|Project:||ESR-15: PhD at Merck Chemicals Ltd, United Kingdom|
|Topic:||Design, characterization and manipulation of electronic spin interactions for efficient and stable organic solar cells|
|Researcher (ESR):||Mr. Pierluigi Mondelli|
|Supervisors:||Dr. Graham Morse, Dr Priti Tiwana|
|C-supervisor:||Prof. dr. Carsten Deibel|
Design, characterization and manipulation of electronic spin interactions for efficient and stable organic solar cells
The researcher will advance OSC performance and improved OSC stability by the manipulation of electronic spin interactions in organic solar cells. The performance and stability of these polymers will be evaluated in bulk heterojunction solar cells (normal & inverted architectures). Expertise in device characterization by UV/Vis, EQE, photo-CELIV, TPV, AFM, profilometry and JV analysis will be developed throughout the project.
The researcher will be affiliated and registered with the Technical University Chemnitz and co-supervised by Prof. Carsten Deibel but will be placed in the industrial laboratory at Merck Chemicals in Southampton, UK and supervised by Dr. Graham Morse and Dr. Priti Tiwana. The researcher will spend 28 months on the preparation, optimization and characterization of OSC devices at Merck Chemical. As part of the evaluation device stability will be tested using defined ageing protocols. In addition to working at Merck Chemicals the project will include secondments at Technical University Chemnitz (5 month) to study charge extraction losses and Universität Würzburg (3 month) to evaluate spin-dependent recombination in OSCs.
The researcher will:
- Develop an understanding of spin processes in OSCs
- Fabricate, characterize and optimize OSCs
- Improved performance and stability by manipulating electron spin interactions
- Evaluation of stability of OSCs under ageing protocols
- Develop an understanding of charge carrier dynamics using photo-CELIV and TPV
The researcher will receive scientific training in:
• The laboratory scale printing equipment: doctor blades, spin-coaters, mini slot-die
• Surface characterization: AFM, profilometry, SEM
• Optoelectronic characterization: UV-Vis, EQE, photo-CELIV, TPV, solar simulators and equipment
• Fabrication and measurement of bulk heterojunction solar cells
He will also receive complementary training in: career development, public outreach, communication, entrepreneurial skills, organisation, networking, scientific writing, and meeting skills.
