Figure 4: 2D/3D Mesoporous Solar cell characteristics and stability.
From: One-Year stable perovskite solar cells by 2D/3D interface engineering
(a) Device cartoon of the Hole transporting Material (HTM)-free solar cell and of the standard HTM-based solar cell. (b) Current density voltage (J–V) curve using the 2D/3D perovskite with 3% HOOC(CH2)4NH3I, AVAI hereafter, in a standard mesoporous configuration using 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD)/Au (devise statistics and picture of the cell in the inset). (c) Stability curve of the Spiro-OMeTAD/Au cell comparing standard 3D with the mixed 2D/3D perovskite at maximum power point under AM 1.5G illumination, argon atmosphere and stabilized temperature of 45 °C. Solid line represent the linear fit. In the inset the champion device parameters are listed.
