Enhanced performance of perovskite solar cells by modulating the Lewis acid-base reaction.

High efficient Perovskite solar cells base on Niobium Doped TiO2 as a Buffer Layer

Here, the effect of lightly Niobium doped TiO2 layer on the performance of perovskite solar cells has been studied by using solar cell capacitance simulator (SCAPS). N addition, the effects of Niobium concentration, buffer film thickness and operating temperature on the performance of the perovskite solar cell are investigated. For doping level of 3.0 mol% into the TiO2 layer, cell efficiency o...

Investigation of the Effect of Band Offset and Mobility of Organic/Inorganic HTM Layers on the Performance of Perovskite Solar Cells

Abstract: Perovskite solar cells have become an attractive subject in the solar energydevice area. During ten years of development, the energy conversion efficiency has beenimproved from 2.2% to more than 22%, and it still has a very good potential for furtherenhancement. In this paper, a numerical model of the perovskite solar cell with thestructure of glass/ FTO/ TiO2/...

بررسی اثر فازی آلومینا بر بلورینگی لایه پروسکایت در سلول‌های خورشید پروسکایتی

Organic-inorganic perovskite (CH3NH3PbI3), due to an appropriate energy gap to absorb sunlight, is used as an absorbent layer in third generation solar cells. Crystallinity of light absorbing layer plays an important role in the performance of perovskite solar cells and substrate plays an important role on crystallinity of light absorbing layer. In superstructure solar cells, alumina (aluminum ...

Nonstoichiometric acid–base reaction as reliable synthetic route to highly stable CH3NH3PbI3 perovskite film

Perovskite solar cells have received worldwide interests due to swiftly improved efficiency but the poor stability of the perovskite component hampers the device fabrication under normal condition. Herein, we develop a reliable nonstoichiometric acid-base reaction route to stable perovskite films by intermediate chemistry and technology. Perovskite thin-film prepared by nonstoichiometric acid-b...
