  1. 16. Syntes och karakterisering av ogiftiga organiska metall halid halvledare för solceller

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Oskar Dahlin; [2015]
    Nyckelord :Solar cells; Solar energy; Lead free perovskites; Semiconductors; Organic metal halide;

    Sammanfattning : The endeavor to have more efficient solar cells and as environmentally beneficial as possible are the driving forces for this work. The way to reach this is by research to better the understanding of the mechanisms and parameters that govern the performance of solar cells. LÄS MER

  3. 17. Lamination of Organic Solar Modules

    Master-uppsats, Biomolekylär och Organisk Elektronik; Tekniska högskolan

    Författare :Sofie Kalldin; [2014]
    Nyckelord :Organic solar modules; Lamination; PEDOT:PSS; Ethylene Glycol EG ; Diethylene Glycol DEG ; Polyethylene Glycol PEG ; Roll to roll process R2R ;

    Sammanfattning : As the Worlds energy demand is increasing we need more of our energy to be generated from resources that affect the climate as little as possible. Solar power could be the solution if there were solar panels with a less energy demanding production than the established silicon based solar modules. LÄS MER

    Sammanfattning : A spin-cast silicone membrane has been successfully bonded between two injection-molded microstructured plastic discs. This sandwich structure creates a useful platform for mass production of microfluidic systems, provided that the bonds are leakproof. LÄS MER

  5. 19. Determination of electro-optic tensor coefficientsof organic thin film using Fabry-Parotinterferometric setup

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Osama Khan Amjad Iqbal; [2013]
    Nyckelord :;

    Sammanfattning : In this Masters thesis, a method for independent characterization of nonlinear electro-optic (EO) tensor components (r13, r33) of organic polymers is presented. Organic non-linear optical (NLO) polymers provide low cost and easily process able photonic devices. LÄS MER

  7. 20. Polymer structures for photovoltaics using colloidal self-assembly, thermal nanoimprinting and electrohydrodynamic annealing

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik

    Författare :Ivan Huuva; [2012]
    Nyckelord :electric field; nanoimprinting; nanoimprint lithography; nil; electrohydrodynamic; ehd; polymer; organic electronics; photovoltaics; solar cells; patterning; self-assembly; colloidal crystal; imprint annealing; embedded annealing; patterning;

    Sammanfattning : The efficiency of an organic photovoltaic cell depends mainly on its morphology where an exciton has to migrate to a p-n junction to create a photocurrent. Therefore the distance from the bulk of the cell to a junction interface should not exceed the diffusion length of the exciton. LÄS MER
