(A) Device structures of the 2T PVSK/Si tandem solar cell (reproduced from ref. 19, copyright 2017, Nature Energy). (B) Detailed optical loss analysis of ST-PSCs in NIR (800–1,200 nm). ITO layer thickness is set at 140 nm (reproduced from ref. 20, copyright 2018, Elsevier). (C) Schematic of the monolithic PVSK/Si tandem cells (reproduced from ref. 10, copyright 2016, ACS). (D) Absorption spectra and tauc plots of ~10 nm-thick evaporated MoOx, WOx, and V2Ox layers on glass (reproduced from ref. 21, copyright 2016, ACS). (E) Illustrative schematic of the device architecture showing the ITO electrode encapsulation layer (reproduced from ref. 22, copyright 2016, Wiley VCH).
