Technology and innovation: Rule number one: Never bet against silicon

I have been wondering for quite some time why so many good researchers in Australia are working on organic solar cell technologies. I am sure they have their reasons, but, for those of us on the inside of the photovoltaics industry (I am, among other things, CEO of BT Imaging, Australia's sole exporter of manufacturing tools for photovoltaic manufacturing), these efforts leave us scratching our collective heads.
