Here, core\/shell ZnO\/TiO2 NWs with AgCl-doped CdSe quantum dots were fabricated as an electron transport layer (ETL) for perovskite solar cells, based on ZnO\/TiO2 arrays. We designed CdSe with AgCl dopants that were synthesized by a colloidal process. An improvement of the recombination barrier (Rct1), due to shell supplementation with AgCl-doped CdSe quantum dots, improved the open circuit voltage, the fill factor, and the adsorption capacity of CH3NH3PbI3 perovskite with NWs. The enhanced cell steady state was attributable to TiO2 with AgCl-doped CdSe QD supplementation. A maximum power conversion efficiency of 15.12% was attained in an atmospheric environment. The mechanism of the recombination and electron transport in the perovskite solar cells becoming the basis of ZnO\/TiO2 core\/shell arrays was investigated to represent the merit of ZnO\/TiO2 core\/shell arrays as an electron transport layer in effective devices. These results showed an uncomplicated approach for restraining non-radiative recombination loss in hetero-structure core\/shell arrays to significantly improve perovskite solar cell performance and increase the effectiveness of photovoltaics.<\/jats:p>","DOI":"10.3390\/molecules25173969","type":"journal-article","created":{"date-parts":[[2020,8,31]],"date-time":"2020-08-31T08:11:19Z","timestamp":1598861479000},"page":"3969","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["High-Performance Core\/Shell of ZnO\/TiO2 Nanowire with AgCl-Doped CdSe Quantum Dots Arrays as Electron Transport Layer for Perovskite Solar Cells"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-6107-5091","authenticated-orcid":false,"given":"Jin Mo","family":"Kim","sequence":"first","affiliation":[{"name":"Micro LED Research Center, Korea Photonics Technology Institute, Gwangju 61007, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bong Soo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Energy Systems Engineering, Chung Ang University, Seoul 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Won","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of System Semiconductor Engineering, Sangmyung University, 31 Sangmyung dae-gil, Cheonan 31066, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"646","DOI":"10.3390\/coatings5040646","article-title":"Fabrication and Characterization of a Perovskite-Type Solar Cell with a Substrate Size of 70 mm","volume":"5","author":"Oku","year":"2015","journal-title":"Coatings"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"897","DOI":"10.1038\/nmat4014","article-title":"Solvent engineering for high-performance inorganic\u2013organic hybrid perovskite solar cells","volume":"13","author":"Jeon","year":"2014","journal-title":"Nat.
