The
Thermal Voltage is the relationship between the flow of electric current and electrostatic potential across a p-n junction. The
thermal voltage depends on absolute temperature T.

This creates a potential difference between the valence band and conduction band, which is the thermal voltage, VT. Also, it is dependent on temperature, as expected, as the greater the temperature, the greater the number of conduction electrons and holes produced, and thus the greater the voltage, between them.Mar 22, 2012

If the temperature T is measured from absolute zero, the quantity kT has the dimensions of an energy and is usually called the thermal energy. At 300 K (room temperature), kT = 0.0259 eV.
