‍‍‍Recently, Shenzhen S.C launched its industrial-grade piezoelectric ink-jet printing technology for perovskite film and successfully delivered ink-jet printing equipment. The Company's R&D team addressed the core challenges in mass production of perovskite/crystalline silicon tandem solar cells, and redefined the coating of perovskite film process standards with nanoscale patterning accuracy, high material utilization and multi-substrate compatibility, thereby creating new drivers for the photovoltaic industry to enhance manufacturing yield and expand application scope.

Get Right to the Spot in Tackling the Pains Troubling Industry: Limitations and Breakthroughs in Conventional Process

When it comes to perovskite photovoltaic technology, conventional solution deposition of perovskite film suffers from edge effects, backside solution leakage, and coating challenges on textured Si. The R&D team of Shenzhen S.C’s perovskite pilot line has integrated industrial-grade piezoelectric ink-jet printing technology with a nanoscale ink droplet control system, enabling precise deposition of perovskite ink.

First Core Strength: Nanoscale Patterning Accuracy, Precise Deposition of Perovskite Ink, and Increased Effective Area of Solar Cells

High-precision ink-jet control enables precise deposition of perovskite ink, which prevents material waste and performance loss while significantly increasing the effective power generation area of the solar cells. This method paves the way for breakthroughs in tandem solar cells efficiency.

Second Core Strength: High Material Utilization  

Ink-jet printing technology enables on-demand al of raw materials, which reduces excessive coating and cleaning losses. The overall raw material utilization reaches over 95%, significantly reducing the manufacturing costs of perovskite solar cells.

Third Core Strength: Compatibility with Multiple Substrates to Break into the BIPV Market  

This technology supports various substrates including crystalline silicon, glass, and flexible polymer films in different sizes. It can also be applied to curved surfaces and irregular structures, offering high-efficiency, low-cost perovskite module solutions for Building Integrated PV (BIPV), thereby accelerating the commercialization of green buildings.

Co-Creating the Future of Perovskite Solar Cells Commercialization

A range of ink-jet printer models designed to meet the needs of different stages: Lab-scale desktop models, 10MW manual models, 100MW automatic models, and GW capacity mass production models.

Shenzhen S.C successfully delivered ink-jet printing equipment, which marks a significant milestone in the Company’s pursuit of a new path for perovskite photovoltaic equipment mass production. The equipment significantly reduces the costs of coating large-area perovskite films, enabling customers to achieve cost reduction and efficiency gains, and accelerating the commercialization of perovskite/crystalline silicon tandem solar cells.

In the future, the Company will continuously improve perovskite photovoltaic equipment manufacturing processes, enhance its stability and production efficiency, and provide the industry with more competitive mass production solutions. The Company looks forward to deepening collaborations with global enterprises and research institutes, jointly driving perovskite photovoltaic technology toward GW capacity mass production, and facilitating the global green energy transformation.
