Photovoltaics – direct sunlight conversion into electricity using solar cells – has long been lumped with nuclear fusion as one of the great hopes for a boundless, clean energy future, although recent fusion interest has shifted to the more difficult ‘aneutronic’ version, which reduces fusion’s radioactive wastes but is even further in the future. Unlike fusion, the technical viability of photovoltaics has long been established, with this occurring in applications requiring extremes of reliability and durability. Since the early 1960s, photovoltaics has been the main power source for space missions of any duration. Closer to home, it has been the standard power source for telecommunications in remote areas of Australia since the early 1980s. In the same timeframe, there was the view that the photovoltaics industry would grow steadily to a size where it would suddenly take off, as reducing prices opened up new market sectors. Wise heads debated how large a growth rate an emerging industry could sustain over a prolonged period, with a compounded rate of 25 per cent a year a consensus view.
