effect. when any light (i.e. the sunlight in this case) is incident upon a material surface, the electrons present in the 'valence band' absorb energy and, being excited, jump to the conduction band and become free. these highly excited, non-thermal electrons diffuse, and some reach a junction, e.g.
. if this gap is very large, the material is known as insulator, i.e. glass, ceramic, wood, etc. if the gap is almost zero, then the material is considered as metal, i.e. copper, aluminium, iron, etc., which are known as good conductors of electricity. however, if the bandgap is somewhere intermediate...
