Optimizing Polymer Tandem Solar Cells

Advanced Materials, 2010
Optimized tandem solar cells based on wide-and small-bandgap polymer semiconductor cells reach an efficiency of 4.9%. In this tandem cell the short-circuit current exceeds that of the current-limiting subcell. The recombination layer that connects the two subcells does not impose important losses.

Multi-junction Polymer Solar Cells [PDF]

, 2008
We discuss the materials challenges for increasing cell efficiencies of polymer solar cells via the route of stacking several cells on top of each other in multi-junction solar cells. For such cells, the recombination layer between the two sub cells is crucial.

Plasmonic Polymer Tandem Solar Cell

ACS Nano, 2011
We demonstrated plasmonic effects in an inverted tandem polymer solar cell configuration by blending Au nanoparticles (NPs) into the interconnecting layer (ICL) that connects two subcells. Experimental results showed this plasmonic enhanced ICL improves both the top and bottom subcells' efficiency simultaneously by enhancing optical absorption.

Hybrid Nanorod-Polymer Solar Cells

Science, 2002
We demonstrate that semiconductor nanorods can be used to fabricate readily processed and efficient hybrid solar cells together with polymers. By controlling nanorod length, we can change the distance on which electrons are transported directly through the thin film device.

Polymer–Fullerene Composite Solar Cells

Angewandte Chemie International Edition, 2007
AbstractFossil fuel alternatives, such as solar energy, are moving to the forefront in a variety of research fields. Polymer‐based organic photovoltaic systems hold the promise for a cost‐effective, lightweight solar energy conversion platform, which could benefit from simple solution processing of the active layer. The function of such excitonic solar

Stretchable Polymer Solar Cell Fibers

Small, 2014
Power yourself up: a sweater made from solar cells! Stretchable and wearable fibers are shown to be highly efficient polymer solar cells. Their stable energy conversion efficiency variation is below 10% even after 1000 bending cycles or stretching under a strain of 30%. These fibers can easily be woven into fabric from which any type of clothing can be

Diketopyrrolopyrrole Polymers for Organic Solar Cells

Accounts of Chemical Research, 2015
Conjugated polymers have been extensively studied for application in organic solar cells. In designing new polymers, particular attention has been given to tuning the absorption spectrum, molecular energy levels, crystallinity, and charge carrier mobility to enhance performance. As a result, the power conversion efficiencies (PCEs) of solar cells based

Polymer Solar Cells

2017
Polymer solar cells are typically based on bulk-heterojunction active layers containing polymers and fullerene or other molecules, which are solution-processable. The easy processing is the biggest difference comparing to the small molecule-based solar cells.
