This master thesis investigates the possibilities of using a Semi-flexible terrestrial solar panel in a low Earth orbit space environment. A Semi-flexible solar panel is a sandwich of polymer films with the solar cells in between, these layers are laminated to create the end product. This, for space, new process is applicable to all major solar cell types. It enables a wide range of possible designs and could result in a drastically lower price, shorter production time and a lighter and smaller end product. By using system engineering methodology, the risks of Semi-flexible solar panels in space are identified after which the major risks have been tested. The risks investigated in this report are: outgassing, temperature cycling, vacuum UV radiation, charged particle radiation and the stiffness in deployed and stowed position. The results show no red flags for a seven-year 600 km Earth orbit. A transmission degradation of 10% is observed, resulting in lower power output for the selected material. When entering higher orbits, the amount of radiation leads to delamination and potentially no power output. When comparing the Semi-flexible solar panel to a conventional solar panel, a price difference of factor 4 and a power output difference of 33% is expected. The vast price difference shows the potential for the concept, but further investigation is needed to find out if the transmission degradation could be mitigated and whether designs comply with stiffness and vibration requirements.
