You may continue only if you feel comfortable with these concepts:
donor, acceptor, electron, hole, doping, built-in potential, “space charge” or “depletion region”
In this video, I’ll help you understand how doped semiconductors can be used to capture the abundant energy of the sun and convert it into useful electrical energy. This device is called a photocell or photovoltaics, and a large, flat system of photocells makes a solar panel. And you need to improve them to aid humanity. Go!
