Abstrakt

A film of single-walled carbon nanotubes (SWNTs) can be flexible and stretchable transparent-conductive layer. By applying adequate doping, this film can be carrier-selective layers, i.e., electron-blocking-layers or hole-blocking-layers for perovskite solar cells. We have demonstrated the possibilities of nanotube films for CNT-Si solar cells and organic polymer solar cells. Here, we will emphasize the application of CNT films for organic-inorganic perovskite solar cells. We have demonstrated the replacement of ITO in inverted-type flexible perovskite solar cells, SWNTs/PEDOT:PSS/MAPbI3/PCBM/Al. Replacement of electron-blocking-layer and metal electrode in normal-type perovskite solar cells is demonstrated as well. The normal-type perovskite solar cell, composed of ITO/C60/MAPbI3/SWNTs, can achieve a PCE of 17 % with spiro-MeOTAD as dopant to SWNTs. This structure with a perovskite layer sandwiched by C60 and SWNTs can lead to the solar cells without hysteresis and with much improved air-stability. The effective passivation of the degradation of perovskite material by moisture can be achieved with C60 and SWNTs. More recent configuration is using a film of SWNTs for both anode and cathode electrode. With adequate doping, we can fabricate perovskite solar cells without ITO and metal electrode.
