TiO2- CuI Nanoparticle /Ru Solid State Dye-Sensitize Solar Cells

Abstract

In this work solid state dye sensitized solar cell (SSDSSC) type (ITO / TiO2/ Ru / CuI / Ag) is fabricated. The thin films are prepared by pulse laser deposition (PLD) technique under the vacuum pressure of 3×10−3 mbar and annelid at 450 oC. In this technique Nd:YAG laser at 1064 nm wavelength with (200 , 500 , 800) pulsed was used. It was noticed from (I-V) characteristics of the solar cell that the photocurrent collected from the TiO2 (NP) is increase as the number of laser pulses increase. The conversion efficiency of TiO2 is increased from 2.115% up to 5.654% and for CuI from 1.73 % to 5.19 % when the number of pulses increase from 200 up to 800.

Progress on Electrolytes Development in Dye-Sensitized Solar Cells

“…However, efficiencies that were reported in subsequent studies did not improve any further, and they ranged from 1–5.5% at most [340,341,342,343,344]. In 2014, Amalina and Rusop conducted an investigation into the properties of CuI thin films [340].…”

“…Taha et al demonstrated the effect of pulse laser deposition (PLD) for both TiO 2 and the CuI thin films on the performance of ss-DSSCs [342]. The thin films were fabricated by PLD under 3 × 10 −3 mbar of vacuum pressure and annealed at 450 °C.…”

“…The study found a direct relationship between the photocurrent from the TiO 2 and the laser pulses that were used during fabrication; the more laser pulses applied, the higher the photocurrent at the TiO 2 layer. This led to a leap in the conversion efficiencies of TiO 2 , from 2.115% up to 5.654% and for CuI from 1.73% to 5.19% upon increasing the number of pulses from 200 to 800 [342].…”
