The objective of this investigation was to shed light on the nature of interaction of different organic dyes and an inorganic dye, Ruthenium (II) polypyridine complex, with TiO2 nanoparticles. TiO2 is commonly deployed as an efficient energy transfer electrode in dye sensitized solar cells. The efficiency of dye sensitized solar cells is a function of the interaction of a dye with the electrode...

We report the charge transfer dynamics for CdSe quantum dot (QD) sensitized solar cells. The effect of QD sensitization mode in recombination kinetics has been measured and their implications in solar cell performance analyzed.

A counter-electrode comprised of large-pore sized mesoporous carbon exhibits low charge transfer resistance in iodide/triiodide redox electrolyte, thus liquid and quasi-solid dye sensitized solar cells show 8.18% and 3.61% solar to electric energy conversion efficiency, respectively.

Dye sensitized solar cell (DSSC) being one of the main focus in area of photovoltaic after silicon solar cell, modeling and estimating their parameters becomes important for their analysis and enhancement in their performance. We have proposed an analytical approach having no approximation for extracting various parameters of DSSC using a well known Lambert W-function technique. The model used ...

Perovskite Solar Cells In article number 2300072, Michael Grätzel, Jingshan Luo, and co-workers show that the carrier transport layer plays a critical role in high-efficiency stable perovskite solar cells (PSCs). They developed CsPbBr3 quantum dots sensitized mesoporous TiO2 (CPB-TiO2), which enhances crystallinity, phase stability, reduces non-radiative recombination PSCs. As result, CPB-TiO2 ...

3,4-Ethylenedioxythiophene and bis[2-(2-methoxyethoxy)ethoxy]thiophene bridged donor-acceptor molecules for dye-sensitized solar cells have been synthesized, one of which achieved a solar-to-energy conversion efficiency of 7.3%, compared to 7.7% optimized for N719 dye.
