Vacuum-free laminated top electrode with conductive tapes for scalable manufacturing of efficient perovskite solar cells

0.1016/j.nanoen.2 lsevier Ltd. All rig thor. [email protected] ( Abstract The efficiency of organometal trihalide perovskites (OTP) solar cells have reached that parity of single crystal silicon, and its nature abundant raw material and solution-process capability promise a bright future for commercialization. However, the vacuum based techniques for metal electrode deposition and additional encapsulation layer increase the cost of the perovskite solar cells dramatically and impede their commercialization process. Here, we report a vacuum-free low temperature lamination technique to fabricate the top electrode by commercial conductive tapes (Ctape). The simple fabrication method yields good quality contact and high efficiency device of 12.7%. The C-tapes also encapsulated the devices effectively, resulting in greatly improved device stability. The combination of lamination of electrodes and encapsulation layers into a single step significantly reduce the cost of device fabrication. & 2015 Elsevier Ltd. All rights reserved.
