The photovoltaic (PV) sector is undergoing a transformative wave of innovation, with perovskite and N-type battery technologies emerging as dual engines of progress. In Xuzhou, a 200MW perovskite tandem cell production line built by GCL-Poly Energy achieved full operational capacity in just 29 days—a record-breaking speed for industrial deployment. The facility’s mass production cells demonstrate 31.27% conversion efficiency, surpassing the theoretical 29.43% limit of traditional crystalline silicon cells while halving production costs, marking a decisive step toward commercialization.
N-type battery technologies are experiencing explosive growth. Data from the China Photovoltaic Industry Association shows TOPCon and HJT cells now command 79% market share as of Q1 2025, with TOPCon modules delivering 2.7% higher energy yield than PERC counterparts under high-irradiance conditions in Changzhou’s summer field tests. Leading enterprises are accelerating capacity expansion: Longi Green Energy announced plans to expand its Malaysian N-type battery production to 8GW by year-end, while Tongwei Group intends to establish a 10GW N-type manufacturing base in Europe targeting global decarbonization markets.
Technological synergy is driving breakthroughs. Back contact (BC) cells—epitomizing advanced crystalline silicon innovation—have achieved 26.6% mass-production efficiency. Aiko Solar’s ABC series modules, featuring 75% bifaciality, deliver 8-12% more energy than conventional panels. In Zhejiang’s Yiwu, Trina Solar’s “PV + storage + hydrogen” integrated project combines BC modules with perovskite technology, reducing levelized cost of energy (LCOE) below ¥0.25/kWh—a 35% improvement over legacy systems.
Energy storage advancements are reinforcing zero-subsidy viability. CATL’s new 325Ah liquid-cooled storage-specific cells reduce system costs to ¥0.8/Wh, while Huawei’s smart string storage solution achieved 92.3% round-trip efficiency in Qinghai’s Golmud hybrid project. These innovations are reshaping sector economics: Shandong’s Zaozhuang “county-wide PV” initiative boosted equity return rates to 9.8% using N-type modules and smart trackers— 3.2% improvement over traditional models.
Capital markets are responding decisively to the tech revolution. In December 2024, perovskite specialist GCL completed a ¥4.5 billion Series C funding round, while Alpha Components secured the first TÜV Rheinland IEC certification for perovskite modules. On the industrial front, Jinko Solar signed a strategic agreement with Saudi Arabia’s ACWA Power to construct a 5GW N-type module plant in the Middle East, paired with Sungrow’s 1.2GWh storage systems, establishing the world’s first “N-type + storage” zero-carbon industrial park.
The China Photovoltaic Industry Association emphasizes the sector’s shift from “scale expansion” to “quality competition.” In Zhejiang’s Haining, Astronergy’s GW-scale copper electroplating line achieved mass production, reducing HJT silver consumption by 80%. Meanwhile, Tongwei’s TNC pilot line in Sichuan’s Panzhihua broke 26.1% efficiency—1.5% above commercial baselines. These milestones signal the imminent arrival of sub-¥0.20/kWh solar power, accelerating global energy transition dynamics.
