Controlling the Structure of Organic/Nanomaterial Solar Cells
APPLICATION OF TECHNOLOGY:
Organic/nanomaterial hybrid solar cells
Introduces a new parameter for controlling solar cell morphology Improves conversion efficiency by increasing mobility and photon absorption and reducing electron/hole recombination
In order to attain an improved blend solar cell design, Berkeley Lab researchers have invented an elegant technique for controlling and tuning morphology beyond the current methods of “shaking and baking.” Using this new method, the orientation and growth alignment of the electron-conducting material can be guided during synthesis, enabling the creation of narrow electron conducting channels. This design feature leads to reduced electron/hole recombination, more efficient photon absorption, greater charge mobility, and improved interfacial electronic structure.
