Grant number: 14/20410-1
Support Opportunities:Regular Research Grants
Duration: February 01, 2015 - January 31, 2017
Field of knowledge:Physical Sciences and Mathematics - Physics - Condensed Matter Physics
Principal Investigator:Francisco Carlos Lavarda
Grantee:Francisco Carlos Lavarda
Host Institution: Faculdade de Ciências (FC). Universidade Estadual Paulista (UNESP). Campus de Bauru. Bauru , SP, Brazil


We intend to perform a theoretical study with organic materials for use in active layers of solar cells through methods of electronic structure calculation at ab-initio quality and semiempirical levels. The aim is to obtain polymeric electron donor materials with apropriate values for the highest occupied electronic state as well the energy difference between this level and the lowest unoccupied electronic state, which are closely related to the final degree of efficiency and stability that the device can achieve. We also intend to investigate whether these materials tend to exhibit improved transport properties. The studies comprise (i) copolymers of similar monomers and (ii) optimization of the frontier electronic levels of known donor polymers subjected to chemical modifications. For these systems, we also intend to (iii) study the internal reorganization energy and the exciton binding energy (properties associated with the transport and generation of charge carriers) and (iv) appropriate methodologies for prediction of the bandgap, which is an international collaboration in progress.
