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
The contraction of a muscle cell is an example of mechanical work.
Is there any video on how to replace a thermocouple on a gas fireplace
Charge-coupled device
why does the thermocouple have a very small heat capacity
a thermocouple is a sensor used to measure temperature under a wide variety of temperature ranges and condition
A CCD is a group of photocells. Photocells are cells that react to a broad range of light rays. CCD's convert light into an electric charge.

the photoelectrons released during photoelectric effect are used to generate electricity in photo cells
If your talking about a pilot in a furnace or fireplace, then its because the gasvalve is powered by a thermocouple. The thermocouple is 2 dissimilar metals fused together, when heated it produces a small amount of electricity to hold the valve open.

yes
because it does
It used to be Selenium, but modern photocells use silicon (Si).

The output of the thermocouple is linear.
Yes, thermocouple is used in fridges !
