Electron Blocking Layer

This paper deals with the study of light conversion efficiency of organic photovoltaic cells with an inkjet-printed graphene oxide layer. The graphene oxide is used in this experiment as a hole-extracting, electron blocking layer in bulk heterojunction organic solar cells based on DPP(TBFu)2:PC60BM blend. It is also studied the influence of the GO reduction (chemically, by UV radiation and by annealing) on the final efficiency of photovoltaic conversion. Power conversion efficiency and the transport of charge carriers are evaluated by measuring of current-voltage characteristics and mainly by impedance spectroscopy analysis. In this regard, using of graphene oxide and its reduced form showed negative influence on the device performance caused by an inefficient charge carrier collection at the short-circuit condition.

The present manuscript is dedicated to In free transparent conductive andflexible heterostructure electrodes. The new electrodes correspond todielectric/metal/dielectic (D/M/D) multilayer structures deposited under vacuum. In thepresent work, after a fast review of the general properties of D/M/D electrodes using Ag asmetal, we then develop the study of D/Cu/D multilayer structures. We propose to substituteCu to Ag, because it is far cheaper. However, Cu having tendency to diffuse into manydielectrics it is difficult to obtain stable electrodes. We show that using Cu:alloys, i.e. Cu:Niand Cu:Al, as metal it is possible to decrease significantly the Cu ions diffusion and toincrease significantly the stability of the multilayer electrodes with Cu. Finally, we show thatwhen these electrodes are used as anode in organic photovoltaic cells, they can allowachieving efficiency similar to that obtained with ITO.
