Putting solar cells on plastic creates some interesting possibilities, according to University of California chemists A. Paul Alivisatos, Wendy Huynh, and Janke Dittmer. "This opens up all sorts of new applications, like putting solar cells on clothing to power LEDs, radios, or small computer processors," says Dittmer. The team created a hybrid solar cell made from tiny rods dispersed in an organic polymer layer. The nanorods act like wires. When they absorb light, they generate electrons, which travel the length of the rod until collected by an aluminum electrode. The polymer layer is 200 nanometers thick—less than the width of a human hair—and is sandwiched in between the electrodes. The hybrid solar cell generates 0.7V. Unlike semiconductor-based photovoltaic devices, the plastic solar cells can be made without clean rooms and vacuum chambers. Visit www.berkeley.edu.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
