General description

ICBA is a C60 derivative that can be synthesized from C60 and indene. It is an acceptor material with shallow lowest occupied molecular orbital(LUMO) which can be used to enhance the performance of polymeric solar cells(PSCs).
The performance of indene-C60 bisadduct (ICBA) as organic solar cell (OSC) has been described in a study. Simple preparation and high solubility inorganic solvents renders ICBA as an efficient substitute to [6,6]-phenyl-C61 butyric acid methyl ester (PCBM).

Application

A ternary bulk heterojunction system (BHJ) may be fabricated with ICBA low band gap polymer, for IR sensitized organic solar cells. 1-3ICBA/thiazolo-thiazolo donor polymer blend may be used to enhance the charge generation in BHJ solar cells.
ICBA can be used with poly(3-hexylthiophene)(P3HT) as an active layer which can be used in the fabrication of organic solar cells(OSCs).ICBA in combination with thiazolo-thiazolo can be used as a donor. It can be blended with PCBM for photovoltaic based application.
