Solar Cell Bypass and String Blocking Diode Development

Project: Research project

Description

Arizona State University is a world leader in single-crystal diamond research. Consequently, working with ASU means Advent Diamond will have access to some of the best diamond reactors as well as access to an extensive knowledge base in the field. Moreover, the ASU group has substantial experience fabricating diamond devices and they have developed a custom simulation program (Silvaco) to guide the materials optimization for the high power diodes for this program. The ASU team has extensive research on diamond radiation detectors based on pin diodes which will be directly applicable to this project.

The ASU team will fabricate state of the art diode structures with specifications for radiation resistant, high temperature and high-power operation. The ASU diamond growth facility has separate systems for ultra-pure intrinsic diamond deposition and n-type diamond deposition. These systems will enable fabrication of radiation resistant, high voltage diodes that operate at high temperature. The ASU team will provide SIMS characterization to confirm the doping concentration, impurity content and thickness of the epitaxial layers. The ASU team will simulate the electrical characteristics of the devices before and after radiation exposure and predict the characteristics for longer-term exposure. In addition, they will provide expertise related to this technology.
