Diketopyrrolopyrrole Polymers for Organic Solar Cells
Accounts of Chemical Research, 2015Conjugated 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

Nanostructured polymer solar cells
2008 IEEE International Reliability Physics Symposium, 2008Polymer solar cells generally contain a low bandgap p-type conjugated polymer as photosensitizer and an inorganic or organic n-type semiconductor as electron acceptor. We investigated two nanostructured composites of the complementary semiconductors: nanometer-scale blends and interpenetrating nanorod arrays.

Translucent Polymer Solar Cells
ECS Transactions, 2009The recent developments on the construction of translucent cathodes for the application of tandem or multi-junction organic solar cells are reviewed in this report. The translucent cathode plays a major role in determining the efficiency of translucent solar cells by controlling the intensity of incident light absorption at the photoactive layer of ...

Biodegradable polymer solar cells
Solar Energy Materials and Solar Cells, 2008Abstract Polymer photovoltaic devices were prepared using a biodegradable poly- l -lactic acid (PLLA) substrate loaded with nanoclay in an attempt to improve the thermal properties and possibly reduce permeation of water and oxygen. The nanoclay-loaded PLLA substrates were prepared by compounding and extrusion.

Polymer semiconductor solar cells
1978 International Electron Devices Meeting, 1978We report the first solar cell whose junction is formed by a polymer-semiconductor interface. Open circuit voltages, V oc > 0.7 V have been observed on cells consisting of a thin film of polymeric sulfur-nitride, (SN) x , deposited on GaAs. This is an enhancement of more than 40% over the V oc commonly measured with metal-GaAs solar cells.
