Two novel symmetrical blue squaraine sensitizers were synthesized, which exhibit panchromatic light harvesting and a record efficiency over 6% with J sc exceeding 14 mA cm −2 , and V oc over 620 mV under 1 sun. Their color, low cost, easiness of synthesis, and relatively high photo- and thermal stab...

Summary:Two novel symmetrical blue squaraine sensitizers were synthesized, which exhibit panchromatic light harvesting and a record efficiency over 6% with J sc exceeding 14 mA cm −2 , and V oc 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 commercial applications. A new series of low cost dibranched symmetrical blue-greenish squaraines showing interesting photovoltaic properties and photostabilities is reported.
