Application

BT-CIC is a highly efficient, ultra-narrow bandgap, NIR absorbing, non-fullerene acceptor, designed to use in high performance organic photovoltaic devices.
A recently reported tandem cell, employing BT-CIC as the non-fullerene acceptor and PCE-10 as donor for the back cell showed an PCE of 15%.

Device performance:
Tandem [Front] (170 nm DTDCPB:C70 + ARC) [Back]PCE-10:BTCIC (1:1.5, 75 nm)
Jsc=13.3 ± 0.3 mA/cm2
Voc=1.59 ± 0.01 V
FF=0.71± 0.01
PCE=15.0% ± 0.3%
ARC:an antireflection coating
