What do you think of photovoltaic and solar energy field as a field to study?

Question

I m considering this field for master's degree

I mean i find that it will be a recommended field more and more in the future but i m afraid that it might be narrow

Answer 1

I think that energy technology will be one of the really good engineering fields for the next few decades.  

Concerning the narrowness of it, all areas where you get a master's degree narrow focus but increase depth of knowledge.  It gets even narrower if one gets a PhD, but the depth is much greater.
