We have designed and synthesised two new carbazole based self-assembled molecules as hole-selective layers (HSLs) in p–i–n perovskite solar cells achieving high efficiency stability.
Abstract The performance of five hole‐transporting layers (HTLs) is investigated in both single‐junction perovskite and Cu(In, Ga)Se 2 (CIGSe)‐perovskite tandem solar cells: nickel oxide (NiO x ,), copper‐doped :Cu), NiO +SAM, :Cu+SAM, SAM, where SAM the [2‐(3,‐6Dimethoxy‐9H‐carbazol‐9yl)ethyl]phosphonic acid (MeO‐2PACz) self‐assembled monolayer. devices correlated to charge‐carrier dynamics at HTL/perovskite interface limiting factors these HTLs are analyzed by performing time‐resolved...
Abstract We present monolithic copper–indium–gallium–diselenide (Cu(In,Ga)Se 2 , CIGSe)-perovskite tandem solar cells with air- or N -transferred NiO x :Cu without self-assembled monolayer (SAM) as a hole-transporting layer (HTL). A champion efficiency of 23.2%, open-circuit voltage (V <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:msub> <mml:mi> </mml:mi> <mml:mrow> <mml:mi mathvariant="normal">o</mml:mi> mathvariant="normal">c</mml:mi> </mml:mrow>...
In this contribution we are comparing the commonly used RbF post deposition treatment (PDT) of CIGS absorber layers to an alternative RbCl-PDT. The RbCl-PDT leads similar improvements cell efficiency as fluorine does. While effect procedure on open circuit voltage is not strong it in case RbF-PDT, could reach even higher fill factor. Furthermore investigating impact RbCl degradation already RbF-treated layers. We find that additional can decrease by air-, moisture- and low...
