研究目的
Investigating the effects of n-type Molybdenum Telluride (n-MoTe2) in the back contact interface between the Cadmium Telluride (CdTe) absorber layer and Mo layer on the performance of CdTe solar cells.
研究成果
The numerical analysis revealed that the performance of CdTe solar cells is significantly affected by the presence of n-MoTe2 in the back contact interface. Optimal performance was observed at a layer thickness of 60 nm, operating temperature of 350 K, donor concentration of 1×1016 cm-3, and sun intensity of 1.1 suns, achieving an efficiency of 16.532%. This study provides valuable insights into the design and optimization of CdTe solar cells with n-MoTe2 back contacts.
研究不足
The study is based on numerical simulation, which may not fully capture all real-world conditions and material behaviors. The practical fabrication of solar cells with the optimal parameters identified may present challenges.
