iPHOS

The ultimate goal of iPHOS is the demonstration of large-area (>1 cm²) organic photovoltaics (OPVs), covering the full development spectrum from material evaluation at the laboratory scale to the demonstration of integrated systems, with lifetime and performance surpassing current technologies under both laboratory and real indoor conditions. In addition, diversified lighting scenarios will be examined, not limited to direct sunlight, but also corresponding to realistic household lighting conditions and commercial lamp types. This will be achieved as follows: iPHOS will capitalize on recent advances in the development of high-bandgap conjugated polymers and electron-accepting materials with long exciton lifetimes, tunable energy levels, and low synthetic complexity (SC). The final materials will serve as active layers aimed at minimizing energy offsets between donor/acceptor components. On one hand, minimizing energy level offsets through the combination of materials with long exciton lifetimes will reduce non-radiative losses (Voc_non-rad), while maintaining high power conversion efficiency. On the other hand, using materials with low SC will enable their facile synthesis in multi-gram or even kilogram quantities, a prerequisite for effective optimization and large-scale production of organic photovoltaics. Furthermore, the iPHOS project will address device architecture design, photophysics, morphological characterization, device physics, and large-scale printing.
