  1. 21. AFM Studies of Pristine PCBM Changes Under Light Exposure

    University essay from

    Author : Erin Chambers; [2013]
    Keywords : PCBM; light; elastic modulus;

    Abstract : Organic solar cells promise a cheap and easy alternative to silicon photovoltaics, but there are many problems that must be solved before they can be a stable and efficient substitute. One such problem is the degradation of solar cells under exposure to light and oxygen. READ MORE

  3. 22. Printed Antennas on Paper

    University essay from Avdelningen för elektronikkonstruktion

    Author : Reza Moossavi; [2013]
    Keywords : Conductive ink; paper; antenna design; microstrip antenna; dipole; Itoh s balun;

    Abstract : Ink-jet printing (IJP) using conductive inks, has gained the attention of scientistsand researchers during the past decades. Solar Cells (SCs), Radio FrequencyIdentication (RFID), E-papers and antennas are only some of the applicationsfor which IJP is being applied. IJP facilitates printing complex antenna structureswith a good resolution. READ MORE

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

    University essay from Institutionen för fysik

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

    Abstract : 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. READ MORE

  5. 24. Transient photocurrent measurements on Polymer Solar Cells

    University essay from Lunds universitet/Fysiska institutionen

    Author : Unn Dahlén; [2012]
    Keywords : Physics and Astronomy;

    Abstract : Organic solar cells made of polymers are an attractive alternative to the conventional solar cells which are commercially used today. The polymer solar cell is cheap to produce, due to the high absorption coefficients which limits the needed thickness of the material and due to the simple manufacturing process, which doesn’t demand high temperatures.

  6. 25. Comparative Study of APFO-3 Solar Cells Using Mono- and Bisadduct Fullerenes as Acceptor

    University essay from Institutionen för fysik, kemi och biologi

    Author : Yu-Te Hsu; [2010]
    Keywords : Polymer solar cell; bisadduct fullerene; photoluminescence quehching;

    Abstract : The urgent need for new, sustainable energy source intrigues scientists to provide the solution by developing new technology. Polymer solar cell appears to be the most promising candidate for its low cost, flexibility, and massive producibility. READ MORE
