The novel single-walled carbon nanotubes (SWCNT) have high current carrying capacity and electrical conductivity,and the preparation method is relatively simple,making them important for application in perovskite solar cells.A perovskite solar cell with a structure of Glass/FTO/ZnO/MAPbI3/SWCNT/Au was designed using SCAPS-1D software.The effects of SWCNT band gap and acceptor doping concentration in hole transport layer,ZnO donor doping concentration in electron transport layer,perovskite absorption layer thickness and defect state density on cell performance were investigated.The results showed that after optimization,the open circuit voltage,short circuit current density,filling factor and photoelectric conversion efficiency of perovskite solar cells were 1.18V,25.58mA/cm2,83.76% and 25.42%,respectively.
