1. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells
Abstract : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. READ MORE

2. Polymer/polymer blends in organic photovoltaic and photodiode devices
University dissertation from Linköping : Linköping University Electronic PressAbstract : Organic photovoltaics devices (OPV) have attracted attentions of scientist for their potential as inexpensive, lightweight, flexible and suitable for roll-to-roll production. In recent years, considerable attention has been focused on new acceptor materials, either polymeric or small molecules, to replace the once dominating fullerene derivatives. READ MORE

4. Mass Transport Through Polymer Films: The Importance of Interfaces and Compatibility
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Different types of barriers are used in packaging to keep and protect products from the surrounding environment and are often essential for storing and transportation. Today, many barriers are made of different types of polymers, but since most polymers do not exhibit desired barrier properties on their own, combinations must be used. READ MORE
