Figure 4. Device performances depending on the condition of perovskite photoactive layer.

Figure 4

Color of line and symbol are as in Fig. 3. (a) External quantum efficiency (EQE). (b) J-V plots (All data were measured at AM 1.5 G with an intensity of 100 mW·cm−2.). Perovskite solar cell characteristics are summarized as follows: perovskite, MAPbI3, with PbI2 [Jsc = 20.4 mA·cm−2, Voc = 0.97 V, FF = 0.66, PCE = 13.0%]; pure perovskite, MAPbI3, without PbI2 [Jsc = 22.0 mA·cm−2, Voc = 0.99 V, FF = 0.69, PCE = 15.0%]; pure perovskite, (MA)x(FA)1−xPbI3, without PbI2, [Jsc = 23.9 mA·cm−2, Voc = 0.99 V, FF = 0.66, PCE = 15.6%]. As for pure MAPbI3 and (MA)x(FA)1−xPbI3 without PbI2, 10 mg·ml−1 of MAI solution and 8 + 2 mg·ml−1 of MAI + FAI mixed solution were utilized for printing process, respectively.
