Need Advice on Choosing Between تخصص تحويل حراري and تخصص تحويل كهروضوئي in Renewable Energies

Hello, everyone! I’m currently trying to decide between two specializations in renewable energies: تخصص تحويل حراري (thermal conversion) and تخصص تحويل كهروضوئي (photovoltaic conversion).

I would appreciate it if anyone with experience in these fields could share some insights on:

• The career prospects in each field.
• The kind of work and projects involved in both specializations.
• Which field has more growth opportunities, especially in [mention your country or region, if relevant].
• Any advice on what to consider before making this decision.

Thanks in advance for your help!
