We have investigated a wavelength conversion material (WCM) based on Eu(III)-cored complex as a new coadsorbent. WCM absorbs the light at shorter wavelengths and emits the light at longer wavelengths, and acts as a spacer for breakup of π-stacked aggregates. It can improve electron injection yield and Jsc. As a result, the short-circuit photocurrent density (Jsc) by 10 %, and overall efficiency by 14 % was increased than NKX2677 based solar cell under standard global AM 1.5 solar conditions, and the photovoltaic performance of η = 7.78 %. The synthesis and characterization of a new coadsorbent material based on lanthanide(III)-cored complex for highly efficient dye-sensitized solar cells will be presented. |
