AB  - Three near infrared (NIR) metal-free organic sensitizers (FNE32, FNE34, FNE36) 
      based on the thieno[3,4-b]pyrazine derivative have been designed and synthesized 
      for application in quasi-solid-state dye-sensitized solar cells (DSSCs). These 
      organic dyes demonstrate maximum absorption bands at 596-625 nm due to the 
      presence of the thieno[3,4-b]pyrazine derivative, which facilitates the 
      intramolecular electron transfer from the donor to the acceptor. 
      Quasi-solid-state DSSCs based on FNE34 display efficient photoelectric conversion 
      over the whole visible range extending into the NIR region up to 900 nm with 
      maximum incident monochromatic photon-to-electron conversion efficiency (IPCE) of 
      77%, yielding a short-circuit photocurrent density of 16.24 mA cm(-2) and a power 
      conversion efficiency of 5.30%. To the best of our knowledge, this is the highest 
      efficiency for quasi-solid-state DSSCs based on an organic NIR dye. When exposed 
      to one-sun illumination for 1000 h, the quasi-solid-state DSSC based on FNE34 
      exhibits good long-term stability with almost constant power conversion 
      efficiency.
