Abstract
- Fabrication and characterization of methylammonium lead iodide perovskite solar cells incorporated with methylammonium bromide (MABr), formamidinium bromide (FABr), and decaphenylcyclopentasilane (DPPS) were performed. Additive effect of MABr or FABr into the perovskite layers inserted with DPPS as hole-transporting layer was investigated. Addition of 5% MABr or FABr into the perovskite layer improved the short-circuit current density, shunt resistance, and open-circuit voltages, which depended on the uniform morphologies while suppressing defects and pinholes in the perovskite layer. The stabilities of the photovoltaic performance depended on the degree of incorporation of MABr or FABr with the DPPS layer, which suppressed decomposition in the perovskite layer.
