Allgemeine Beschreibung

cis-Bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)ruthenium(II) (N3 dye) is a ruthenium polypyridyl based complex that can be used as a sensitizer. It is a highly stable polymer in which the photocurrent decreases with an increase in the concentration of N3 dye.[1][2][3]

Anwendung

Efficent DSSCs for Direct Conversion of Sunlight to Electricity
N3 dye can be coated on electrodes for improving the sensitivity of the dye sensitized solar cells (DSSCs) which can further enhance the power conversion efficiency (PCE).[4][5][6]

Questions

1–4 of 4 Questions  

  1. What are the advantages of dye solar cells?

    1 answer

    1. Dye solar cells (DSCs) are 3rd generation solar cells with the promise of high efficiency combined with low production costs.

      Helpful?

  2. What are the disadvantages of dye solar cells?

    1 answer

    1. The major disadvantage to the dye solar cell design is the use of a liquid electrolyte, which has temperature stability issues. The electrolyte can freeze at low temperatures and expand at higher temperatures.  It the electrolytes freezes, power production would cease, and it could potentially lead to physical damage.  If the liquid expands at higher temperatures, sealing the panels would be difficult.

  4. What can cause degradation of the dye solar cell?

    1 answer

    1. Dye solar cells degrade from ultraviolet radiation.  For this reason, the barrier may include UV stabilizers and/or UV absorbing luminescent chromophores (which emit at longer wavelengths) and antioxidants to protect and improve the efficiency of the cell.
