摘要：

Despite the recent unprecedented increase in the power conversion efficiencies (PCEs) of small-area devices (<= 0.1 cm(2)), the PCEs deteriorate drastically for PSCs of larger areas because of the incomplete film coverage caused by the dewetting of the hydrophilic perovskite precursor solutions on the hydrophobic organic charge-transport layers (CTLs). Here, an innovative method of fabricating scalable PSCs on all types of organic CTLs is reported. By introducing an amphiphilic conjugated polyelectrolyte as an interfacial compatibilizer, fabricating uniform perovskite films on large-area substrates (18.4 cm(2)) and PSCs with the total active area of 6 cm(2) (1 cm(2) x 6 unit cells) via a single-turn solution process is successfully demonstrated. All of the unit cells exhibit highly uniform PCEs of 16.1 +/- 0.9% (best PCE of 17%), which is the highest value for printable PSCs with a total active area larger than 1 cm(2).
