The world needs a new source of energy, an unspillable source.

What should I do to start my career in the solar and alternative energy field?

I have a Bachelors in Material Science and Engineering. No particular solar experience. I’ve been looking to get a masters at Univ. of Texas or another Texas University, but I’m not sure which degree would best help me get a job, if at all. What should be my next steps, I’ve been researching for a few days.
How would I go about getting a entry job in the solar industry, what type should i look for?
