Inganäs, J. Puigmartí‐Luis and M. Campoy‐Quiles, Adv. Energy Mater., 2020, 10, 2001308. Microfluidic technologies are highly adept at generating controllable compositional gradients in fluids, a …

Efficient Exploration of the Composition Space in Ternary Organic Solar Cells by Combining High‐Throughput Material Libraries and Hyperspectral Imaging

A. Harillo‐Baños, X. Rodríguez‐Martínez and M. Campoy‐Quiles, Adv. Energy Mater., 2020, 10, 1902417. Organic solar cells based on ternary active layers can lead to higher power conversion efficiencies than corresponding binaries, and improved stability. The parameter space for optimization of multicomponent systems is considerably more complex than that of binaries, due to both, a larger …

High‐Throughput Multiparametric Screening of Solution Processed Bulk Heterojunction Solar Cells

A. Sánchez-Díaz, X. Rodríguez-Martínez, L. Córcoles-Guija, G. Mora-Martín and M. Campoy-Quiles, Adv. Electron. Mater., 2018, 4, 1700477. One of the major bottlenecks in the development of organic photovoltaics is the time needed to evaluate each material system. This time ranges from weeks to months if different variables such as blend composition, thickness, annealing, and additives …

Quantifying local thickness and composition in thin films of organic photovoltaic blends by Raman scattering

X. Rodríguez-Martínez, M. S. Vezie, X. Shi, I. McCulloch, J. Nelson, A. R. Goñi and M. Campoy-Quiles, J. Mater. Chem. C, 2017, 5, 7270–7282. We report a methodology based on Raman spectroscopy that enables the non-invasive and fast quantitative determination of local thickness and composition in thin films (from a few monolayers to hundreds of …
