Printed semiconducting materials have great potential for a range of electronic applications, particularly where large active areas or flexible/stretchable devices are required. This class of materials is expanding rapidly, with specific interest currently in organic semiconductors and hybrid organic-inorganic lead-halide perovskites. As these materials begin to see commercial uptake, their short operational lifetime has become a critical limitation. NPL has developed a suite of tools for monitoring and understanding the degradation mechanisms affecting these devices in order to guide their ongoing development.
