Journal ArticleDOI
Roll-to-roll fabrication of polymer solar cells
TL;DR: This work reviews the roll-to-roll processing techniques required to bring the magnificent 10-10 targets into reality, using quick methods with low environmental impact and low cost and highlights some new targets related to processing speed, materials, and environmental impact.
Journal ArticleDOI
Roll‐to‐Roll fabrication of large area functional organic materials
TL;DR: A review of roll-to-roll (R2R) compatible applications for thin-film transistors can be found in this article, where the current status of R2R application within some of the existing research fields such as organic photovoltaics, organic thin film transistors, light-emitting diodes, polymer electrolyte membrane fuel cells and electrochromic devices.
Journal ArticleDOI
Advanced materials and processes for polymer solar cell devices
TL;DR: The rapidly expanding field of polymer and organic solar cells is reviewed in the context of materials, processes and devices that significantly deviate from the standard approach which involves rigid glass substrates, indium-tinoxide electrodes, spincoated layers of conjugated polymer/fullerene mixtures and evaporated metal electrodes in a flat multilayer geometry as mentioned in this paper.
Journal ArticleDOI
25th Anniversary Article: Rise to Power – OPV‐Based Solar Parks
TL;DR: It is found that a high voltage installation where solar cells are all printed in series enables an installation rate in Watts installed per minute that far exceed any other PV technology in existence.
