(Phys.org)—The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new ...
(Phys.org)—At its heart, photovoltaics research is about finding materials with specific properties that make them good at absorbing sunlight and converting it into electricity. The best photovoltaics materials are semiconductors ...
(Phys.org)—Quantum dots are semiconductor crystals that contain a few hundred atoms constrained into such a small space they're considered zero-dimensional objects, often called "artificial atoms." Researchers have fabricated ...
(Phys.org)—Carbon nanotubes (CNTs) are renowned for their thinness, having diameters as small as 3 angstroms (Å), or 0.3 nm. It's generally thought that ultrathin CNTs with diameters smaller than 3 Å are unstable because, ...
(Phys.org) -- Renewable energy technologies generally consist of two distinct processes: energy generation (using sources such as coal, solar, wind, etc.) and energy storage (such as batteries). These two processes are always ...
(Phys.org) -- By connecting a new flexible, thin-film Li-ion battery to a flexible organic LED, a team of researchers from South Korea has demonstrated the first fully functional all-flexible electronic system. In other ...
(Phys.org) -- As their name suggests, Li-air batteries use air to operate, pulling out oxygen molecules to use in a porous, carbon-based cathode, while using lithium in the anode. Because using air means the battery doesn’t ...
(Phys.org) -- In an attempt to lower the cost of making flexible write-once-read-many (WORM) memory devices, a team of researchers from Finland has developed a fabrication process that can mass-print thousands of these memories ...
(Phys.org) -- Since the first demonstration of microelectromechanical systems (MEMS) in the mid-‘80s, the technology has not proven as useful as originally anticipated. One of the problems is that the tiny components ...
(Phys.org) -- One of the biggest challenges facing the silicon photovoltaic industry is making solar cells that are economically viable. To meet this goal, the module cost, which is currently about $1/watt, needs to be decreased ...
