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.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
