1. 6. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Johansson André; [2021]
   Keywords : OSC; solar cells; active layer; polymer; degradation;

   Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE

3. 7. Synthesis and Characterization of Copper Halide Complex Materials

   University essay from KTH/Tillämpad fysikalisk kemi

   Author : Hiroki Tomita; [2021]
   Keywords : Copper halide complexes; Coordination polymers; Photoluminescence; Bidentate ligands; Applications of thin films; Kopparhalogenidkomplex; koordinationspolymerer; fotoluminiscens; bidentata ligander; tillämpningar av tunna skikt;

   Abstract : Energiförbrukning är ett hett ämne i världen idag, eftersom världens befolkning fortsätter att växa. Som ett resultat ökar också den globala energiförbrukningen snabbt och utsläppen av koldioxid därmed, vilket påverkar global uppvärmning och klimatförändringar. READ MORE

4. 8. Outdoor Stability Testing of Printed Organic Solar Cells for Indoor Applications

   University essay from Karlstads universitet

   Author : Cathrine Hekkala; [2020]
   Keywords : Solar energy; organic solar cell; printed; flexible; degradation; outdoor; indoor;

   Abstract : Renewable energy is required for a sustainable future and one way to meet this is with organic solar cells (OSCs). The OSC can be easily manufactured at a low cost, be lightweight and be used on flexible surfaces. READ MORE

5. 9. Electrical performance study of organic photovoltaics for indoor applications : with potential in Internet of Things devices

   University essay from Karlstads universitet

   Author : August Andersson; [2020]
   Keywords : Indoor light harvesting; Internet of things IoT ; Organic Solar cell; Organic photovolaic;

   Abstract : The evolution of the internet of things (IoT) opens the market opportunity for organic photovoltaic cells, especially for indoor applications where the lifetime of the organic cells is longer than outdoor. For example, IoT requires off-grid energy sources for many devices with low power consumption. READ MORE

6. 10. Performance evaluation and development of contact solutions for flexible organic solar cells

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Bastiaan Hamer; [2020]
   Keywords : Organic electronics; printed electronics; OPV; solar cell; renewable energy; Organisk elektronik; tryckt elektronik; OPV; solcell; förnybar energi;

   Abstract : In today’s society many non-renewable and environmentally harming energy sources are used to facilitate people’s everyday energy demands. This causes ecosystems to break down, global temperatures to rise, pollution and many more critical long lasting problems. READ MORE
