1. Technical Challenges
A: Conversion efficiency bottleneck: The laboratory record is 22.1%, but the efficiency of mass-produced modules is generally 16-19%, which is lower than 23%+ of crystalline silicon.
B: Low material safety
C: Indium scarcity
D: Stability issues: Long-term outdoor operation may cause back contact degradation (copper diffusion), and the buffer layer needs to be optimized
2. Application scenarios
A: Large ground power stations (accounting for more than 80%), especially suitable for high-irradiation arid areas
B: Building-in-Platform Photovoltaic (BIPV): transparent or colored modules are used for curtain walls and roofs.
C: Lightweight flexible modules
3. Future development direction
A: Gradient bandgap design broadens spectral absorption
B: Perovskite/CdTe stacked cells
C: Cadmium-free exploration: research on alternative materials.
D: Flexible technology: low-temperature deposition on polymer substrates to expand the wearable and mobile energy markets.
CdTe thin-film modules are irreplaceable in specific markets due to their cost and weak light advantages. Despite the controversy over efficiency and materials, technological progress and circular economy models are expected to promote its continued development, especially in distributed energy and emerging markets.
