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: Figure 2a, b presents the cross-sectional and surface FESEM images of the perovskite films on glass substrate. Perovskite prepared by the one-step coating method shows cuboid-like crystals, the average CH3NH3PbI3 crystal size from about 200 nm to about 600 nm, as shown in Fig. 2a. A high-resolution image of the cross section of the obtained perovskite solar cell configuration is shown in Fig. 2b. It clearly indicates the presence of each layer of ITO (200 nm), PEDOT:PSS (~50 nm), perovskite (~200 nm), and PCBM (~80 nm).Fig. 2
