Abstract:

Fabrication and characterization of CH₃NH₃PbI₃ perovskite solar cells using silicon phthalocyanine (SiPc) with decaphenylcyclopentasilane (DPPS) were performed. 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 stabilities of conversion efficiency were maintained for 28 days. The photovoltaic performance depended on the (100) crystal orientation and the crystallite size. Photovoltaic properties were also obtained without using spiro-OMeTAD as a hole transport layer.
