<p>Hi everyone,</p>
<p>I would like to ask you which way one should follow when searching for a phd program. I am thinking of studying on photovoltaics but i am having great difficulty in determining which universities to apply to. Because when i search on the websites of universities, all of them seem to be doing something on photovoltaics but i can't get an idea of how advanced their studies are. Some friends of mine suggested me to search for professors instead of universities. I tried the way of examining the reference sections of papers to find people working on this subject but the problem is i don't know at which level these people's studies are. Can you help me about this issue and suggest a way of making a list of universities?</p>
