Quintuple‐Shelled SnO₂ Hollow Microspheres with Superior Light Scattering for High‐Performance Dye‐Sensitized Solar Cells

Abstract

Quintuple-shelled SnO2 hollow microspheres are prepared by a hard-template method. DSSCs constructed with SnO2 multi-shell photoanodes show a record photoconversion efficiency of 7.18% due to enhanced light scattering. SnO2 hollow microspheres that are utilized as a scattering layer on top of P25 films increase the DSSC photoconversion efficiency from 7.29% to 9.53%.

Insight into the liquid state of organo-lead halide perovskites and their new roles in dye-sensitized solar cells

“…Dye-sensitized solar cells (DSCs) were chosen for this test because of the relatively facile fabrication process and comparatively good understanding of their working mechanisms. [11][12][13][14] DSCs based on iodine electrolyte have been fully researched, and the redox mediators of I -/I 3 -have been identified as being responsible for the regeneration of dye. 15 Because of the iodide containing nature of the lead halide perovskite, it would be quite interesting to investigate how such perovskite behaves as an electrolyte in DSCs.…”

Formation of nickel cobalt sulfide ball-in-ball hollow spheres with enhanced electrochemical pseudocapacitive properties

“…Recently, extensive research efforts have been devoted to design and fabricate complex hollow structures with multi-shelled architecture and tunable chemical composition, which are expected to realize their optimized physical/chemical properties for specific applications. Until now, many types of metal oxides with multi-shelled structures have been successfully fabricated based on soft-or hard-template methods [20][21][22][23][24][25] . For example, Lou et al 26,27 have previously fabricated double-shelled SnO 2 hollow spheres using silica spheres as templates combining with designed procedures.…”
