Hybrid solar cells using solution-processed TiO2/Sb2S3 bilayer as electron transport layer
Efficient inverted hybrid solar cells using poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) bulk heterojunction as active layers and TiO2/Sb2S3bilayers as electron transport layers (ETL) have been prepared in ambient air. The microstructural, photoelectronic, and electrochemical characteristics on these cells have been investigated. Photoluminescence measureme...

Solvent-induced textured structure and improved crystallinity for high performance perovskite solar cells
We demonstrate an environment-friendly solvent treatment that leads to a dramatic performance improvement of perovskite solar cells, with power conversion efficiency as high as 18%, with good stability. The solvent not only improves perovskite film morphology and crystallinity, but also, at proper growth conditions, leads to the formation of a self-induced textured structure on a dense layer; th...

Simultaneously enhanced J(sc) and FF by employing two solution-processed interfacial layers for inverted planar perovskite solar cells
Interface engineering has been proved to be a practical strategy to enhance power conversion efficiency (PCE) and stability of perovskite solar cells. Recently approaches involving ultra-thin layer deposition and vacuum-processing, while improving PCE, increase the processing complexity, and thus the overall cost. In this paper, we demonstrate a high-efficiency inverted planar perovskite solar c...

High efficiency organic solar cells based on amorphous electron-donating polymer and modified fullerene acceptor
The current manuscript examines the structure and property relationship of amorphous conjugated polymer based bulk heterojunction solar cells. Solvent vapor annealing (SVA) is used to optimize the morphology. It is seen that the structure order of the blended thin film does not change but phase separation becomes prominent. The space charge limited current and admittance spectroscopy reveals that ...

[J Mater Chem A]Indacenodithiophene: A Promising Building Block for High Performance Polymer Solar Cells
Harvesting energy directly from sunlight using photovoltaic technology has become an essential component of future global energy production. Although silicon-based inorganic materials have still played a dominant role in the market, problems for inorganic materials-based solar cells mainly lie in (1) high cost of production and technical difficulties in the fabrication of large-ar...

Dithiafulvene-based organic sensitizers using pyridine as the acceptor for dye-sensitized solar cells
Three dithiafulvene-based metal-free organic sensitizers all using pyridine as the acceptor but with different π-bridges of phenyl (DTF-Py1), thienyl (DTF-Py2) and phenyl-thienyl (DTF-Py3) have been designed, synthesized and used as photosensitizers for dye-sensitized solar cells (DSCs). Introducing thienyl unit into the π-bridge, as well as extension of the π-bridge can dramatically improve th...

Plasmonic enhanced dye-sensitized solar cells with self-assembly gold-TiO2@core–shell nanoislands.
Decorating TiO2 photoanode of dye-sensitized solar cell (DSSC) with silver or gold nanoparticles has been shown to be an effective approach for enhancing device performance via the plasmonic effects. Here, we show for the first time that the same approach can be adopted simultaneously for both the photoanode and the counter-electrode of a DSSC but operates with different enhancement mechanism. I...

Theoretical design of push-pull porphyrin dyes with π-bridge modification for dye-sensitized solar cells
A series of new D-π-A porphyrin-based dyes, based on GY50 by utilizing 2-cyanoacrylic acid anchoring group and modifying the π bridge with thiophene, furan and/or vinyl groups, has been designed and investigated for screening efficient sensitizers in dye sensitized solar cells (DSSCs). The efficiency of the designed dye molecules is analyzed through various parameters. The absorption spectra of ...

A planar dithiafulvene based sensitizer forming J-aggregates on TiO2 photoanode to enhance the performance of dye-sensitized solar cells.
A newly planar dithiafulvene sensitizer (DTF-C4) trending to form J-aggregates on the surface of mesoporous TiO2 by simply rinsing with a poor solvent acetonitrile was synthesized. We further show that the self-assembled J-aggregates optimized the TiO2surface utilization, enhanced the light harvesting ability by broadening and red-shifting the absorption, and suppressed the electron recombinatio...
