Another new technology ......

.... that just might be a major breakthrough. Introducing the LETG (Light Electric & Thermal Generator), which appears to be a combined hybrid PV (Photovoltaic cell) and thermal energy capture (much like Solar Water Heating arrays) device. See Global Warming Solutions.

"The LETG captures and stores sunlight using a hybrid module design that differs from previous combination module devices, making possible the year-round production of thermal and electric energy. Its spectral-selective thermal liquid circulates on the reception surface of a photoelectric circuit, which makes it possible to increase the quantity and to change the quality of incident solar radiation spectral distribution as well as carry out the thermal energy recovery with minimum loss. To put its potential power in perspective, the LETG can increase electric power 250% and thermal output by 170%."

Their press release (via Fox Business News) claims - "Global Warming Solutions, Inc. ....... today announced successful testing of novel, hybrid (heat and electricity generation) solar modules created for the LETG (Light Electric Thermal Generator) project. The combined energy efficiency of the modules reached values of 85%, even exceeding energy harvesting efficiency of green plants."

Considering that most current photovoltaics are considered to be outstanding when achieving anything approaching 20% efficiency, that's one hell of a set of claims. I will await with interest to see what commercialisation of this technology brings.
