Accelerating Electron‐Transfer and Tuning Product Selectivity Through Surficial Vacancy Engineering on CZTS/CdS for Photoelectrochemical CO2 Reduction

“…[ 22 ] However, due to serious carrier recombination, pristine CZTS actually exhibits poor PEC activity. [ 23 ] Various strategies have been applied to alleviate the recombination in pristine CZTS, such as p ‐ n junction construction [ 24 ] and cation substitution. [ 25 ] For example, Wong et al.…”

Revealing the electronic structure, heterojunction band offset and alignment of Cu2ZnGeSe4: a combined experimental and computational study towards photovoltaic applications

“…12,13 In addition to these issues, the kesterite based photovoltaic devices suffer from severe band tailing, which particularly reduces the open circuit voltage (V oc ) of solar cells. 14 Rey et al reported the origin of band-tails in kesterite materials and showed that the large band tailing causes voltage losses that limit the efficiency of kesterite-based devices. 3,15 However, there have been recent efforts of using single or double cation substitution strategies to control band tailing in CZTS.…”

“…17 Lie et al also observed that the incorporation of Mg in Cu 2 ZnSnS 4 to form Cu 2 Mg x Zn 1Àx SnS 4 (varying x from 0.0 to 1.0) could suppress these defects and improve the open circuit voltage. 14 Recently, Dhawale et al reported an improvement in the V oc -deficit mainly due to the reduced band tailing obtained by controlling the Ge/(Sn + Se) ratio. 18 Nagaya et al reported the advantages of Ge in CZTS, 19 with a very small tail state formed in CZGSe compared to the large band tailing observed in CZTS and CZTSe.…”

Carbon Transition‐metal Oxide Electrodes: Understanding the Role of Surface Engineering for High Energy Density Supercapacitors

“…In addition, other synthesis methods such as microwave-assisted, plasma-assisted synthesis and spray pyrolysis can offer easier procedure and faster reaction kinetics compared to other solution-based methods; thus, they are usually used to increase the production yield. [36][37][38] These techniques are alternative methods for the preparation of high-performance C-TMO hybrids. Notably, the combination of two or more synthetic methods are often employed to support the complex interaction between the surface oxygen functionality of TMO and the carbon network, including heteroatoms such as O, N and S, in which the carbon material anchors the TMO covalently through the formation of MÀ O-C/N/S bond.…”
