Explanation:

All the statements are incorrect.
Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons.
Solar thermal power generation systems collect and concentrate sunlight to produce the high temperature heat needed to generate electricity.

option is correct answer because photo built directly convert solar energy into electricity while solar thermal energy conversion unit solar power II II into thermal energy again thermal energy converted into electricity
