Abstract

The appearance of kinks in the fourth quadrant of current-voltage curves decreases dramatically the efficiency of photovoltaic solar cells (SCs). These S-shaped J-V curves have been successfully reproduced using different lumped-parameter equivalent circuits, composed of two or more diodes. In this work, Mazhari's three-diode equivalent circuit is used to model the S-shaped J-V curves of perovskite SCs numerically simulated with Silvaco ATLAS TCAD. The simulated cell structure is fluorine-doped tin oxide (FTO)/TiO2/MAPbl(3)/2,2 ,7,7 -tetrakis [N,N-di (4-methoxyphenyl) amino]-9, 9 -spirobifluorene (Spiro-OMeTAD)/Au and, in order to reproduce J-V curves with a kink, perovskite carrier mobility has been decreased below 0.25 cm(2) /(V. s) and defect density in the active layer has been increased above 1 x 10(14) cm (3) . For each parameter, J-V curves have been simulated for different AM1.5 irradiation levels, from dark conditions up to 2 suns. For each device, a set of circuital parameters has been obtained independent of irradiation level. The dependence of Mazhari's circuit parameters on both carrier mobility and defect density will be discussed.
