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.

Fig5: Current–voltage (J–V) characteristics of perovskite solar cell constructed using the Al/Ca/perovskite/PEDOT:PSS/ITO substrate under a simulated illumination with a light intensity of 100 mW/cm2 (AM1.5G)

Mentions: Figure 5 plots photocurrent J–V curves of the perovskite solar cell obtained under 100 mW/cm2 illumination and the AM1.5G condition. The cell has an active area of 5 × 5 mm2 and no antireflective coating. Table 1 lists the main characteristics of those samples. According to Table 1, the series resistance (Rs) of cell increases when the thickness of the CH3NH3PbI3 perovskite film increases, and the thickness of the CH3NH3PbI3 perovskite film can affect the carrier diffusion length in a device that strongly absorbs light in the red spectral region. The perovskite solar cell fabricated on the 210-nm-thick perovskite film showed the highest power conversion efficiency (EFF), η = 11.99 % value (Jsc = 21.9 mA/cm2) due to increased photocurrent density. From the J–V curve and η value, we can decide that the optimized passivating thickness of the perovskite film is 210 nm thick. However, further increase in thickness of the perovskite film to 220 nm resulted in decrease of η = 9.88 % value (Jsc = 22 mA/cm2). Therefore, a film of optimal thickness would absorb more light and yield a higher current.Fig. 5
