  1. 21. Effects of the interfaces in planar hybrid lead trihalide perovskite solar cells with n-type and p-type inorganic charge transport layers

    University essay from KTH/Energiteknik

    Author : Olivier Jaques Henri Fournier; [2018]
    Keywords : ;

    Abstract : Perovskite-solceller är en framväxande och lovande tunnfilmsteknik, som uppnådde hög effektivitet på en ofantlig kort tid. Den nuvarande arkitekturen i cellen, som innefattar titanoxid och Spiro-OMeTAD (en organisk förening) som laddningstransportlager (CTL), saknar stabilitet och visar hysteretiskt beteende. READ MORE

  3. 22. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Jonatan Fast; [2017]
    Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

  4. 23. Perovskite solar cells

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Jonas Stenberg; [2017]
    Keywords : solar cells;

    Abstract : Perovskite solar cells (PSC) performance has risen rapidly the last few years with the current record having power conversion efficiency (PCE) of 22.1 %. This has attracted a lot of attention towards this alternative solar cell that can be manufactured with less energy and toxic material than traditional silicon solar cells. READ MORE

    Abstract : .... READ MORE

  6. 25. Structural Effects on Degradation and Photophysical Behaviour of Methylammonium Lead Iodide Perovskites

    University essay from Lunds universitet/Fysiska institutionen

    Author : Elin Källman; [2016]
    Keywords : Physics and Astronomy;

    Abstract : Perovskites have proven to have very promising properties applicable in future higher efficient technological devices such as light emitters and solar cells. In further development of perovskite solar cell devices there are however serious material drawbacks such as instability and toxicity, causing the perovskite research community to question if and how these obstacles can be overcome.
