Yet another PhD graduate in the group!

Nanopto newest PhD graduate,  Dr. Xabier Rodriguez, defended succesfully last monday (November 19) . Congratulations! Dr. Rodriguez has defended with merits her thesis named “Development of organic solar cells by combinatorial methods“. We extend the congratulations to his supervisors prof. Mariano Campoy-Quiles, from ICMAB-CSIC in Barcelona.


The thesis was defended partially remotely by videoconference, as is being custom in the last months. Science does not stop and we are adapting to the new circumstances. Great job Xabier!



The optimization of organic solar cells entails the exploration of complex parametric landscapes in which several interrelated features determine the photovoltaic performance. In this thesis, we develop a high-throughput experimental framework based on the generation of lateral parametric gradients to accelerate the screening of organic solar cells. We first introduce Raman imaging as a spectroscopic tool to characterize the heterogeneity of the gradients in combination with photocurrent imaging. Then, we implement advanced solution-processing methods to generate solid-state gradients and demonstrate their potential in the combinatorial screening of binary and ternary organic photovoltaic blends. Finally, we develop a synergic workflow combining high-throughput experimental screening and machine-learning algorithms to predict the photocurrent phase space of organic photovoltaic blends.
