Product Specification

Custom Tansmittance CdTe Solar Glass BIPV Facade Power Glass for Building Exterior

CdTe (Cadmium Telluride) power glass refers to a type of photovoltaic (PV) technology that integrates thin-film CdTe solar cells into glass panels, enabling them to generate electricity while maintaining transparency or semi-transparency. This technology is primarily used in building-integrated photovoltaics (BIPV), such as windows, facades, and skylights, combining energy generation with architectural design.

​​Key Features of CdTe Power Glass:​​

1. ​​High Efficiency​​ – CdTe thin-film solar cells have achieved efficiencies exceeding ​​22%​​ in lab conditions (commercially ~18-19%), making them competitive with traditional silicon-based PV.

2. ​​Semi-Transparency​​ – Can be tuned to allow partial light transmission (useful for windows).

3. ​​Low-Light Performance​​ – Performs better than silicon in diffuse or low-light conditions.

4. ​​Cost-Effective​​ – CdTe is cheaper to manufacture than crystalline silicon due to lower material and processing costs.

5. ​​Aesthetic Flexibility​​ – Can be customized in color and transparency for architectural applications.

6. ​​Durability​​ – CdTe modules are robust and perform well in high-temperature environments.

​​Applications:​​

• ​​Solar Windows​​ – Semi-transparent power-generating glass for buildings.

• ​​Building Facades​​ – Energy-producing curtain walls.

• ​​Skylights & Canopies​​ – Generating electricity while providing shade.

• ​​Greenhouses​​ – Balancing light transmission and energy production.

​​Challenges:​​

• ​​Cadmium Toxicity​​ – CdTe contains cadmium, requiring proper recycling (though manufacturers like First Solar have established take-back programs).

• ​​Lower Efficiency Than Silicon in Standard Conditions​​ – Though better in real-world low-light/high-temp scenarios.

• ​​Market Competition​​ – Faces competition from perovskite and traditional silicon BIPV solutions.

​​Leading Companies:​​

• ​​First Solar​​ (largest CdTe solar panel manufacturer, though mostly for utility-scale, not yet BIPV-focused).

• ​​Other BIPV-focused startups​​ are exploring CdTe glass integration.

​​Future Outlook:​​

CdTe power glass is a promising solution for energy-generating buildings, especially as urbanization and green building standards rise. Advances in tandem cells (e.g., CdTe + perovskite) could further boost efficiency and adoption.
