Hysteresis and transient behavior in current–voltage measurements of hybrid-perovskite absorber solar cells

Abstract

This report discusses slow transient and hysteretic phenomena in perovskite-absorber solar cells.

Ultrasmooth organic–inorganic perovskite thin-film formation and crystallization for efficient planar heterojunction solar cells

“…7b the J-V curve for the best device fabricated from the PbAc 2 route measured under simulated AM 1.5G (100 mW cm À 2 ) solar irradiation in air, exhibiting outstanding 3% when scanned from SC to FB, so far among the highest efficiencies based on CH 3 NH 3 PbI 3 with a PHJ structure 5,7,10,26 . The hysteresis between forward and backward J-V scan is a manifestation of a slow response time of the cell to a change in load and the mechanism, although yet to be fully understood, is discussed in detail in recent publications 35,36 . The best means to compare cells that exhibit hysteresis is to measure the 'stabilized power output' under load near the maximum power point.…”

Efficient and Air‐Stable Mixed‐Cation Lead Mixed‐Halide Perovskite Solar Cells with n‐Doped Organic Electron Extraction Layers

“…Both the perovskite absorber layer and the interfaces between the perovskite and the charge extraction layers can have a significant impact upon the long-term stability of the solar cell. [11][12][13][14][15][16] All commercial solar modules are encapsulated in order to enable 25 years of operation. Silicon modules have historically been encapsulated with a polymer back sheet laminated with a hot-melt polymer foil to a glass front sheet, and are moving toward glass-glass laminates to deliver improved stability.…”

Optoelectronic Studies of Methylammonium Lead Iodide Perovskite Solar Cells with Mesoporous TiO2: Separation of Electronic and Chemical Charge Storage, Understanding Two Recombination Lifetimes, and the Evolution of Band Offsets during J–V Hysteresis

“…Several authors have reported on this effect and speculated about the causes. [18][19][20][21][22] Some recent articles present cell designs that minimize this hysteresis. 23,24 In this article, we describe the hysteresis effect in additional detail.…”

“…18 All three of these possibilities remain in the debate. 5,19,20,20,25 Along with the addition of crystal size effects 21 . It has been proposed that an optimum mesoporous TiO 2 film thickness minimizes the JV hysteresis.…”
