In the first lecture, he says, Photovoltaic = photo or light +electricity. Not to be confused with solar collectors.
Minhee, you answered your own question!
transformation of light in to electricity makes it photo (light) and voltaic (potential difference (voltage)or electricity )
When light fall on solar cell , a potential difference is created. Photo + voltaic
Photo= light in greek and voltaic in reference to Allessandro Volta an italian physicist and inventor of the electric battery. Solar cells convert sunlight energy into electricity while solar collectors deal with sun heat.

The rapid expansion in electrical technology at this time transformed industry and society. .... Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating ... Electricity and magnetism (and light) were definitively linked by James Clerk ..... description of electric potential difference that the term voltage sees.
Colin Murchie, Solar Energy Industries Association, Washington, D.C.. M. Dennis Mynatt ..... In the early 1800s, Italian Allesandro Volta produced electricity.
Agree with the Ghazi.Transformation of light in to electricity makes it photo (light) and voltaic (potential difference (voltage)or electricity)
