Luke Dormehl for DigitalTrends: As the term “regular windows” suggests, users don’t have to replace the existing windows in their home, but need only treat them with a special process developed by the company.
“We apply liquid coatings to glass and plastic surfaces at ambient pressure, and dry these coatings at low temperature to produce transparent films,” Conklin continued. “We repeat these processes, and then collectively these coatings — and thus the glass and plastic surfaces — generate electricity.”
Of these coatings, the most important is the so-called “Active Layer,” through which electricity is generated by the absorption of light, and the transparent conductors, which allow the electricity to be extracted. “[The] coatings are primarily organic, primarily from carbon, hydrogen, nitrogen, and oxygen,” Conklin said. “We are constantly refining each of the layers to improve on the power we’re able to extract from these coatings and enhance their manufacturability.” Cont'd...
Massachusetts Institute of Technology via Science Daily: A team of researchers from MIT and the Masdar Institute of Science and Technology may have found a way around this seemingly intractable tradeoff between efficiency and cost. The team has developed a new solar cell that combines two different layers of sunlight-absorbing material to harvest a broader range of the sun's energy. The researchers call the device a "step cell," because the two layers are arranged in a stepwise fashion, with the lower layer jutting out beneath the upper layer, in order to expose both layers to incoming sunlight. Such layered, or "multijunction," solar cells are typically expensive to manufacture, but the researchers also used a novel, low-cost manufacturing process for their step cell.
The team's step-cell concept can reach theoretical efficiencies above 40 percent and estimated practical efficiencies of 35 percent, prompting the team's principal investigators -- Masdar Institute's Ammar Nayfeh, associate professor of electrical engineering and computer science, and MIT's Eugene Fitzgerald, the Merton C. Flemings-SMA Professor of Materials Science and Engineering -- to plan a startup company to commercialize the promising solar cell. Cont'd...
