“…FRET also occurs between quantum dots and organic dyes, which improves the photo capture 18 19 20 . Excitation of ERD could be non-radiative transfer to the acceptor dye through the electric field as the emission spectrum of the ERDs overlaps with the absorption spectrum of acceptors 21 22 23 . FRET efficiency between ERDs and acceptors mostly depended on the Förster radius (R 0 ).…”

In this paper, 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) has been used in interface modification of dye-sensitized solar cells (DSCs) with combined effects of retarding charge recombination and Förster resonant energy transfer (FRET). DCJTB interface modification significantly improved photovoltaic performance of DSCs. I–V curves shows the conversion efficiency increases from 4.27% to 5.64% with DCJTB coating. The application of DCJTB with combined effects is beneficial to explore more novel multi-functional interface modification materials to improve the performance of DSCs.

“…To achieve higher cell efficiency, a certain sensitizer is needed so as to absorb incident light as much as possible. Therefore, co-sensitization or multi branched strategy is applied to the organic dyes with complementary absorption spectra to obtain a broader and a more intense absorption band, thus increasing the performance of the DSSC [1,[29][30][31][32][33][34][35][36][37].…”

“…[1][2][3] The unique photophysical properties arise from the intramolecular charge-transfer between the electron-poor quadratic core and the fused electron-rich arene substituents. Previous studies have shown that squaraine dyes can be used in various applications such as (bio-)labelling, [4][5][6] photodynamic therapy, [7] dye-sensitised solar cells [8][9][10][11] and organic bulk heterojunction solar cells. [12] Despite numerous studies investigating the photophysical properties of squaraine dyes, the number of reports dealing with chiral analogues is limited.…”

Squaraine dyes are well knownf or their strong absorption in the visible regime. Reports on chiral squaraine dyes are, however,s carce. To address this gap, we here report two novel chiral squaraine dyes and their achiral counterparts. The presented dyes are aggregated in solution and in thin films. Ad etailed chiroptical study shows that thin films formed by co-assembling the chiral dye with its achiral counterparte xhibit exceptionalp hotophysical properties. The circulard ichroism (CD) of the co-assembled structures reaches am aximum when just 25 %o ft he chiral dye are present in the mixture. The solid structures with the highestr elative CD effect are achieved when the chiral dye is used solely as ad irector,r ather than the structural component. The chiroptical data are further supported by selected spin-filtering measurements using mc-AFM.T hese findings provideapromisingp latform for investigating the relationship between the dissymmetry of as upramolecular structure and emerging material properties rather than ac omparison between ac hiral molecular structure and an achiral counterpart.
