چکیده
We report an inexpensive TiO2 based quantum dot solar cell (QDSSC) with improved power conversion efficiency prepared by simple techniques. Barium doped zinc sulfide has been successfully deposited on cadmium dots (QDs) successive ion layer adsorption and reaction (SILAR) technique. The is utilized as a passivation in the QDSSC, which helped better charge separation. copper (Cu2S) reduced graphene oxide FTO was used counter electrode. developed QDSSC showed superior performance when tested AM 1.5 simulator using sulfide/Polysulfide electrolyte. photoconversion of FTO/TiO2/CdS/BaZnS/Cu2S-Graphene than that FTO/TiO2 /CdS/ZnS/Cu2S-Reduced Graphene oxide.

Restricted charge recombination process in PbS quantum dot sensitized solar cells by different coating cycles of ZnS films
The relatively low power conversion efficiency (PCE) of quantum dot sensitized solar cells (QDSSCs) is attributed to charge recombination at the interfaces. Charge recombination process could be suppressed by coating the QD layer with a wide band gap semiconductor such as ZnS, which acts as a blocking layer between the QDs and hole transport material (HTM). In present study, to improve PCE of P...
متن کاملUncovering the role of the ZnS treatment in the performance of quantum dot sensitized solar cells.
Among the third-generation photovoltaic devices, much attention is being paid to the so-called Quantum Dot sensitized Solar Cells (QDSCs). The currently poor performance of QDSCs seems to be efficiently patched by the ZnS treatment, increasing the output parameters of the devices, albeit its function remains rather unclear. Here new insights into the role of the ZnS layer on the QDSC performanc...

متن کاملSILAR Sensitization as an Effective Method for Making Efficient Quantum Dot Sensitized Solar Cells
CdSe quantum dots were in situ deposited on various structures of TiO2 photoanode by successive ionic layer adsorption and reaction (SILAR). Various sensitized TiO2 structures were integrated as a photoanode in order to make quantum dot sensitized solar cells. High power conversion efficiency was obtained; 2.89 % (Voc=524 mV, Jsc=9.78 mA/cm2, FF=0.56) for the cells that sensitized by SILAR meth...
