ORGANIC PHOTOVOLTAICS
Extended models for polar interfaces in bulk heterojunctions, balance of excitonic and charge transfer states
Methods: second-order algebraic construction (ADC(2)) and TD-DFT using long-range corrected functionals
Collaboration partners: Itamar Borges, Jr. (Instituto Militar de Engenheria, Rio de Janeiro, Brazil), Sergei Tretiak (Los Alamos National Laboratory, USA), Adélia Aquino (Texas Tech University, Texas, USA)
