Recent progress in organic–inorganic halide perovskite solar cells: mechanisms and material design

Abstract

While energy shortage is always an issue, the impending exhaustion of fossil fuel sources makes it an ever increasingly pressing one.

Beneficial Effects of PbI2 Incorporated in Organo‐Lead Halide Perovskite Solar Cells

“…[ 1 ] The performance of cells using the perovskite materials [2][3][4][5][6][7][8] has already surpassed that of both conventional dye-sensitized and organic photovoltaics as well as inorganic nanoparticle (including quantum dots)-based solar cells. [9][10][11][12][13][14] This mainly stems from the easy band gap tuning by managing the chemical composition, [ 5,7 ] large optical absorption, high carrier mobility, and very long electron-hole diffusion lengths.…”

Photodecomposition and Morphology Evolution of Organometal Halide Perovskite Solar Cells

“…However, exploration of device stability and degradation of the materials has been less studied 12 compared to research on device engineering [13][14] and device physics. [15][16][17][18][19] Nevertheless, the importance of stability is widely recognized, 12 and several studies have examined the stability of perovskite solar cells in humid air using a variety of conditions and device structures. [20][21][22][23][24] For instance, Yang et al found that the identity of the hole transport layer has a dramatic effect on the degradation of triiodide perovskite films using in situ UV-vis measurements, with 2,2',7,7'-tetrakis-(N,N-di-4-methoxyphenylamino)-9,9'-spirobifluorene (Spiro-OMeTAD) and poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA) causing more rapid degradation than poly(3-hexylthiophene-2,5-diyl) (P3HT).…”

Influence of the Synthetic Procedures on the Structural and Optical Properties of Mixed-Halide (Br, I) Perovskite Films

“…[7][8][9][10][11][12] In the case of MAPbI3. and MAPbI3-xClx halide perovskites, the possible relations existing between perovskite properties and processes followed to prepare the material were mainly devoted to features such as morphology and light absorption efficiency, 13,14 since bandgap energy and crystal structure are nearly independent of the preparation procedures (e.g.…”
