Dithieno[3,2-b:2′,3′-d]pyran-containing organic D–π–A sensitizers for dye-sensitized solar cells†
Abstract
We describe herein the design and synthesis of two new organic regioisomeric D–π–A sensitizers incorporating the dithieno[3,2-b:2′,3′-d]pyran (DTP) unit. The dye-sensitized solar cells (DSSCs) based on these two dyes exhibit impressive power conversion efficiency.
