Usage of Low Cost Digital Camera for Detecting of Silicon Solar Cell Electroluminiscence

摘要

Luminescence is the property of some substances with a suitable electron structure to emit electromagnetic radiation in a near or visible spectrum. It is caused by the quantum transition of electrons in atoms from higher energy levels to lower levels after receiving a certain amount of energy after, for example, in the form of ultraviolet light (photoluminescence) or electrical energy (electroluminescence).
