Image force effects on carrier collection in a -Si:H solar cells
A modified carrier collection model of a-Si:H Schottky-barrier solar cells is proposed to explain the falloff of short wavelength carrier collection efficiency. Schottky-barrier lowering due to image force effects alters the potential distribution near the metal-semiconductor interface. This altered...

| Summary: | A modified carrier collection model of a-Si:H Schottky-barrier solar cells is proposed to explain the falloff of short wavelength carrier collection efficiency. Schottky-barrier lowering due to image force effects alters the potential distribution near the metal-semiconductor interface. This altered potential decreases the carrier collection in a-Si:H solar cells by as much as 30%. Design considerations to improve carrier collection efficiency are also proposed. |
