英文摘要	Hong Kong Research Grant Council [HKU7009/09P, 7009/12P, 7007/11P, HKUST9/CRF/11G]; University Grant Council [AoE/P-04/08]; National Natural Science Foundation of China [NSFC 21322306, NSFC 21273186]; National Basic Research Program of China [2014CB921402]; Previous simulations of photovoltaic devices are based on classical models, which neglect the atomistic details and quantum-mechanical effects besides the dependence on many empirical parameters. Here, within the nonequilibrium Green's function formalism, we present a quantum-mechanical study of the performance of inorganic nanowire-based photovoltaic devices. On the basis of density-functional tight-binding theory, the method allows simulation of current-voltage characteristics and optical properties of photovoltaic devices without relying on empirical parameters. Numerical studies of silicon nanowire-based devices of realistic sizes with 10 000 atoms are performed, and the results indicate that atomistic details and nonequilibrium conditions have a clear impact on the photoresponse of the devices.
