Ultrasolar Technology is a Silicon Valley startup that has developed a pyroelectric device to boost solar cell efficiency.
We all know what “pyro” means, but what is “pyroelectric” all about? According to this Greentech Media piece, which provides a helfpul overview of Ultrasolar’s methodology, “[p]yroelectricity converts heat to [an] electric field.” (more…)

The so-called “artificial leaf,” a solar cell being developed by MIT and Harvard scientists to produce low-cost electricity, is now capable of “self healing” the damage that occurs during energy production, clearing a hurdle to deploying the device in the developing world, scientists say. (more…)

In an interesting case of ancillary legal wrangling, DuPont has filed a declaratory judgment (DJ) action asking an Oregon federal court to declare that the company’s press release and customer letters about its patent infringement suit against Heraeus Precious Metals (Heraeus) does not violate unfair competition laws.
The DuPont DJ complaint describes a dispute arising (more…)

We hear a lot about grid parity, don’t we? That’s the point at which the cost of energy generated by solar, wind, and other renewables is the same as that generated from conventional sources. The author of this article on Sharp Electronics new 43.5%-efficient solar cell writes: “Sharp shattered the efficiency record with its concentrator triple-junction compound solar cell, (more…)

Stanford University researchers say they have developed a “peel-and-stick” solar cell that can be attached to a variety of hard surfaces, an innovation they say could vastly expand the potential for solar energy technology.
Normally, thin-film solar cells are attached to rigid, (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 type of dye-sensitized cell uses an electrolyte made (more…)

Solar3D, a company that develops a three-dimensional solar cell technology to increase conversion efficiency, appeared on News and Fox Business Network last weekend. The article featured an interview with company’s CEO Jim Nelson.
Solar 3D employs the same principle of fiber optic (more…)

As we have written before, Ontario in Canada is working hard to become a hub of alternative energy.
Since 2003, the province has added more than 1,200 MW of installed alternative energy, including 150 solar projects. In 2010 alone, the region added 168 MW of solar power capacity, beating New Jersey (more…)

Solar power works best of course where the sun is brightest. However, another major factor is the capital cost for a solar installation. If your are poor, you cannot get started easily. One of the big opportunities positive climate action has presented the developing world is the chance to leapfrog a generation of energy technology straight into clean, green generation (more…)
