Abstract :
A method for the fixation of colloids by an ion-layer-gas-reaction-“ILGAR”-oxide layer is presented. The embedding of CdS nano-particles in an ILGAR-ZnO/Zn(OH)2-matrix is confirmed by transmission electron micrographs (TEM); the composition of the layer surface is analyzed by X-ray photoelectron microscopy (XPS). When these particles are fixed by an ILGAR-oxide layer on top of a solar cell the observed absorption and fluorescing properties of CdS nano-particles offer the possibility to reduce the absorption loss in the window layer. This is shown for a Cu(In,Ga)(S,Se)2-“CIGSSe”-based solar cell with an additional top CdSparticle/ILGAR-ZrO2-layer as a first example. The improvement of the device performance is proven by J(V)-characteristics and the external quantum efficiency.
