Cyrium Technologies said today that Harry Rozakis, a veteran of the chip industry, will become the new CEO.

The Canadian company has touted solar cells that can convert 40 percent or more of the light that strikes them into electricity. The cells aren't made of silicon, which some experts say maxes out at 29 percent efficiency. Instead, it makes quantum dot triple junction solar cells. These cells could then be placed under a a concentrator to crank out power. But it's exotic science so naturally you don't see stacks of them next to the barbecues at Home Depot yet. The technology largely emerged from the Simon Fafard. Steve Eglash, a venture capitalists, took over as CEO in December 2007. It then raised $15 million in a Series B round in July. No word on where Steve went.

The secretive Quercus Trust is one of the investors.

Concentrators, like thin film solar companies, are in a limbo state these days. A few years ago, silicon prices were soaring and demand for raw sillicon and solar panels raged. Now, demand has dropped, solar panel manufacturers have managed to squeeze more costs out of their operations and everyone wonders how alternatives to traditional glass 'n' sand solar panels will really fare. We shall see.
