TLDR
In this article, a variety of experimental techniques were combined to resolve the structure of fullerene and polymer domains on the nanometer scale, and it was experimentally identified that the phase-separated domain size as well as the percolation of both hole and electron-conducting phases is crucial to improve the power conversion efficiency of organic solar cell devices.About:

Journal ArticleDOI
Charge Photogeneration in Organic Solar Cells
TL;DR: The backbone of a π-conjugated polymer is comprised of a linear series of overlapping pz orbitals that have formed via sp2 hybridization, thereby creating a conjugated chain of delocalized electron density, which dictates the electronic characteristics of the polymer.
Journal ArticleDOI
Morphology of polymer/fullerene bulk heterojunction solar cells
TL;DR: In this article, the authors combined and summarized the experimental findings on this nanomorphology-efficiency relationship and proposed a bicontinuous interpenetrating phase structures within these blend films.
Journal ArticleDOI
Recent Progress in Polymer Solar Cells: Manipulation of Polymer:Fullerene Morphology and the Formation of Efficient Inverted Polymer Solar Cells
TL;DR: In this article, a review of polymer morphology is presented with respect to solvent selection and various annealing processes, which facilitates the formation of optimal percolation paths and therefore provides a simple approach to improve photovoltaic performance.

TL;DR: The design and fabrication of three-dimensional multifunctional architectures from the appropriate nanoscale building blocks, including the strategic use of void space and deliberate disorder as design components, permits a re-examination of devices that produce or store energy as discussed in this critical review.
Journal ArticleDOI
Organic photoresponse materials and devices
TL;DR: It is expected that this systematic analysis of photoresponse materials and devices could be a guide for the better understanding of structure-property relationships of organic materials and provide key clues for the fabrication of high performance organic optoelectronic devices.

Polymer photovoltaic cells : enhanced efficiencies via a network of internal donor-acceptor heterojunctions
TL;DR: In this paper, the carrier collection efficiency and energy conversion efficiency of polymer photovoltaic cells were improved by blending of the semiconducting polymer with C60 or its functionalized derivatives.
Journal ArticleDOI
Photoinduced electron transfer from a conducting polymer to buckminsterfullerene.
TL;DR: Because the photoluminescence in the conducting polymer is quenched by interaction with C60, the data imply that charge transfer from the excited state occurs on a picosecond time scale.

Small molecular weight organic thin-film photodetectors and solar cells
TL;DR: In this paper, the double heterojunction was proposed to confine excitons within the active layers, allowing substantially higher internal efficiencies to be achieved, and a full optical and electrical analysis of the double-heterostructure architecture leads to optimal cell design as a function of the optical properties and exciton diffusion lengths of the photoactive materials.
