Abstract
This Small Business Technology Transfer (STTR) Phase I project will demonstrate a new method of thermographic imaging to improve the manufacturing yield and energy conversion efficiency of silicon photovoltaic solar cells. Although thermographic imaging is an ideal method for locating the defects and shunts in solar cells which compromise their efficiency, conventional infrared cameras do not have sufficient spatial resolution to be effective as a production tool for NDE (Non-Destructive Evaluation). The proposed technology will produce 100X higher spatial resolution with 1 mK thermal resolution at much lower system cost than infrared cameras.
