Figure 5 .

Photocurrent density-voltage curve of the (CH3CH2NH3)PbI3-sensitized solar cell under AM 1.5 G one-sun light intensity. The 2 H perovskite-type (CH3CH2NH3)PbI3-sensitized TiO2 layer was heated at 100°C for 15 min. The active area and TiO2 film thickness were 0.323 cm2 and 5.4 μm, respectively. The inset shows the IPCE spectrum.
