As a Chemical Engineer, I have always had a kindred feeling for solar thermal because, other than the computer-controlled mirrors, the rest of the technology is well established engineering, i.e., high pressure boilers, heat exchangers, steam turbines, electric generators, etc.
However, I also believe in the simple approach to solving a problem, and what can be more simple than having sunlight impinge on a silicon wafer and come out as electricity?
So who is winning? Well the linked news story from The Street indicates the simple approach just took a quantum leap ahead. You be the judge. I am guessing it will still take a lot more time to really sort this out, and maybe both approaches will have a place in our future.
