Internal resistance in cells and solar cells arises from distinct mechanisms. In dry cell batteries, internal resistance is primarily due to the conducting materials used, which facilitate electron flow. Conversely, solar cells exhibit internal resistance influenced by the semiconductor properties and the quantum mechanical behavior of electrons at the junction of different semiconductor materials. Understanding these differences is crucial for optimizing performance in both applications.
PREREQUISITESEngineers, researchers, and students in the fields of electrochemistry, semiconductor technology, and renewable energy who are looking to deepen their understanding of internal resistance in energy storage and conversion systems.
I think the difference is that a dry cell battery, being made up of conducting material, whereas a solar cell is a semiconductor. There are free electrons in a conductor. The conductivity of the semiconductor depends on the quantum mechanical behaviour of electrons at the junction of two different semiconductor materials.Cheman said:What causes internal resistance in the following:
A) A Cell,
B) A Solar Cell?
Is it not just the same thing? Thanks in advance.
