Definitions
- the invention relates generally to the production of photovoltaic cells, and in particular of organic photovoltaic cells (usually designated by the acronym OPC for "Organic Photovoltaic Cells").
- organic photovoltaic cell is meant, within the meaning of the present invention, photovoltaic cells of which at least the active layer consists of organic molecules.
- Organic cells represent a real interest in the field of photovoltaics. Indeed, the possibility of replacing the organic semiconductors generally used in photovoltaic cells makes it possible to increase the number of feasible systems and therefore the possibilities of use. The development of organic photovoltaic cells, and even more the development of marketable organic photovoltaic cells currently represent a major challenge.
- the PEDOT: PSS layer is placed on the ITO (English acronym for “Indium Tin Oxide”: indium tin oxide) and under the active layer, for example based on P 3 HT: PCBM (as illustrated in Figure 1), while in reverse structure photovoltaic cells, the layer of PEDOT: PSS is printed on the active layer and under the upper electrode serving as anode.
- Photovoltaic cells with reverse structure have the advantage of having better air stability than cells with conventional structure, and in addition of having higher conversion yields.
- conversion efficiency of a photovoltaic cell is meant, within the meaning of the present invention, the ratio of the maximum electric power delivered by the cell to the incident light power, for a spectral distribution and a given intensity.
- the applicant has developed a method for manufacturing a photovoltaic cell, in which all the layers applied to the substrate coated with a transparent electrode are applied by jet printing. ink, which makes it possible to customize the layers thus applied. It is already known to use inkjet printing to produce certain layers of organic photovoltaic cells.
- the present invention relates to a photovoltaic cell comprising:
- a first interfacial layer of zinc oxide or zinc oxide doped with aluminum said first interfacial layer covering said cathode
