IBM's Efficient Thin Film Solar Cell Made of Cheap Materials
They managed to increase the efficiency with almost 40% of their solar cells, from 6,7 percent to 9,6 percent. To reduce even more the costs, these solar cells are build with an inexpensive ink-based process.
New Flexible Silicon Solar Cells Use 99 % Less Material With Same Efficiency
CalTech researchers discovered a new way to make silicon solar cells that not only use 1 percent of the material needed to make conventional cells, but which are also thin and flexible, making them suitable for a much larger palette of uses in all kinds of applications. And let's not mention the fact that the price will be considerably lower, respectively.
Semprius's Micrometric Solar Cells Efficient in Concentrated Photovoltaic Systems
Concentrated photovoltaic systems are usually more effective than regular, flat ones, because a lens focuses the sunlight on a smaller surface of some efficient and more expensive solar cells 500 times stronger than the cells would receive in regular operation. Heat is mostly a problem with concentrated PV systems, since it has to be efficiently dissipated through complex and expensive cooling technique.
World's Smallest Solar Powered Sensor Invented by University of Michigan Researchers
University of Michigan engineers developed the smallest solar powered sensor system, having only 9 cubic millimeters, that can harvest energy from ambient light to operate.
Self-Powered Solar Circuit Could Help Computing Become Greener and Faster
A team of scientists at the University of Pennsylvania have developed the world's first circuit powered by solar energy that can power itself, as long as it's left in a beam of sunshine. It could eventually power a new line of consumer devices or even model the human brain.
Astounding Discovery: Marine Algae Using Quantum Mechanics Principles for Light Harvesting
Professor Greg Scholes, the lead author of the study published recently in Nature, says: "There's been a lot of excitement and speculation that nature may be using quantum mechanical practices. Our latest experiments show that normally functioning biological systems have the capacity to use quantum mechanics in order to optimize a process as essential to their survival as photosynthesis."
Sixtron's Antireflective Coatings Solve Safety and Efficiency Issues in Solar Cell Technology
Up to now, the most used antireflective coating method has been the vapor deposition of a silicon nitride film by using a highly-flamable silane gas, which can ignite when exposed to air. Transporting, storing, ventilating silane gas and other safety-keeping operation make the process very expensive.
USAF Solar Project to Generate up to 500MW of Green Electricity
The partnership that took place a few days ago between United States Air Force and Fotowatio Renewable Ventures of San Francisco could lead to the construction of United State's largest solar project that will be able to produce 500MW of green electricity.
Scientists Hack Tobacco Plants to Grow Synthetic Photovoltaic Cells
A group of scientists at the University of California, Berkeley, have developed a way to produce artificial photovoltaic and photochemical cells by infecting the tobacco plants with a genetically engineered virus. Unlike traditional methods of making solar cells, this new technique is more environmentally friendly (because the cells are biodegradable) and cheap.
Weidlinger's Hybrid Roof Solar Panels Delivering Both Electricity and Heat
Usually, heat and light cannot be separated, because heat is a also a form of energy that we can't ignore. Weidlinger Associates, a NY-based company, received a $150,000 grant this week to develop better, more durable hybrid solar roof panels.
