This project seeks to explore the potential of biopolymers-surfactant-chromophores solid-state co-assemblies as sustainable material to harvest photon energy exploiting triplet-excitons of chromophores. Triplet-excitons can be harvesting by converting in to photo-emissive singlet excitons via triplet-triplet annihilation upconversion (TTA-UC). Solid-state TTA-UC materials have potential to increase the efficiency of solar cells by upconverting transmitted sub-band gap photon to band gap responsive photons.

TTA-UC bioplastics are unique combination of TTA-UC chromophores fabricated into biopolymers that can upconvert the triplet-state upon low energy excitation with high efficiency in aerated conditions. The current project will focus on developing TTA-UC bioplastics for sustainable upconversion of near infrared (NIR) light in to visible light in the solid-state, followed by intergration with photovoltaic (PV) devices.

In particular, the candidate will be in charge of synthesizing new ionic organic chromophores as annihilator for optically active fabrication in bioplastics and photophysical characterization. Hence, the focus of the candidate’s research will be on the organic synthesis, photochemistry and photophysical characterization in solution and solid-state.

The Sustainable Molecualr Systems group, has a broad expertise on the design, synthesis and characterization of organic chromophores for triplet-state harvesting via triplet-triplet annihilation based photon upconversion (TTA-UC) with recent publications from the group are e.g. J. Am. Chem. Soc. 2022, 144, 3706; J. Mater. Chem. C 2021,9, 11655; J. Phys. Chem. B 2021, 125, 6255; Chem. Soc. Rev., 2020,49, 6529; J. Am. Chem. Soc. 2018, 140, 10848; Nat. Commun., 2016, 7, 12689.

This is a multidisciplinary and transversal project and the candidate will be part of a team formed by several researchers.

Main tasks of the candidate

  1. Organic synthesis of organic chromophores as annihilators for TTA-UC and fabrication into bioplastics.
  2. PV device design for integration with bioplastics and performance analysis.

Requirements

The fellow should have an internationally recognized Masters degree (or equivalent) in a relevant discipline (Chemistry, Chemical Engineering, Organic Chemistry).

The ideal candidate should have a strong background in organic chemistry. Knowledge of photochemistry is a merit.

About Sustainable Molecular Systems Group

The Sustainable Molecular Systems Group group at ICMAB is using modern synthesis tools to develop new materials for energy storage, energy upconversion, solar energy, sensors and molecular electronics. We also build demonstration devices to illustrate the function of our new materials. The group is interdisciplinary and focus in addition to traditional organic synthesis on development of advanced flow chemistry tools, lab automation, devices for thermal energy storage materials and photoconversion. The group is supported by the European Research Council (ERC), the Catalan Institute of Advanced Studies (ICREA), la-Caixa Foundation, the European Union and ICMAB through the Severo Ochoa excellence project.

We value a diverse and inclusive work environment where all team members have excellent opportunities for learning and contributing.
