Ideal Structure for Organic/Nanomaterial Solar Cells

Organic/nanomaterial hybrid solar cells

Maximizes conversion efficiency Reduces interface charge recombination Eliminates the possibility of electrical shorting Provides greater charge mobility Improves photon absorption

Berkeley Lab researchers have developed a structured configuration for organic/nanomaterial hybrid solar cells that maximizes conversion efficiency by increasing the chance that excitons will reach an interface before recombining. The new geometry will vastly reduce the possibility of electrical shorting and minimize the interface electronics problems encountered when irregular blend morphologies are employed. A variety of electron donor polymer and electron acceptor nanocomposite materials can be used in this invention and both the donor and acceptor materials can be optically absorbing for higher efficiency.
