Abstract

Two novel sym. blue squaraine sensitizers I and II, were synthesized, which exhibit panchromatic light harvesting and a record efficiency over 6​% with Jsc exceeding 14 mA cm-​2, and Voc over 620 mV under 1 sun. Their color, low cost, easiness of synthesis, and relatively high photo- and thermal stability open up the way for com. applications.
