Abstract
The performance of solar cells is determined by three factors: the open-circuit voltage (VOC), short-circuit current density (JSC), and fill factor (FF). The VOC and FF are determined by the material bandgap and the series/shunt resistance, respectively. However, JSC is determined by the amount of incident light in addition to the bandgap of the material. In this study, a moth-eye pattern was formed on a glass surface via direct printing to increase the amount of incident light and thus increase JSC. The moth-eye pattern is a typical antireflection pattern that reduces the reflection by gradually increasing the refractive index. A flat perovskite solar cell (F-PSC) and a moth-eye patterned perovskite solar cell (M-PSC) had JSC values of 23.70 and 25.50 mA/cm2, respectively. The power-conversion efficiencies of the F-PSC and M-PSC were 19.81% and 21.77%, respectively. [Figure not available: see fulltext.].
