Synergetic effect of TiO₂/ZnO bilayer photoanodes realizing exceptionally high V_OC for dye-sensitized solar cells under outdoor and indoor illumination

Abstract

Harnessing energy from the surrounding light using indoor photovoltaics has gained momentum to address the carbon footprint resulting from used and dead batteries. Dye-sensitized solar cells (DSCs) has emerged as...

Optoelectronic Characterisation and Theoretical Insight into the Binding Mechanism of D‐π‐A Triphenylamine‐Organic Dyes for Dye Sensitized Solar Cells

“…Notably, TPA‐based sensitizers have demonstrated exceptional efficiency both under outdoor and indoor light illumination conditions, as evidenced by several recent studies [3–7] . Motivated by these compelling findings, we have specifically chosen triphenylamine as the donor unit in our sensitizers for the present study [3,7,18–23] . Kitamura et al., for the first time, investigated a series of phenyl‐conjugated oligoene dyes as sensitizers for DSSC [24] .…”

“…[3][4][5][6][7] Motivated by these compelling findings, we have specifically chosen triphenylamine as the donor unit in our sensitizers for the present study. [3,7,[18][19][20][21][22][23] Kitamura et al, for the first time, investigated a series of phenylconjugated oligoene dyes as sensitizers for DSSC. [24] Compared with the dialkylamine, the improved donor strength, bathochromically shifted absorption spectrum and prevention of hydrogen-bonded dimer formation in triphenylamine derivatives resulted in a better PCE of 5.3 %.…”

Asymmetric dual species copper(ii/i) electrolyte dye-sensitized solar cells with 35.6% efficiency under indoor light

“…14,25,26 Recently Suraj and co-workers realized a record V oc of 1.27 V using [Cu(dmp) 2 ] 2+/+ electrolyte employing a bilayer TiO 2 –ZnO device architecture. 27…”

Facile Fabrication of an SnSx‐SnO2‐Decorated Cobalt Sulfide Film as an Effective Counter Electrode for Dye‐Sensitized Solar Cells

“…Dye-sensitized solar cells (DSSCs) have gained increasing attention for potential integration in portable electronic devices, owing to their facile fabrication, low cost, and high power conversion efficiency (PCE) under ambient illumination. [1][2][3] Typically, a DSSC comprises three essential components: the photoanode, electrolytes, and counter electrode (CE). [4] In particular, CE plays the two crucial roles in obtaining the high photovoltaic performance of DSSCs.…”
