Solar Energy in Grad School

Hey I was wondering if anyone could help me with grad programs in Solar energy. I am currently a computer science major in college and I want to go into solar energy in the future but I do not know what to study exactly in grad school and also if you knew any programs that are similar to what I am looking for, please link them below.P.S. I want to specifically go into solar energy not renewable energy as a whole

Not sure if this fits your criteria:

That is one pricey program. One year resident is about $35K and out of state $50K.

Why not try first to see if you can get a job in the field of solar. That way you will know if it’s a field that you enjoy. Or, look for internships in this field while still an undergraduate. Don’t go to graduate school until you know exactly what you want to study and why.
