Light Emission Properties of Thermally Evaporated CH3NH3PbBr3 Perovskite from Nano- to Macro-Scale: Role of Free and Localized Excitons

Abstract: Over the past decade, interest about metal halide perovskites has rapidly increased, as they can find wide application in optoelectronic devices. Nevertheless, although thermal evaporation is crucial for the development and engineering of such devices based on multilayer structures, the optical properties of thermally deposited perovskite layers (spontaneous and amplified spontaneous emission) have been poorly investigated. This paper is a study from a nano- to micro- and macro-scale about the role of light-em… Show more

“…At the same time, in spite of the excellent power conversion efficiencies [4][5][6], the technology still requires further improvement through reduction in costs, facilitation of the manufacturing steps and minimization of the environmental pollution associated with the production process [7][8][9]. In recent years, perovskite solar cells (PSC) based on organometallic lead halides have emerged as strong competitors to silicon in the photovoltaic market [10][11][12], as well as an efficient technology to complement the silicon photovoltaic devices in tandem architecture [13][14][15]. These materials boast high efficiency (about 25%) at a fraction of the silicon device thickness, as well as ease of fabrication, making them highly promising for future photovoltaic applications [16][17][18][19][20][21][22].…”
