Squaraine Planar-Heterojunction Solar Cells

Table 1

Photovoltaic performance of SQ01- and SQ02-based solar cells using as electron acceptor. Film thicknesses of 40 nm and 35 nm were used for SQ01 and SQ02, respectively. When ultrathin films were used, the thickness corresponds to 20 nm for both squaraine derivatives. The type of cathode utilized in the devices is also indicated.
