Survey of co-adsorbent for DN350 in zinc oxide dye-sensitized solar cell

• Better performance of DN350 than D149 in the presence of cholic acid on zinc oxide.
• The best performance of DN350 in the presence of ursodeoxycholic acid.
• Bathochromic shift of UV–vis absorption band of DN350 in the presence of ursodeoxycholic acid.

DN350 exhibited better performance than D149 in zinc oxide dye-sensitized solar cell in the presence of cholic acid (CA). The performance of DN350 was improved in the order of cholic acids: ursodeoxycholic acid (UDCA) > chenodeoxycholic acid (CDCA) > CA. This result could come from the bathochromic shift of the UV–vis absorption band of DN350 on zinc oxide to improve short-circuit photocurrent density.

Ursodeoxycholic acid (UDCA) was the best co-adsorbent for DN350 in zinc oxide dyesensitized solar cell due to the bathochromic shift of the UV–vis absorption band.Figure optionsDownload as PowerPoint slide
