The Fellowship would be used to launch a major new initiative addressing one of the key challenges facing microelectronics, the incorporation of optical functions into high density silicon integrated circuits, as well as accelerating development of a "third" generation of photovoltaic solar cells using similar techniques. This third generation thin-film technology would be capable of fundamentally higher energy conversion efficiency than earlier generations, at low cost. In both cases, the targeted outcome over the period of the Fellowship is to develop technology to the stage where it can be commercially evaluated, in a way likely to maximise Australian benefits.
