In this contribution, we report on investigations of THz emission from Cu(In,Ga)Se_2 layers, deposited from a single copper-deficient sputtering target. Emission from Cu(In,Ga)Se_2 layer surface and from multilayer structure with transparent ZnO layers were studied. It was determined that additional undoped ZnO layer reduces the amplitude of THz emission, while additional n-type ZnO layers increase the emission amplitude again. This effect can be attributed to stronger electric field in the heterostructure between p-type Cu(In,Ga)Se_2 and n-type ZnO layers.
