Design and Fabrication of CNT-Silicon Solar Cells

Incorporating carbon nanotubes (CNTs), graphene or performing polymers with classic silicon wafers causes guaranteeing solar cell architectures with quickly improved power alteration efficiency until just lately. Here, we survey CNT-Si junction solar panels with efficiencies attaining 15% by finish a TiO2 antireflection covering and doping CNTs with oxidative chemicals, under air mass (AM 1.5) brightness at a calibrated power of 100 mW/cm2 and a dynamic device section of 15 mm2. The TiO2 covering significantly inhibits light reflectance from the Si surface, leading to much increased short-circuit current (by 30%) and exterior quantum efficiency. Our method is easy, well-controlled, and incredibly effective in increasing the performance of CNT-Si solar panels.
