Prof. dr. Esther Alarcón Lladó is the group leader of the 3DPV group at NWO-I AMOLF since 2016 and professor of nanoelectrochemistry at the University of Amsterdam (UvA) since 2023. Alarcón Lladó has a strong track record in the development of new materials and energy conversion principles for sustainable energy generation with a unique complimentary approach based on photonics, spectroscopy and (photo)electro–chemistry. She is renowned for her work on photonic waveguiding in solar cells. Apart from the many contributions on the field of nanowire PV, she has introduced hyperuniform disorder nanopatterning as an efficient light management platform for thin film PV and demonstrated the strongest light absorption in thin c-Si. Additionally, her group is known for the high degree of spatio-temporal control over ions/ion complexes in solution and their chemistry. Within this framework, she has developed highly promising synthesis pathways for photovoltaic materials (IIII-V, perovskites and metals) in line with circular chemistry, as it minimizes raw material and energy consumption. Her group has developed distinctive in-situ/operando scanning probe microscopes for the investigation of dynamic nanoscale phenomena at electrified solid-solid and solid-liquid interfaces.
