Research Spotlight: Organic Solar Using Sputter and Thermal Processes

A research spotlight on flexible and transparent organic photovoltaic devices made with sputter and thermal deposition.
This research spotlight, originally dated August 17, 2016, follows work by Yuelin Peng in Professor Trisha Andrew’s group at the University of Wisconsin–Madison on flexible and transparent organic photovoltaic devices.
The device workflow combines sputter deposition for metal-oxide insulation and bottom-electrode-related layers with thermal evaporation for organic semiconductor layers and the top electrode. A dual-chamber Angstrom Engineering PVD system keeps the two process families connected while giving each a suitable deposition environment.
An organic solar device may require more than ten sequential layers. Good uniformity, repeatable thickness control and the ability to program an entire sequence become increasingly important as the layer count rises; automation lets a researcher establish the process and allow the system to execute it consistently.
The system can control film thickness at very fine resolution while preserving repeatability across the active area. For device studies, this reduces uncertainty from the deposition platform and makes it easier to attribute performance changes to material or interface design.
Peng also highlighted the value of technical support when learning the system as a new laboratory user. Responsive help with operation and process setup can shorten the path from equipment training to repeatable device fabrication.
