In this letter, we propose a new PSC with SrTiO3/TiO2 composite MPL to overcome this lower JSC problem. The PSC with the SrTiO3/TiO2 composite MPL generated a comparable JSC (19.3 mA/cm2) to that with the TiO2-MPL, with keeping higher VOC, which resulted in relatively high power conversion efficiency of 9.98%.}, pages = {111--113}, title = {SrTiO3/TiO2 composite electron transport layer for perovskite solar cells}, volume = {187}, year = {2017} }
