The language projecting the cost savings for this new solar technology is somewhat dubious as usual. Even if the developers of this technology have good reason to think that the cadmium sulfide based solar panel technology will cost 1/10th compared to today's cost of developing silicon based solar panels, what happens between now and when they are able to take this technology to mass production in five or more years?
There is a massive world-wide technology complex driving the optimization of silicon based manufacturing technology. The amount of capital invested into silicon manufacturing process and tools is measured in tens of billions of dollars per year, if not hundreds of billions. If the conventional process improvements is able to achieve 20-25% cost improvement per year, in five years, the cost of panels based on conventional panels would be down to 25-30% of today's cost. A few hickups in the development of the new technology like yield or reliability issues can easily delay the mass deployment by a few years which will negate all cost benefits. Not to mention the possibility of cadmium prices going up if the volumes are picking up...
And don't forget the cost of capital investment, which is already funded due to other "useful" applications in the silicon case. Most other technologies that tried to compete against silicon lost so far, not because of fundamental technical issues but because of the economics involved.
I am not against developing new innovative technologies to achieve substantial improvements in the solar power area. However, it is best to keep the optimism about new and unproven technologies in control until they reach at least beta production stage...
