Industrial viability of single-component organic solar cells

A dumbbell-like A-D-A molecule for single-component organic solar cells.

A dumbbell-like A-D-A molecule, triad 1, containing a dithienosilole-dibenzothiadiazole donor unit and two fullerene acceptor units was designed and synthesized. Triad 1 shows good solubility, thermostability, light absorbance, and film-forming capability. Solar cells using 1 as the active layer gave a PCE of 0.4%.

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...

Comparison of organic solar cells and inorganic solar cells

The fluctuating price of energy, due to a variety of reasons ranging from geo-political constraints to national and international economic issues, and the fact that these energy resources are finite, can be seen as the main incentives to make a transition to a clean energy society. Solar energy is just one of many ways to make this transition a reality, and of the raft of clean energy technolog...

Organic solar cells: An overview

Organic solar cell research has developed during the past 30 years, but especially in the last decade it has attracted scientific and economic interest triggered by a rapid increase in power conversion efficiencies. This was achieved by the introduction of new materials, improved materials engineering, and more sophisticated device structures. Today, solar power conversion efficiencies in exces...
