Their color, low cost, easiness of synthesis, and relatively high photo- and thermal stability open up the way for commercial applications.Panchromatic symmetrical squaraines: a step forward in the molecular engineering of low cost blue-greenish sensitizers for dye-sensitized solar cellstext::journal::journal article::research article
