Tiny step edges, big step for surface science
An interesting effect could help build better solar cells and create better chemical catalysts: If a titanium oxide surface is completely flat, the electrons inside the material can move freely. But if there ...
Scientists discover material that can be solar cell by day, light panel by night
In the future, when your mobile or tablet runs out of battery, you could just recharge it by putting it out in the sun. Nanyang Technological University (NTU) scientists have developed a next-generation solar ...
Photon funnel could direct and regulate light into solar cells
Engineering team designs 'living materials'
Inspired by natural materials such as bone—a matrix of minerals and other substances, including living cells—MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving ...
Meta-transmitarray offers unprecedented control of light on subwavelength scales
Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
Tiny crystals to boost solar
A new approach to studying solar panel absorber materials has been developed by researchers in France, Acta Cryst. (2014). B70, 390. The technique could accelerate the development of non-toxic and readil ...
New findings to help extend high efficiency solar cells' lifetime
OIST's Energy Materials and Surface Sciences Unit has made a surprising discovery about the degradation of solar cells that could help pave the way to creating a longer lifetime for these cells. Key factors ...
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 ...
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 ...
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.
'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.
