From the roof to the facade

Applications of Conventional Building Envelopes

Cadmium telluride modules are reshaping the appearance and functionality of buildings, transforming conventional building envelopes into high‑efficiency green energy generators. On building rooftops, Cadmium telluride photovoltaic tiles can directly replace conventional roofing tiles and, thanks to their high degree of customization, seamlessly integrate with a wide range of architectural styles. Compared with conventional photovoltaic panels, cadmium telluride modules exhibit superior resistance to shading. It is particularly well-suited to the complex structures of rooftops and localized shading conditions. , effectively preventing power generation losses and system failures caused by shading. In addition, cadmium telluride modules support personalized customization, including color options and corporate logos, Break the monotonous, uniform layout of conventional rooftop photovoltaic arrays, Truly achieving seamless integration with the building’s roof.  

On the rooftop of XPeng’s new global headquarters, Yicai modules are arranged to form an “X” shape, while cadmium telluride (CdTe) modules on the building’s façade represent an even more revolutionary approach. These modules can serve as curtain‑wall glass, skylights, or residential sunrooms, seamlessly integrating daylighting, power generation, and aesthetic design. By precisely tuning their light transmittance, they not only meet indoor natural lighting needs but also generate substantial electricity, truly embodying the vision of “turning every inch of a building’s envelope into green value.” Such BIPV applications significantly enhance building energy efficiency, and their cutting‑edge, custom‑designed aesthetics give structures a distinctive green identity, making them a shining hallmark of low‑carbon urban development.

Empowering Modern Agriculture

Green Production Driven by Multiple Benefits

The application of cadmium telluride modules in the agricultural sector has ushered in a new chapter for “photovoltaic agriculture.” At its core lies the unique property of generating electricity while allowing light to pass through. Cadmium telluride transparent photovoltaic glass can be tailored to meet the varying light‑requirement needs of different crops, Customizable adjustment of light transmittance While ensuring that crops can carry out sufficient photosynthesis, it can also harness abundant sunlight to generate electricity.

This new type of agricultural greenhouse achieves “multi‑use on a single plot” and “energy self‑sufficiency.” Without altering the land’s designated use, it enhances land‑use efficiency. The electricity generated by the photovoltaic modules can also meet the power needs of irrigation, supplemental lighting, and temperature‑control systems within the greenhouse, with any surplus fed back into the grid for sale. , bringing farmers a stable source of additional income. In addition to its two core functions—generating clean electricity and ensuring optimal photosynthesis for crops—the cadmium telluride photovoltaic modules also create a localized microclimate that benefits the plants, Resist the impact of extreme weather conditions such as hail and strong winds. In arid regions, it can still… Effectively reduces the rate of water evaporation from the soil, Enabling crops to grow naturally even when irrigation needs decrease.

Reimagining the Transportation Network

The Green Artery of the Intelligent Transportation System

In the transportation sector, cadmium telluride modules are quietly transforming the way energy is generated and utilized. First, in more conventional “integrated solar‑storage‑charging” parking lots and charging stations, Cadmium telluride BIPV carports integrate parking spaces with power-generation facilities, The green electricity generated is prioritized for the on-site charging stations, creating a closed-loop system in which new-energy vehicles are powered by new-energy electricity.

Secondly, a more innovative scenario is Automotive skylight glass . Cadmium telluride skylight glass transforms the car roof into an “invisible generator,” Provides power to in-vehicle auxiliary systems such as the air conditioner and mini refrigerator. , thereby reducing the load on the power battery. It can also take advantage of its ability to selectively filter infrared radiation, Reduce heat gain from solar radiation, achieving a dual improvement in energy efficiency and user experience. This transforms the automobile from a mere “energy consumer” into a “mobile energy node,” aligning with the automotive industry’s decarbonization trajectory across the entire lifecycle.

Finally, it is about making full use of road space. Photovoltaic Sound Barrier . Integrating cadmium telluride bifacial photovoltaic glass into noise barriers along highways and elevated roadways enables these structures to serve both as noise‑reducing, environmentally friendly features and as rows of “vertical power stations.” Measured data show that, After a photovoltaic sound barrier was installed on an elevated roadway in Hangzhou, the sound insulation improved by 5 to 6 decibels. Photovoltaic sound barriers transform the one-time capital expenditure of conventional environmental‑management infrastructure into a power‑generating asset that continuously produces clean electricity, offering a fresh approach to the green upgrading of linear infrastructure and unlocking substantial market potential.

Illuminating the Marginal Space

Ubiquitous Green Potential

In addition to the aforementioned key sectors, cadmium telluride modules are increasingly making inroads into various “marginal spaces” within urban areas, unlocking the power-generation potential of fragmented zones. In the realm of photovoltaic landscapes, cadmium telluride PV modules can be seamlessly integrated into… Public art installations such as pavilions and pergolas ， It can also be integrated into pedestrian pathways in the form of photovoltaic paving tiles. Its high strength withstands everyday pedestrian traffic, while the surface is treated with an anti-slip finish to prevent slipping. It integrates seamlessly into the pavement, harvesting energy almost imperceptibly.

Whether at the perimeter of an industrial park or along the exterior fencing of a building, it can generate electricity within limited spaces, enhancing spatial functionality and delivering additional revenue.

Among various types of shading facilities ， Such as bus shelter canopies, corridors, and shading louvers on building facades, etc. Cadmium telluride modules provide comfortable shade, regulate the thermal and lighting environment, and continuously convert sunlight into electricity. Such installations are often located in high‑traffic areas, not only delivering multiple functions in a single solution but also conveying a green, technology‑driven urban image to the public.

From the façade of buildings to the roofs of agricultural structures, from the arteries of transportation networks to the hidden corners of cities, cadmium telluride modules, with their outstanding technical attributes and robust integration capabilities, are continually pushing the boundaries of photovoltaic applications. They are more than mere power-generating devices; they serve as multifunctional platforms that bridge energy, the environment, the economy, and social development.
