Efficient passivated phthalocyanine-quantum dot solar cells

Abstract

The power conversion efficiency of CdSe and CdS quantum dot sensitized solar cells is enhanced up to 45% for CdSe and 104% for CdS by passivation with an asymmetrically disulfide substituted phthalocyanine.

The influence of phthalocyanine aggregation in complexes with CdSe/ZnS quantum dots on the photophysical properties of the complexes

“…In particular, complexes of QDs and tetrapyrrole molecules were of great interest due to their diverse application in many fields ranging from latest third generation solar cells [1–3] to photodynamic therapy (PDT) [4–10]. Currently, practically all PDT drugs are based on tetrapyrrole molecules.…”

Interfacial Engineering for Quantum‐Dot‐Sensitized Solar Cells

“…Severals tudies have explored the QD/dye interactions [96] and interfacial charge-transfer mechanisms [97] between ruthenium dyes and QDs, and clear improvements in their photovoltaic performance has been observed in various QD/dye systems, such as PbS/N719, [98] CdS/N3, [99] CdSe/N3, and CdSe/Ru505. [100] Because there is significant overlap between the absorption spectra of QDs and ruthenium dyes, light harvesting would be more efficient if the photonsw ere captured selectively and complementarily.T herefore, some other dyes, such as JK-216, [101] squaraine dye (SQ), [102] DBF (Figure3b), [103] and zinc phthalocyanines, [104] have been extensively applied to extend the photoresponseo fQ Ds.…”

Photovoltaic Properties of Bi2S3 and CdS Quantum Dot Sensitized TiO2 Solar Cells

“…There are several architectures that incorporate QDs into photovoltaic devices [23][24][25][26][27][28][29][30][31][32]. One of them, Quantum Dots Sensitized Solar Cells (QDSSCs), typically consist of TiO 2 NPs acting as highly porous electron collector sensitized with QDs employed to harvest solar light [27][28][29][30][31][33][34][35][36]. The theoretical efficiencies predicted for this type of cell are as high as 44% [37].…”
