In the Pearl River Delta and Yangtze River Delta regions, the incremental investment can be recovered in approximately 5-6 years.
Taking South China as an example, rooftop installations generate about 130 kWh per square meter per year, facades about 87 kWh, and semi-transparent curtain walls about 43 kWh. If the area ratio of the three positions is 1:1:1, the average annual generation is about 87 kWh per square meter.
Key advantage: East- and west-facing facades generate power during peak-rate hours (8-11 AM and 2-7 PM). At weighted electricity prices, annual savings are approximately 80 CNY/m². The incremental cost of BIPV materials over conventional curtain wall glass is about 400-500 CNY/m², giving a static payback period of about 5-6 years. Projects may also qualify for green building certification credits and floor area ratio incentives in some cities. Overall returns should be evaluated on a project-specific basis.
Our modules have passed a full suite of authoritative certifications, with a design life of 25 years.
Photon Crystal perovskite modules have obtained the following certifications:
Square-meter-scale modules are currently running continuously in multiple outdoor demonstration projects. Warranty terms are available from our sales team along with project proposals.
Perovskite has three core advantages:
| Feature | Perovskite | Crystalline Silicon |
|---|---|---|
| Low-light generation | Continues generating in mornings, evenings, and overcast conditions | Efficiency drops sharply in low light |
| Temperature coefficient | Approx. -0.1%/℃, stable at high temperatures | Approx. -0.35%/℃, significant high-temperature degradation |
| Hot-spot effect | Partial shading does not affect overall generation | Shading causes full-panel failure or even damage |
| Appearance customization | Adjustable color, pattern, and transmittance | Blue/black only, uniform appearance |
Under the same outdoor conditions, perovskite generates 15%-20% more electricity than crystalline silicon, making it better suited for building facades and other complex scenarios.
Yes, it is safe. The product has passed CCC certification and GB/T building safety standards, with complete electrical insulation and fire protection.
Modules use dual-layer laminated tempered glass encapsulation with fully insulated internal circuits and no exposed live parts. Junction boxes are located inside the frame with concealed wiring, rain-proof and dust-proof. The product has passed RoHS EU environmental certification. Installation is performed by certified electricians in compliance with building electrical codes.
Yes.
Per national standard GB 55015-2021, new buildings must meet renewable energy utilization requirements. Perovskite BIPV materials effectively increase the proportion of clean energy in buildings, helping projects meet near-zero energy and zero-carbon building standards and earn green building certification credits. Our technical team can provide dedicated compliance consulting.

Customizable triple-glazed hollow, multi-layer laminated, and multi-layer Low-e composite structures available based on project requirements.
A complete certification portfolio:
Products meet green building certification requirements, helping projects earn green building credits and floor area ratio incentives.
Both are BIPV materials, but perovskite has clear advantages:
| Feature | Perovskite | CdTe |
|---|---|---|
| Module power | 125W/standard panel (continuously improving) | Approx. 100-110W/standard panel |
| Efficiency headroom | Breakthroughs every year | Stagnant at 15%-16% for years |
| Cost | No higher than CdTe | — |
| Environmental impact | No cadmium or heavy metals | Contains cadmium, environmentally restricted |
Not at all. It uses mature building material installation techniques:
Modules use standard frames and mounting hardware. Installation is completed in three steps: framework mounting, glass hoisting, and wiring. Experienced teams can install 100-150 m² per day. On-site technical guidance and installation training are provided.
Photon Crystal is located in Foshan, Guangdong, with batch production capacity for square-meter-scale perovskite modules.
We have established a stable raw material supply chain and partner with multiple logistics providers to ensure project delivery. For large projects, we can arrange stocking plans and staged deliveries.
Perovskite module maintenance is straightforward:
Detailed O&M manuals and training are provided upon project delivery.
The incremental cost of perovskite BIPV materials over traditional materials (e.g., conventional glass curtain walls) is approximately 400-500 CNY/m².
However, considering:
On a full lifecycle cost basis, perovskite BIPV materials have a clear advantage. Dedicated economic analysis reports can be prepared for specific projects.
The technology has entered the industrialization stage, with stability verified.
Photon Crystal uses a proprietary printing and coating process, with a pilot production line established and products delivered in batch. Modules have passed the full IEC aging test suite, and outdoor demonstration projects are running continuously. Leading companies worldwide in the perovskite field have all achieved mass production, confirming the maturity of the technology. Photon Crystal's core team comes from top research institutions with years of accumulated expertise.
Guangdong Photon Crystal Energy Technology Co., Ltd., based in Foshan.
