Calculating the Energy Gab of Photo Resistance Using Temperature Variation

In this thesis photo resistor (CdS) was used to calculate the energy gab using simple electrical method, it was found that to be and and electrical conductivity of photo resistor equal to and (I.V) characteristic was studied under the influence of temperature variation and constant polarization angle of irradiation (𝜃 ,also the of relation versus angle 𝜃 at constant voltage was considered with temperature variation. Different relation was plotted and the results were discussed for the resistance which obtained versus temperature.
