Abstract :
The mobility of electrons and holes are crucial to the performance of a-Si:H based solar photovoltaic devices. The authors have found that the mobilities of both electrons and holes can be varied over 2 orders of magnitude by control of the ion bombardment energies using the triode type PECVD. The carrier mobilities in the best samples so obtained are an order of magnitude higher than those available hereto, which should considerably enhance the performance of a-Si:H solar cells
