Perovskites: transforming photovoltaics, a mini-review

Abstract

Abstract. The recent power-packed advent of perovskite solar cells is transforming photovoltaics (PV) with their superior efficiencies, ease of fabrication, and cost. This perovskite solar cell further boasts of many unexplored features that can further enhance its PV properties and lead to it being branded as a successful commercial product. This article provides a detailed insight of the organometal halide based perovskite structure, its unique stoichiometric design, and its underlying principles for PV applications. The compatibility of various PV layers and its fabrication methods is also discussed.

Polarization-selective three-photon absorption and subsequent photoluminescence inCsPbBr3single crystal at room temperature

“…9 In particular, the hybrid perovskites CH 3 NH 3 PbX 3 (MAPbX 3 ) have been extensively studied as potential PV materials, and MAPbX 3 -based PV cells have shown remarkable PCEs up to ∼ 20%. [8][9][10][11][12] While the actual device architecture is a critical factor in terms of technology evolution, the basic understanding of essential light-matter interaction in these perovskite materials is unarguably important for increasing the PCE as well as discovering other emerging optoelectronic properties such as radiation detection, 13 thermoelectricity, 14 lasing, 15 and light-emitting diodes.…”

Pathways toward high-performance perovskite solar cells: review of recent advances in organo-metal halide perovskites for photovoltaic applications

“…27 The pace of progress has been remarkable and unprecedented in PV history and can likely be attributed to several factors related to inexpensive fabrication costs, ease of processing, and the excellent optoelectronic properties of the materials. 7,9,[10][11][12][13] As will be described in Sec. 3, high-quality perovskite thin films can be fabricated using a variety of processes including solution- 26,28 and vapor-based [29][30][31] deposition methods.…”

“…Recent research suggests that organometal halide perovskites (OMHPs), with methylammonium lead iodide (CH 3 NH 3 PbI 3 or MAPbI 3 ) being the prototypical example, have the potential to meet these conditions and become competitive in the marketplace. As a result of intensive research efforts across the globe over the past three years, [4][5][6][7][8][9][10][11][12][13] perovskite-based solar cell PCEs are now comparable to or better than most other PV technologies, and the simple device processing promises lower manufacturing costs, suggesting the potential to challenge the prevailing silicon technology in the foreseeable future. 14 The term perovskite refers to the crystal structure of calcium titanate (CaTiO 3 ), which was discovered by the German mineralogist Gustav Rose in 1839 and named in honor of the Russian mineralogist Lev Perovski.…”

Large diffusion lengths of excitons in perovskite and TiO2 heterojunction

“…However, as it was shown in Ref. 7 , an ordinary excitonic picture does not explain the existence of the large electron-hole diffusion lengths in perovskite semiconductors [4][5][6] at room temperature. The main reason is that an estimate electron-hole coupling energy (2meV ), based on electrooptical properties of a perovskite solar cell, is small compared to the room thermal energy (kT ∼ 26meV ) (see also 8 ).…”

“…Exceptional performance of > 15 percent power conversion efficiency 2,3 is associated with the efficient light absorption and large electron-hole diffusion lengths 4,5 (for a recent review see 6 ). However, as it was shown in Ref.…”
