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...

Nanotubes Solar Cells Heat And Light

[ Watch the Video: Tapping The Sun's Energy In New Ways ] Brett Smith for redOrbit.com - Your Universe Online Like a beautiful piece of music being played on an out-of-tune instrument, conventional photovoltaic material (PV) used to capture solar energy is slightly out of tune with natural sunlight. A new system being developed by researchers at MIT looks to correct this dissonance by using sunlight to heat a high-temperature material that then radiates an optimal wavelength of...

New Light Shed On Mystery Mechanism That Allows Positive And Negative Charges To Be Separated Efficiently

University of Cambridge By using an ultrafast camera, scientists say they have observed the very first instants following the absorption of light into artificial yet organic nanostructures and found that charges not only formed rapidly but also separated very quickly over long distances - phenomena that occur due to the wavelike nature of electrons which are governed by fundamental laws of quantum mechanics. This result surprised scientists as such phenomena were believed to be limited...

New Material For Solar Panels Could Make Them Cheaper And More Efficient
2013-12-12 08:01:27

Argonne National Laboratory A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time. It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light. Scaling up this new design from its tablet-size prototype to a full-size solar panel would be a large step...

Solar Cell Degradation Seen Directly For The First Time
2013-12-09 16:02:32

DESY X-ray Examination Shows Structural Changes In "Plastics" Solar Cells With the help of DESY’s X-ray light source PETRA III, researchers of Technische Universität München have, for the first time, watched organic solar cells degrade in real time. This work could open new approaches to increasing the stability of this highly promising type of solar cell. The team headed by Prof. Peter Müller-Buschbaum from the Technische Universität München (Technical University of Munich)...

Study Could Lead To Paradigm Shift In Organic Solar Cell Research
2013-11-20 09:56:25

Stanford University Organic solar cells have long been touted as lightweight, low-cost alternatives to rigid solar panels made of silicon. Dramatic improvements in the efficiency of organic photovoltaics have been made in recent years, yet the fundamental question of how these devices convert sunlight into electricity is still hotly debated. Now a Stanford University research team is weighing in on the controversy. Their findings, published in the Nov. 17 issue of the journal Nature...
