His presentation was titled: "Silicon Defects and Possible Impact on Solar Cell Efficiency". During his visit to Ankara he also had the opportunity to visit METU - GUNAM - Centre for Solar Research and Applications - an impressive research facility that has the capability of making state of the art solar cells and Kalyon PV - a brand new 1GWp solar panel factory. ISE is starting a joint collaboration with METU - GUNAM and Kalyon - PV to better understand the effect of silicon crystal defects on solar cell efficiency.
