Effect of different lead precursors on perovskite solar cell performance and stability

“…An important correlation between solar cell efficiency and lead precursor was previously reported for quantum dot sensitized solar cells using PbS as a light absorbing material. 32 In that case, a clear inuence of the lead precursor on the trap states was established.…”

ZnS/SiO2 Passivation Layer for High-Performance of TiO2/CuInS2 Quantum Dot Sensitized Solar Cells

“…This process was repeated for three times and the electrode is named as CuInS 2 /ZnS. Furthermore, SiO 2 coating was deposited by dipping the CuInS 2 /ZnS electrodes in ethanol solution containing 0.01 M tetraethylorthosilicate and 0.1 M NH 4 OH for 1 h. The as-fabricated electrode is termed as CuInS 2 /ZnS/SiO 2 .…”

“…Semiconductor quantum dots (QDs) based on II-VI group such as CdSe [1], CdTe [2], CdS [3], PbS [4], PbSe [5], and etc. have been extensively studied for QD sensitized solar cell (QDSSC) and photocatalysis applications, due to tunable band gap, hot electron injection, higher absorption coefficients, and multiple excition generation (MEG) [6,7].…”

Quantum Dot (QD) Sensitizer on the Surface of TiO2Film: Effect of Metal Salt Anions Dissolved in Chemical Bath on the Distribution Density of SILAR-Grown PbS QDs

“…A similar behavior in the case of PbS/CdS QD deposition was observed and reported recently. 20 More studies including other metal cations and anions are in progress for clarifying the mechanism and reaching a general conclusion for the SILAR-based chemical bath deposition of QDs.…”
