U.S. researchers have developed a solar shingle made of flexible glass that could emerge as an alternative to conventional roof shingles and drive down the costs of rooftop solar energy systems. Unlike conventional solar panels, which are bulky


Solar power is a renewable source of energy but still can be expensive to use so any cost reduction is good. Solar engineers from UNSW have developed an innovative method to dramatically improve the quality of low-grade silicon, promising to Read more…


Alphabet Energy (Alphabet) is a Hayward, California, company that develops thermoelectric materials and products that convert waste heat to electric power. Alphabet’s web site provides this overview of the concept of thermoelectrics: Thermoelectrics are solid-state semiconductors that


A team of U.S. scientists says it has developed a class of biodegradable electronics technology that could be utilized for a wide range of products — from consumer devices to medical implants — and that ultimately would dissolve completely, leaving Read more…


The standard solar cell uses silicon oxide, which is expensive and environmentally toxic. One of the promising alternatives is the so-called “Grätzel cell”, a cheaper, cleaner alternative based on more abundant titanium oxide. However, they don’t last long because this Read more…


Evergreen Solar (Evergreen), a Massachusetts silicon PV maker, recently announced that it filed for Chapter 11 bankruptcy and would try to sell its assets under the reorganization. According to the Greentech Media report, those assets include “the String Ribbon technology Read more…


According to a UK solar panel expert, silicon—the primary material in solar panel manufacturing today—may soon be a thing of the past. So what material has the versatility to take its place? You guessed it: plastic. While there is a variety of reasons plastic trumps silicone, it comes down to three main points: flexibility, weight […]


During Solar Power International 2010 (SPI 10), each afternoon there were more than eight concurrent conference sessions. It was not possible to attend them all, but the “The Next Great Solar Cell Material: What Technology Will Emerge Dominant on the Read more…


Stanford engineers are finding that the conventional limits on solar cell efficiency may not apply at subwavelength light levels and under certain material conditions.


U.S. investors have invested $129.4 million in a promising solar technology that uses plastic lenses to concentrate sunlight onto small but highly efficient solar cells. The so-called multijunction cells, developed by California-based Amonix, generate more electricity than conventional photovoltaic panels Read more…


Shrink Nanotechnologies is one of several companies that is using bioplastics to find a new way of making devices that will minimize the use of increasingly-scarce rare metals. The company’s OptiSol Solar Concentrator is billed as a nanotechnology-based plastic solar Read more…
