International audienceHarvesting energy from their environment could be an ideal solution for an autonomous function of numerous small electronics. Organic Photovoltaic (OPV) cells are a promising technology for next generation photovoltaic cells combining novel properties such as light weight, flexibility, or color design with large-scale manufacturing with low environmental impact. Furthermore, the OPV cells are good solution for Indoor applications. In this field, DRACULA TECHNOLOGIES (DT) has developed inkjet printing organic solar cells and modules. The great advantage of inkjet printing as a digital technology is the freedom of forms and designs, large area organic modules with different artistic shapes. The stability of OPV cells are critical element for up-scaling and commercialization of this technology. To evaluate the stability and lifetime of the DT modules, the ISOS-D-1 (shelf lifetime) protocol is applied for 175 days. The devices were stored under dark ambient conditions and a LED light source is used for the periodical characterizations
