A-Si:H Followed by a Micro-crystalline Si Layer

The micro-crystalline Si layer has also a smaller band gap than a-Si:H and increases the conversion efficiency substantially. These new layers are also referred to as nano­crystalline layers and are produced similarly to the a-Si:H layer in a high frequency ac-gas discharge at 13.56 MHz, however using a larger current density.
