Abstract
For the first time, based on the known optical constants of the materials (refractive index and extinction coefficient), calculations of optical losses in glass/transparent conducting oxide (TCO)/CdS/ CdTe solar cells have been carried out taking into account reflections at the interfaces and absorption in the TCO (it can be indium tin oxide (ITO) or SnO2:F) and CdS layers. It has been shown that the losses caused by reflections at the interfaces result in lowering the short-circuit current by ∼9 % whereas absorption in the TCO and CdS layers with the typical thicknesses lead to losses of 15-16% for glass/ SnO2/CdS/CdTe, and 22-24% for glass/ITO/CdS/CdTe solar cells. At 100% photoelectric conversion in the CdTe absorber layer, this corresponds to a loss in short-circuit current by ∼3 mA/cm2 due to reflection, and 4-7 mA/cm2 due to absorption at the glass/SnO2(or ITO)/CdS stack. Losses due to absorption in float glass and low-iron glasses are 3.3-3.5% and 0.6-0.7%, respectively.
