Perovskite solar cells become even more promising with cheaper materials
Solar cells made from polar nanocrystal inks show promising early performance
Nanostructures enhance light trapping for solar fuel generation
World's smallest reference material is big plus for nanotechnology
If it's true that good things come in small packages, then the National Institute of Standards and Technology (NIST) can now make anyone working with nanoparticles very happy. NIST recently issued Reference ...
New connection between stacked solar cells can handle energy of 70,000 suns
(Phys.org) —North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar ...
New breed of solar cells: Quantum-dot photovoltaics set new record for efficiency in such devices
Solar-cell technology has advanced rapidly, as hundreds of groups around the world pursue more than two dozen approaches using different materials, technologies, and approaches to improve efficiency and reduce ...
Tiny 'Lego brick'-style studs make solar panels a quarter more efficient
(Phys.org) —Rows of aluminum studs help solar panels extract more energy from sunlight than those with flat surfaces.
New paradigm for solar cell construction demonstrated
(Phys.org) —For solar panels, wringing every drop of energy from as many photons as possible is imperative. This goal has sent chemistry, materials science and electronic engineering researchers on a quest ...
Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
New device stores electricity on silicon chips
(Phys.org) —Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges.
Environmentally friendly solar cell pushes forward the 'next big thing in photovoltaics'
Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly ...
'Photon glue' enables a new quantum mechanical state
(Phys.org) —Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials.
Yale engineer to build 'hot' solar cells
Associate professor of electrical engineering Minjoo Larry Lee has been awarded $2,540,000 to develop dual-junction solar cells that can operate efficiently at extreme temperatures above 750 degrees Fahrenheit. ...
New class of nanoparticle brings cheaper, lighter solar cells outdoors
Think those flat, glassy solar panels on your neighbour's roof are the pinnacle of solar technology? Think again.
