Secrets Of New Solar Material Unlocked
2014-04-22 15:44:42

National Renewable Energy Laboratory A new solar material that has the same crystal structure as a mineral first found in the Ural Mountains in 1839 is shooting up the efficiency charts faster than almost anything researchers have seen before—and it is generating optimism that a less expensive way of using sunlight to generate electricity may be in our planet's future. Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) are analyzing the new material,...

Photovoltaic energy conversion offers one of the best means for the future of renewable energy in the world. The efficiency of solar cells depends heavily upon the light-absorbing materials they use. Photovoltaic systems based on lead halide perovskite are a new, revolutionary type of device with efficiencies currently exceeding 16%. However, a detailed description of how these solar cells turn light into electrical current is still lacking. Publishing in Nature Photonics, scientists from...

Is 3D Graphene Solar Power's Next Platinum?

Michigan Technological University One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them. Dye-sensitized solar cells are thin, flexible, easy to make and very good at turning sunshine into electricity. However, a key ingredient is one of the most expensive metals on the planet: platinum. While only small amounts are needed, at $1,500 an ounce, the cost of the silvery metal is still significant....

Organic solar cells, a new class of solar cell that mimics the natural process of plant photosynthesis, could revolutionize renewable energy - but currently lack the efficiency to compete with the more costly commercial silicon cells. Currently, organic solar cells can achieve as much as 12 per cent efficiency in turning light into electricity, compared with 20 to 25 per cent for silicon-based cells. Now, researchers have discovered that manipulating the 'spin' of electrons in these...

The Solar Cell That Also Shines: Luminescent 'LED-type' Design Breaks Efficiency Record
2012-04-19 11:25:59

Research to be presented at the Conference on Lasers and Electro Optics illuminates 50-year mystery To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested — and demonstrated — a counterintuitive concept: solar cells should be designed to be more like LEDs, able to emit light as well as absorb it. The Berkeley team will present its findings at...

Rice, Tsinghua collaboration could yield low-cost, efficient alternative to silicon-based cells Forests of carbon nanotubes are an efficient alternative for platinum electrodes in dye-sensitized solar cells (DSC), according to new research by collaborators at Rice University and Tsinghua University. The single-wall nanotube arrays, grown in a process invented at Rice, are both much more electroactive and potentially cheaper than platinum, a common catalyst in DSCs, said Jun Lou, a...

Scientists from the University of Picardie Jules Verne and the Swiss Federal Institute of Technology are reporting development of a new genre of an electrolyte system for solar cells that breaks the double-digit barrier in the efficiency with which the devices convert sunlight into electricity. Their study appears in Journal of the American Chemical Society. Frederic Sauvage, Michael Graetzel and colleagues describe research that aimed to develop an improved version of a highly promising...

The sun provides more than enough energy for all our needs, if only we could harness it cheaply and efficiently. Solar energy could provide a clean alternative to fossil fuels, but the high cost of solar cells has been a major barrier to their widespread use. Stanford researchers have found that adding a single layer of organic molecules to a solar cell can increase its efficiency three-fold and could lead to cheaper, more efficient solar panels. Their results were published online in ACS...

Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
