title: Squaraine-arylamine sensitizers for highly efficient p-type dye-sensitized solar cells.
abstract: New near-IR (NIR) squaraine dyes (p-SQ1 and p-SQ2) containing one and two anchoring groups were synthesized and used as the sensitizers of p-type DSSCs. The dye (0.113%) with two anchoring groups (p-SQ2) shows better performance than the dye (0.053%) with only one anchoring group (p-SQ1). Cosensitized p-type DSSCs using two dyes with complementary absorption were tested. They have broadened IPCE spectra and good cell performance.
