The calculation of the power conversion efficiency (PCE) value for a bulk heterojunction (BHJ) organic solar cell is complex due to the wide number of parameters involved in the processes. This study focuses the attention on the molecular parameters involved into the open circuit voltage and the PCE definitions and in particular on the electronic coupling and on the lowest unoccupied molecular orbital (LUMO) of the acceptor. A simplified model system composed by a polymer as donor and a novel class of molecules (9,9\u2032-bisfluorenylidene derivatives) as acceptor has been proposed as prototype to simulate the BHJ organic solar cell interface. Several substituents on different positions are tested and the chemical nature/position of substit...
