The Absorption Factor of the Wafer for Normal Incidence
The absorption factor of the wafer is defined as the fraction of incident electromagnetic irradiance that is absorbed by the wafer.The absorption factor is derived from refractive index and the extinction coefficient of the wafer theoretically.Based on our analysis ,the absorption efficiency of the muti-layer configuration will be higher than the individual one at the same condition.
