CdS/CdTe Commercial Viability Assessment
When to Use
- Evaluating CdS/CdTe technology for commercial deployment
- Comparing with other photovoltaic technologies
- Assessing market viability and scalability
- Considering environmental and resource constraints
Efficiency Metrics
Laboratory Performance
- Maximum confirmed efficiency: 16.5% (NREL confirmed)
Commercial Performance
- Large area panel efficiency: Approaching 15%
Technology Comparison
| Technology | Efficiency | Notes |
|---|
| Single crystal Si | >20% | Higher efficiency |
| Polycrystalline Si | ~12% | Lower than CdTe |
| CdS/CdTe | 16.5% (lab) | Better stability/fabrication than CIS |
| CIS | ~20% | Higher efficiency but more complex |
Economic Metrics
Production Cost
- Cost: Less than $1/Watt
- Competitive advantage: Low manufacturing cost
Deployment Scale
- Capacity: Multi-gigawatt deployed worldwide
- Status: Commercially mature technology
Material Considerations
Toxicity
- Cadmium (Cd): Highly toxic
- Risk mitigation: Encapsulated cells do not present environmental hazard
- Requirement: Proper encapsulation mandatory
Resource Availability
- Tellurium reserves: Sufficient for explosive industry growth
- Supply constraint: Not a limiting factor
Commercial Advantages vs CIS
CdS/CdTe Advantages
