Hybrid solar cells based on light absorbing semiconducting polymers infiltrated in nanocrystalline TiO2 electrodes, have emerged as an attractive concept, combining benefits of both low material and processing costs with well controlled nano‐scale morphology. However, after over ten years of research effort, power conversion efficiencies remain around 0.5%. Here, a spectroscopic and device based investigation...
In this review we highlight the contribution of pump‐probe spectroscopy to understand elementary processes taking place in organic based optoelectronic devices. The techniques described in this article span from conventional pump‐probe spectroscopy to electromodulated pump‐probe and the state‐of‐the‐art confocal pump‐probe microscopy. The article is structured according to three fundamental processes...
