The microcavity perovskite solar 2014 dodge ram 1500 fender flares cells (PSCs) are designed by sandwiching the perovskite layer between the ultrathin Ag and opaque Ag electrodes.Compared to transparent-conductive-oxide (TCO) based PSCs, the microcavity PSCs with the bare Ag electrode show the poor optical performance due to the transmittance limit of Ag film.By introducing an optical coupling layer, the remarkably improved transmittance of the Ag electrode and enhanced light absorption in the perovskite layer are obtained.

Furthermore, the better light absorption is available by adopting an optical spacer, and the resulted microcavity PSCs achieve the comparable or even higher JSC than TCO-based PSCs.This provides a southwestern aztec rug guideline to design and fabricate efficient TCO-free PSCs.
