Editor's Notes
- #2 There are three processes throughout the entire investigation for each quantum dot solar cell project. We growth the materials on the substrate wafer. The device structure is the commonly used p-i-n junction, including quantum dots. We can grow different types of quantum dots based on our study. We develop them into workable devices using basic photolithography procedures. We characterise the devices using the available apparatus that we have. They include photoluminesnce, atomic force microscopy, light JV measurements and external quantum efficiency.
