Postdoctoral Research Scientist in perovskite solar cells



The group of Prof. Carlos F. O. Graeff at Faculty of Sciences from São Paulo State University (UNESP), in Bauru (Brazil), is looking for 1 postdoctoral research scientist. The application deadline for the positions is 15/07/2022. The candidates are expected to design, produce and characterize perovskite solar cells (PSCs).

About the Project

The present project aims on comprehending the degradation mechanisms involved in PSCs, and on finding solutions to overcome the stability issues of these devices. Based on this premise, several chemical and physical aspects will be investigated which includes; synthesis of different perovskite light harvester materials, analysis of interfacial and defects phenomena, search for optimal electron and hole transport layers materials, use of promising novel techniques for materials and devices characterization and novel device configurations. These investigations will converge to the primary objective of this work which consists of proposing more stable and more efficient PSCs.

Key project aims

I. To optimize perovskite compositions in order to minimize defects during crystallization and thin-film deposition steps.
II. To design novel electron and hole transport layers as alternatives for the currently low stable used materials.
III. To characterize the structure, morphology and optical properties of nanomaterials as active components in PSCs;
IV. To study defects and their effects on PSCs by using advanced spectroscopic and electrical techniques such as photothermal deflection spectroscopy (PDS) and photo-CELIV.

Requirements and how to apply

– Ph.D. in Physics, Materials Science & Engineering, Chemistry, or related areas.
– Experience in fabrication and characterization of perovskite solar cells is necessary.
– Experience on a variety of film deposition methods (blade-coating, roll-to-roll, etc) will be positively evaluated.
– Previous experience with the characterization techniques PDS or CELIV is a plus.
– English knowledge (fluent in writing and speech).

Each selected candidate will receive a Post-Doctoral fellowship from the São Paulo Research Foundation (FAPESP) in the amount of R$ 8.479,20 monthly and a research contingency fund, equivalent to 10% of the annual value of the fellowship which should be spent in items directly related to the research activity

Candidates should contact Prof. Carlos F. O. Graeff (carlos.graeff@unesp.br) with a brief statement of research interest/cover letter, a CV, and contact information of 2-3 references. Students in their final year of Ph.D. training are encouraged to apply.
