Second law of thermodynamics states that the total entropy of a closed system always increases over time.
Entropy of a system tends to increase over time
Heat cannot be completely converted into work
Efficiency of a heat engine is always less than 100%
Heat flows from a hotter body to a colder body
Example: A cup of hot coffee left in a cold room will eventually cool down as heat flows from the hotter coffee to the colder r
Zeroth law of thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

Solar cells convert sunlight into electricity using photovoltaic effect.
Solar cells are made of semiconductor materials like silicon.
When sunlight hits the solar cell, it excites electrons in the material.
The excited electrons create an electric current, which can be used as electricity.
Solar cells are often connected in arrays to generate more power.
Common types of solar cells include monocrystalline, polycrystalline,...
