Organic solar cells more efficient with molecules face-to-face
(Phys.org) —New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor ...
Finding the mix: Solar cell efficiency a delicate balance
(Phys.org) —Research from North Carolina State University reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings ...
Revolutionary solar cells double as lasers
Commercial silicon-based solar cells - such as those seen on the roofs of houses across the country - operate at about 20% efficiency for converting the Sun's rays into electrical energy. It's taken over ...
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.
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 ...
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 ...
Transparent, color solar cells fuse energy, beauty
(Phys.org) —Colorful, see-through solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity.
