High-Concentration Photovoltaic Thermal System From IBM Promises 80% Efficiency, Potable Water, And Air Conditioning

April 24, 2013 Nathan

This article was originally published on Solar Love.

How does a cost-competitive photovoltaic system that is able to concentrate sunlight 2000 times and then capture 80% of the concentrated energy sound? Pretty good, right? Such a system is currently being developed by researchers at IBM Research, Airlight Energy, ETH Zurich, and Interstate University of Applied Sciences Buchs NTB, after winning a three-year $2.4 million grant from the Swiss Commission for Technology and Innovation.

And in addition to generating electricity, the system can itself desalinate water and provide air-conditioning, useful features for the sunny and remote regions that the system is designed for.

An economical High Concentration Photovoltaic Thermal (HCPVT) system, that in addition to supplying electricity can desalinate water and provide air conditioning, is the complete package as far as many regions of the world are concerned.


The prototype system makes use of a large parabolic dish, composed of a number of mirror facets, which are coordinated to a sun tracking system. The system automatically repositions itself to the optimum angle for power generation. The sunlight that hits the mirrors is reflected off of them onto a number of microchannel-liquid cooled receivers with triple junction photovoltaic chips. Every one of these 1×1 centimeter chips “can convert 200-250 watts, on average, over a typical eight hour day in a sunny region.” And there are hundreds of these chips in the design, providing a total of about 25 kilowatts of electrical power.

As noted in the video below, we only need about 0.4% of the solar energy arriving on the Earth to supply ALL of our ENERGY NEEDS!

We DON'T NEED FOSSIL FUELS! We DO NEED to stop using them. The claim 😈 that we MUST rely on fossil fuels 🦖 for now because they are "cheap" is inaccurate, erroneous and outdated information.  Watch this video for PROOF!
