Green chemistry for organic solar cells

New “Green” Experiments for the Organic Chemistry Laboratories

1. Abstract: This project involves replacing a number of the currently used organic chemistry experiments with equally educational, yet more environmentally friendly experiments. Most of the fuels, materials, and medicines in our modern world have come about through advances in chemistry. Unfortunately, the production of these vital resources involves the formation of waste. However, new proces...

Organic Solar Cells

MRS BULLETIN • VOLUME 33 • JULY 2008 • www.mrs.org/bulletin Abstract Organic solar cells, based on polymer/fullerene-blend films, are advancing rapidly toward commercial viability. In this article, we review recent progress on two issues critical for technological applications: device photovoltaic efficiencies and processing technologies for high-throughput production. In terms of device effici...

Investigation of Organic Compounds as Photosensitizer for Dye Sensitized Solar Cells

Two organic compounds (SC-23=(E)-2-Cyano-3-(2,3-dimethoxyphenyl) acrylic acid and SC-25=(E)-2-Cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. They shows a short-circuit current density (Jsc) of 2.08 and 1.81 mA cm-2, an open circuit voltage (Voc)...

Synthesis and Application of Two Organic Dyes for Dye-Sensitized Solar Cells

In the present study, two new organic dyes based on indigo were prepared and used as sensitizers in dye-sensitized solar cells. To this end, indoxyl was utilized as the electron donor and cyanoacrylic acid as the electron acceptor anchoring groups. These dyes together with their corresponding intermediates were purified and characterized by FTIR, 1HNMR, 13CNMR, elemental analysis and UV-Visible...
