Design of Mn-doped CdxZn1-xSe@ZnO triple-shelled hollow microspheres for quantum dots sensitized solar cells with improved photovoltaic performance

The Rise and Future of Discrete Organic–Inorganic Hybrid Nanomaterials

“…Several commonly used methods exist for the formation of shells: Successive ionic layer adsorption and reaction (SILAR), − in which cationic and anionic precursors are added separately to form monolayers one at a time (Figure ). Cation exchange, in which introduced precursor cations exchange with cations within the core QD, causing an inward growth of a shell (Figure ).…”

Poly(3,4‐ethylenedioxythiophene) in Dye‐Sensitized Solar Cells: Toward Solid‐State and Platinum‐Free Photovoltaics

“…Zhang et al prepared the composite PEDOT/MWCNTs by simple and reproducible oxidative electropolymerization method on FTO glass. [261] The studied samples differed for the adopted deposition charge (5,25,100,200, 400 mC cm -2 ). Through SEM analysis, it was noted that MWCNTs-PEDOT showed higher porosity and that the thickness of the film increased with the deposition charge.…”

“…[20][21][22] 2021 will celebrate the 30th anniversary of their invention, [23] which has led to the generation of new knowledge in the field of molecular dyes, semiconductors and electrolytes formulations. [24][25][26][27][28] Their transition at an industrial scale was delayed for many years, and this was mainly due to the desire to consider DSSCs as alternatives to Si-based cells; [29] however, these technologies differ greatly in terms of materials, performance, costs and end-of-life disposal. [30][31][32][33][34] In the last decade, the scientific community has focused the attention on the strengths of DSSCs, namely operation in diffused light conditions, the possibility of creating flexible devices and the tunable aesthetic aspect.…”

High quantum yields generated by a multi-band quantum dot photocell

“…These result in the Shockley-Quiesser detailed balance limit and the energy conversion efficiency is found [12] to be about 33%. Due to their quantum confinement in three dimensions resulting in the tunable size and accordingly tunable band gap, QDs are playing a vital role in the solar cells domain and have achieved a considerable attention in the recent decades [14][15][16][17][18][19]. Not only that, but QDs have the great potential to significantly increase the photo-to-charge efficiency via the formation of IBs in the band gap of the background semiconductor, which can absorb photons with energy below the semiconductor band gap through transitions from the VB to the IB and from the IB to the CB [20][21][22][23][24][25][26][27][28][29].…”
