There is a growing interest in organic solar cells in the photovoltaic field and research is mainly focused on improving the performance of these cells in terms of efficiency, lifetime, cost, and flexibility. This work is part of an ERANET-MED Euro-Mediterranean project entitled “New Indium- Free Flexible Electrodes” which aims at the modelling and realization of efficient flexible indium-free Transparent and Conductive Electrodes (TCE) for organic solar cells. Laboratories from France, Algeria, Morocco and Tunisia have committed to carrying out this project in collaboration. Nowadays, ITO [1] remains the most widely used transparent conductive electrode due to its excellent optical and electrical properties compared to other TCEs [2]. However, it has disadvantages, such as the scarcity of indium, its high cost and its mechanical properties poorly adapted to its use for flexible cells. One of electrode alternatives deals with in this project is a multilayer electrode. The objective is then to keep or to improve the opto-electrical performances, as well as the bending properties, without using indium.
