dye-sensitized solar cells present promising low-cost alternatives to the conventional silicon (si)-based solar cells. the counter electrode  generally consists of pt deposited onto fto plate. since pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. carbon nanotubes  have shown significant properties such...

The efficient capture and conversion of solar energy into a usable form is a significant research target. Dye-sensitized systems, such as dye-sensitized solar cells (DSSCs) and watersplitting dye-sensitized photoelectrochemical cells (WSDSPECs), utilize high surface area metal oxide scaffolds sensitized with a molecular light-absorbing dye to harvest sunlight and convert it into an electrical p...

The emergence of quantum dot-sensitized solar cells (QDSSCs) has provided an alternative way to harvest sunlight for energy conversion. Among all the QDSSCs, cadmium chalcogenide (CdX, X1⁄4S, Se or Te) based QDSSCs have gained a significant interest due to their easy fabrication, low cost and high performance. However, their performance still does not match with that of their dye-sensitized sol...

During the last four centuries, there have been extensive research activities looking for green and clean sources of energy instead traditional (fossil) in order to reduce accumulation gases environmental pollution. Natural dye-sensitized solar cells (DSSCs) are one most promising types photovoltaic generating at a low cost. In this study, DSSCs were collected experimentally tested using differ...

The charge transfer (CT) properties of photosensitizers largely determine the photovoltaic performances dye sensitized solar cells (DSSCs). Thus, understanding CT is key to further improving DSSCs. We herein investigated underlying relationship between molecular structures and using resonance Raman (RR) spectroscopy density functional theory (DFT) calculations. RR combined with DFT calculations...

High extinction coefficients and easily tunable spectral properties of π conjugated donor-acceptor dyes are of superior advantage for the design of new metalfree organic sensitizers for applications in dye-sensitized solar cells. Ultrafast transient absorption spectroscopy on the femtosecond and nanosecond time scales provided deep insights into the dependence of charge carrier dynamics in full...

Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode  generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes  have shown significant properties such...

We fabricated a highly efficient (with a solar-to-electricity conversion efficiency (η) of 8.1%) Pt-free dye-sensitized solar cell (DSSC). The counter electrode was made of cobalt sulfide (CoS) nanoparticles synthesized via surfactant-assisted preparation of a metal organic framework, ZIF-67, with controllable particle sizes (50 to 320 nm) and subsequent oxidation and sulfide conversion. In con...
