First Central China Perovskite & Tandem Solar Cells Industrialization Forum Officially Launched in Wuhan

Driven by rapid technology and project deployment, the perovskite sector is accelerating industrialization while facing common challenges including technical routes, industry standards, service life and capital investment. Benefiting from policy support, strong academic research and a complete industrial chain, Central China is emerging as a key growth pole for the industry. To seize opportunities for large-scale application, the First Central China Perovskite & Tandem Solar Cells Industrialization Forum will be held in Wuhan from June 10 to 12, 2026, connecting industrial resources nationwide.

Amid the wave of photovoltaic innovation, perovskite technology has achieved remarkable efficiency breakthroughs via tandem structures, leading the industry toward higher efficiency and lower costs. It is reshaping the development landscape of photovoltaics and powering the future of green energy.

Perovskite and Tandem Structures: The Core Path to High-Efficiency Photovoltaics

As a front-runner of third-generation photovoltaic technology, perovskite solar cells are centered on perovskite-structured materials and have risen rapidly since their first application in 2009. Featuring a tunable bandgap ranging from 1.15 eV to 3.06 eV, their theoretical conversion efficiency far exceeds that of conventional crystalline silicon (c-Si) cells. The certified lab efficiency has reached 27.2%, and tandem devices have surpassed 34.6%. With low-cost and facile fabrication advantages, perovskite has become a highly promising next-generation photovoltaic technology for commercialization.

Tandem solar cells act as an efficiency multiplier for photovoltaics. By stacking semiconductor materials with different bandgaps, they make full use of photons across the solar spectrum, enabling highly efficient light-to-electricity conversion. Among various combinations, the perovskite/c-Si tandem stands out prominently: the perovskite top cell efficiently absorbs short-wavelength light, while the c-Si bottom cell excels at utilizing long-wavelength light. This synergy breaks the efficiency bottleneck of single-junction cells, positioning tandem technology as a core development direction for future photovoltaics.

Core Application Scenarios: Diversified Empowerment for Green Development

Thanks to excellent transparency, light weight and high performance under low-irradiance conditions, perovskite solar cells have achieved breakthroughs in multiple fields:

• Building-Integrated Photovoltaics (BIPV): Integrated into curtain walls and rooftops to combine power generation and architectural aesthetics;
• Automotive Photovoltaics: Lightweight and radiation-resistant properties enable self-powered vehicles and extended cruising range;
• Indoor Photovoltaics: Strong low-light performance provides long-term power for Internet of Things (IoT) devices;
• Space Exploration: Stable power supply for satellites and space probes.

AiJiang Technology: Pioneering Perovskite In-Line Inspection to Break Industrialization Bottlenecks
