The efficiency with which photons are absorbed and converted to electric current depends on the size, orientation, volume fraction, and interface properties of nc-Si. This investigation has resulted in the development of a device level simulator which predicts quantum efficiency and voltage-current character for nc-Si/a-Si systems. These performance measures are calculated as functions of input photon energy. A number of different interactions were combined to completely characterize the device, including optical scattering and absorption, creation of excitons and charge carriers, electrostatic fields, and drift/diffusion of charge carriers.postersengCopyright of the original work is retained by the author.REMRSECText
