Abstract: Third-generation solar cells are projected to achieve high energy conversion efficiency and, at the same time, have low production costs. Despite achieving high efficiencies, research on degradation processes under continuous use and ambient conditions remains limited, mostly due to the absence of affordable-commercially available degradation setup. To overcome it, we detailed the fabrication, assembly and test of an affordable and easy-to-setup experimental apparatus for stability and degradation study of solar cells technologies. The apparatus was designed following the ISOS protocol consensus and was validated using Organic Solar Cells (OSCs) devices with standard P3HT:PC61BM active layers, enabling the acquisition of degradation trends consistent with literature benchmarks. Three ISOS protocols for indoor testing were employed (ISOS-L-1, ISOS-D-1, and ISOS-T-2), along with one outdoor protocol, ISOS-O-2. Our proposal presents a simple and accessible experimental setup to expand the adoption of degradation testing, laying the basis for universal and more systematic methods of assessing device lifetime. Its cost-effective design also ensures direct integration into existing protocols, further expanding access to long-term evaluation processes.
