TL;DR: A sequential deposition method for the formation of the perovskite pigment within the porous metal oxide film that greatly increases the reproducibility of their performance and allows the fabrication of solid-state mesoscopic solar cells with unprecedented power conversion efficiencies and high stability.

TL;DR: The use of a solid hole conductor dramatically improved the device stability compared to (CH3NH3)PbI3 -sensitized liquid junction cells.

TL;DR: Using highly sensitive photothermal deflection and photocurrent spectroscopy, the absorption spectrum of CH3NH3PbI3 perovskite thin films at room temperature is measured, finding a high absorption coefficient with particularly sharp onset and a compositional change of the material.

TL;DR: The complex refractive index of planar CH3NH3PbI3 thin films at room temperature is investigated by variable angle spectroscopic ellipsometry and spectrophotometry and results agree well with previously reported data of the absorption coefficient and are consistent with Kramers-Kronig transformations.

TL;DR: In this article, the performance of lead sulfide and cadmium sulfide (CdS) quantum dots (QDs) was investigated in solid-state solar cells with 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spiro-OMeTAD+ cation.
