Recent improvements in solar power technology have been divided into two camps, photovoltaic and solar concentrators. Large arrays of both kinds in increasing numbers have been financed recently.

A new technique developed at MIT promises to offer some of the best of both worlds, a series of glass panels that utilizes organic dyes to make different wavelengths of light turn sideways and go to the edges of the glass where small photovoltaic cells turn those light waves into electricity. This makes the main part of the collectors nothing more than tinted glass that can be incorporated into roof-top solar panels or even used as windows. It requires no mirrors or tracking devices which require maintenance and break down over time. Though no time line for production of these is given, a de-centralized, non-mechanical PV system seems to offer a lot of promise.
