Tell me who you are and where you come from.

My name is Zhang, Zhenhao, coming from Peoples Republic of China.


What was your PhD thesis about?

The title of my PhD thesis was “Nanoscale investigation of potential distribution in operating Cu(In,Ga)Se2 thin-film solar cells”. It was about the investigation of the potential distribution within the layers and at their interfaces of Cu(In,Ga)Se2 thin-film solar cells. The applied method was Kelvin Probe Force Microscopy, which is an advanced technique based on Atomic Force Microscopy. With this method the topography and the electrostatic potential can be measured simultaneously.

What are your future plans?

My plan is still to work in the photovoltaic area of the German industry.

Did KSOP prepare you for your career?

Absolutely! I liked the technical seminars. The most impressive one was on “Laser techniques”. It helps me still in my research topics at work. Moreover, I loved the management seminars. I have participated at almost all of them at that time. They are really helpful for my career in the industry and I check the lecture notes sometimes even now.

What did you like most about KSOP?

Besides the provided seminars I mostly liked the research budget as a part of the scholarship. With that I went to several conferences and symposia, where I quickly acquired the recent research topics of interest. Also, many of my research ideas later on were inspired through face-to-face conversions with other research groups at the conferences.
