| Abstract |
| Perovskite solar cells (PSCs), which have numerous advantages of low cost,
optimum band gap and efficiencies at par with Si solar cells, might become the
next generation photovoltaic (PV) technology. Several studies suggest Bi2FeCrO6
(BFCO) could be a prospective lead free and stable absorber material for PSC. In
this study, a multilayer PSC using BFCO as the perovskite absorber is designed
and modelled. The PV performance of a double perovskite BFCO under different
hole transport layers (HTLs) like MoO3
, Cu2O, P3HT, NiO, CuSCN, Spiro-Ometad,
PEDOT:PSS and NPB is numerically analyzed using SETFOS 5.3 software. To improve
the power conversion efficiency (PCE), the impact of several properties, such as
thickness, doping and defect concentration of the absorber layer and the charge
transport layer, is carefully optimized. Furthermore, the external quantum
efficiency of BFCO PSC is investigated, including recombination efficiency, series
and shunt resistance, and the examination of many bottom electrodes to assess
their influence on device performance. PEDOT:PSS showed the best performance
among all HTLs for the BFCO solar cell. The device structure FTO/NSTO/Bi2FeCrO6
/
PEDOT:PSS/Au displayed the highest PCE of 23.14% with 1.262 V of open circuit
voltage, 82.21% of fill factor and 22.30 mA/cm2
of short circuit current. |
