What is photocells?
answer 2 A photocell is a device that converts light energy into electrical output. From memory (?) selenium cells were the early photodetectors used on ancient photo equipment. (My Weston photo meter.) It was not too difficult to improve on the selenium photocells. Nowadays we are spoilt for choice for types of photocells, up to sophisticated photomltipliers, and solid state detectors that have completely replaced film for astronomy recording material.

How are photocells and thermocouple cells powered?
photocells are powered by the intensity of light. When we put the photocells in light the free electrons of the photocell move fast in other words they get the energy from light due to which their amplitude increases and they pass the electric charge rapidly hence the photocells are generate the power. Thermocouples are made of two different types of semi conductors when we heat the one end of the junction of thermocouple electric charge is produce this electric charge is a result of the movement of the free electrons as we increases the heat electric charge is also increase because the amplitude of the vibration of the free electrons is increases with the temprature

How do photocells convert light energy into electrical energy?
When photocells convert light energy into electrical energy many things happen. Most photocells contain silicon atoms. As long as a light shines on the photocell, electrons gain enough energy to move between atoms. The electrons are then able to move though a wire to provide electrical energy to a device, such as a calculator. Alek Peck Source Phisical Science textbook
