Fabrication and Characterization of Perovskite Solar Cells Using Silicon Phthalocyanine Complex

: CH 3 NH 3 PbI 3 perovskite solar cells using silicon phthalocyanine (SiPc) with decaphenylcyclopentasilane (DPPS) were fabricated and characterized. Effects of hole transport capacity of SiPc on the photovoltaic properties were investigated by changing the concentration of the SiPc. Continuous addition of SiPc and DPPS on the perovskite layer improved the short circuit current density related to the conversion efficiency. The conversion efficiencies were stable for 28 days. The photovoltaic performance depended on the (100) crystal orientation and the crystallite sizes.
