ICBA (full form 1’,1’’,4’,4’’-tetrahydro-di[1,4]methanonaphthaleno[5,6]fullerene-C60, CAS number 1207461-57-1) or IC60BA is a fullerene derivative with two indene functional groups.
Indene-C60 bisadduct was designed to increase the open circuit of P3HT solar cells due to the higher lying LUMO level (0.17 eV higher than PCBM), in order to significantly increase the power conversion efficiency [1,2]. The indene functional groups disrupt the conjugaction of C60 fullerene and act as electron-donating groups. These properties reduces the electron affinity of ICBA. As a result its lowest unoccupied molecular orbital level is higher. When ICBM is used with P3HT within a solar cell there is a larger difference between the HOMO of P3HT donor and the LUMO of ICBA acceptor, resulting in an improved open-circuit voltage (Voc). It can also be used as an electron cascade acceptor to improve charge transport in devices.

Polymer-Fullerene Bulk Heterojunction Solar Cells
Polymer-fullerene bulk heterojunction (BHJ) solar cells are based on blends of semiconducting polymers and fullerene derivatives, such as PCBM. It is described as a bulk heterojunction as it involves a blend of two materials with differing energy band gaps, forming a dispersed, interpenetrating network.
