scale production, unlocking potential across sectors like IoT, EVs, and aerospace, while accelerating the transition to renewable energy.
These advanced technologies represent a promising future for the PV industry, offering innovative pathways for sustainable and high-quality development.
