Calculating Structure-Performance Relationship in Organic Solar Cells

Temperature-dependent Schottky barrier in high-performance organic solar cells

Organic solar cells (OSCs) have attracted great attention in the past 30 years, and the power conversion efficiency (PCE) now reaches around 10%, largely owning to the rapid material developments. Meanwhile with the progress in the device performance, more and more interests are turning to understanding the fundamental physics inside the OSCs. In the conventional bulk-heterojunction architectur...

Discotic materials for organic solar cells : Effects of chemical structure on assembly and performance

Discotic materials have attracted remarkable interest for application in organic solar cells. We analyze a series of phenyl substituted hexa peri hexabenzocoronenes (HBCs) with residue modifications blended with perylenediimide (PDI) as donor material. The effect of differing alkyl chain lengths of 6, 8, 12 and 16 carbon atoms, introduction of a triple bond linker between HBC core and residual ...

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...

Dual plasmonic nanostructures for high performance inverted organic solar cells.

Polymer-fullerene-based bulk heterojunction (BHJ) solar cells have many advantages, including low-cost, low-temperature fabrication, semi-transparency, and mechanical fl exibility. [ 1 , 2 ] However, there is a mismatch between optical absorption length and charge transport scale. [ 3 , 4 ] These factors lead to recombination losses, higher series resistances, and lower fi ll factors. Attempts ...
