This book was released on 2012-04-23 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic photovoltaics (OPV) are a new generation of solar cells with the potential to offer very short energy pay back times, mechanical flexibility and significantly lower production costs compared to traditional crystalline photovoltaic systems. A weakness of OPV is their comparative instability during operation and this is a critical area of research towards the successful development and commercialization of these 3rd generation solar cells. Covering both small molecule and polymer solar cells, Stability and Degradation of Organic and Polymer Solar Cells summarizes the state of the art understanding of stability and provides a detailed analysis of the mechanisms by which degradation occurs. Following an introductory chapter which compares different photovoltaic technologies, the book focuses on OPV degradation, discussing the origin and characterization of the instability and describing measures for extending the duration of operation. Topics covered include: *Chemical and physical probes for studying degradation *Imaging techniques *Photochemical stability of OPV materials *Degradation mechanisms *Testing methods *Barrier technology and applications Stability and Degradation of Organic and Polymer Solar Cells is an essential reference source for researchers in academia and industry, engineers and manufacturers working on OPV design, development and implementation.

Download or read book Organic Solar Cells Electrodes Performance Enhancement and Degradation Mechanisms written by Reginald Jack Bauld and published by . This book was released on 2014 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis I focus on a number of aspects associated with the fabrication and characterization of organic photovoltaics. Specifically, my work focuses on evaluating solution processed graphene electrodes for use in organic photovoltaics, improving the performance of indium tin oxide transparent contacts by coating them with Au nanoparticles, and understanding the degradation pathways of poly(3-hexylthiophene-2,5-diyl): phenyl-C61- butyric acid methyl ester (P3HT:PCBM) organic solar cells. In my work on graphene electrodes for organic solar cells I worked out a relationship between the sheet resistance and the film transmittance that is useful to optimize such electrodes. Investigation of organic solar cell degradation in a controlled "70-70-70" test (i.e. keeping a device for 70 hours at 70oC under 70% humidity conditions) showed several possible pathways in which the active layer of these photovoltaics degrade. In addition to the typical morphological degradation, a strong increase in paramagnetic defect density in the active layer contributes to their degradation. Formation of paramagnetic defects in P3HT:PCBM layers was attributed by us to the creation of charge transfer complexes between P3HT and oxygen. Our attempts on improving indium tin oxide electrodes for their use in organic photovoltaics included a study of the effects of nucleation of Au-containing molecular nanoclusters. It was discovered that different types of Au nanoparticles with specific properties can be formed by annealing such clusters at different temperatures and under different conditions. This discovery was utilized to fabricate Au nanoparticle layers on indium tin oxide which were then utilized as plasmonic enhancement layers for organic solar cells.

Download or read book Interfacial Stability and Degradation in Organic Photovoltaic Solar Cells written by William Greenbank and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic photovoltaic (OPV) solar cells show great promise but suffer from short operating lifetimes. This study examines the role that the selection of materials for the hole extraction interface in inverted OPV devices plays in determining the lifetime of a device. In the first part of the study, the effects of thermal degradation were examined. It was found that devices containing MoO3 HTLs and silver top electrodes exhibit an open-circuit voltage (VOC)/fill factor (FF)-driven mechanism. Physical characterisation experiments showed that, with heating, the silver electrode undergoes de-wetting. With thin electrodes this can result in the catastrophic failure of the device. A fracture analysis study found that silver-containing devices experience an increase in adhesion of their top layers to the active layer due to interdiffusion between the layers. This interdiffusion may be related to the loss of VOC and FF in Ag/MoO3 devices through diffused species forming charge traps in the active layer. In the second part of the study, the effects of photodegradation in different atmospheres were studied. Some material-dependent effects were observed when the devices were aged in an inert atmosphere, including variations in projected lifetime. The effect of oxygen was to greatly accelerate degradation, and remove any of the material-dependence observed in the inert experiment, while humidity led to a substantial increase in the degradation rate of devices containing PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate). This study underlines the importance of considering device lifetime in device design, and choosing materials to minimise degradation.
