Bottom Line: The performance of the organic solar cells was observed by changing the thickness of CH3NH3PbI3 perovskite.The thickness of a perovskite film can affect the carrier diffusion length in a device that strongly absorbs light in the red spectral region.The short-circuit current density and the power conversion efficiency were 21.9 mA/cm(2) and 11.99 %, respectively, for the sample with 210-nm-thick CH3NH3PbI3 perovskite active layer.

ABSTRACT

Unlabelled: This work presents a CH3NH3PbI3/PCBM organic solar cell. Organic PCBM film and CH3NH3PbI3 perovskite film are deposited on the

Pedot: PSS/ITO glass substrate by the spin coating method. The performance of the organic solar cells was observed by changing the thickness of CH3NH3PbI3 perovskite. The thickness of a perovskite film can affect the carrier diffusion length in a device that strongly absorbs light in the red spectral region. The short-circuit current density and the power conversion efficiency were 21.9 mA/cm(2) and 11.99 %, respectively, for the sample with 210-nm-thick CH3NH3PbI3 perovskite active layer.

Mentions: In this study, a PEDOT:PSS (CLEVIOS Al 4083) film was spin-coated on a pre-cleaned ITO substrate at 5000 rpm for 30 s. After spin coating, the film was annealed at 140 °C for 10 min. The perovskite layer was deposited by the solvent-engineering technology of 1.2 M PbI2 and 1.2 M methylammonium iodide (MAI) in a cosolvent of dimethyl sulfoxide (DMSO) and γ-butyrolactone (GBL) (vol. ratio = 1:1) in a glove box filled with highly pure nitrogen. The perovskite solutions were then coated onto the PEDOT:PSS/ITO substrate by two consecutive spin coating steps, at 1000 and 5000 rpm for 10 and 20 s, respectively. At 5000 rpm for 20 s, the wet spinning film was quenched by dropping 50 μl of anhydrous toluene. After spin coating, the film was annealed at 100 °C for 10 min. A solution of PCBM was spin-coated on the perovskite layer/PEDOT:PSS/ITO substrate at 3000 rpm for 30 s. Finally, a Ca/Al electrode was completed by thermal deposition with a thickness of 100 nm. Figure 1 schematically depicts the complete structure. The roles of the PCBM film, CH3NH3PbI3 film, and PEDOT:PSS film in the cell structure is electron transport layer, active layer, and hole transport layer, respectively.Fig. 1
