Abstract

The highly efficient CH₃NH₃PbI₃ perovskite solar cell (PeSC) is simply achieved by employing a blended electron-transport layer (ETL) consisting of PC₆₁BM and P(NDI2OD-T2). The high molecular weight of P(NDI2OD-T2) allows for a thinned ETL with a uniform morphology that optimizes the PC₆₁BM ETL more effectively. As a result of this enhancement, the power conversion efficiency of a PC₆₁BM:P(NDI2OD-T2)-based PeSC is 25% greater than that of the conventional PC₆₁BM based-PeSC; additionally, the incorporation of P(NDI2OD-T2) into PC₆₁BM attenuates the dependence of the PeSC on the ETL-processing conditions regarding its performance. It is revealed that, in addition to the desirable n-type semiconducting characteristics of PC₆₁BM:P(NDI2OD-T2)-including a higher electron-mobility and a more-effective electron selectivity of a blended ETL for an efficient electron extraction-the superior performance of a PC₆₁BM:P(NDI2OD-T2) device is the result of a thinned and uniformly covered ETL on the perovskite layer.
