Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu₂ZnSnS₄ Solar Cells Enabling High Efficiency and Stability. [PDF]

Adv Sci (Weinh)
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

Effects of Cd 1-x Zn x S alloy composition and post-deposition air anneal on ultra-thin CdTe solar cells produced by MOCVD [PDF]

Materials Chemistry and Physics, 2017
Ultra-thin CdTe:As/Cd1-xZnxS photovoltaic solar cells with an absorber thickness of 0.5 μm were deposited by metal-organic chemical vapour deposition on indium tin oxide coated boro-aluminosilicate substrates. The Zn precursor concentration was varied to compensate for Zn leaching effects after CdCl2 activation treatment.

Study of ultra-thin CdTe/CdS heterostructure solar cell purveying open-circuit voltage ∼1.2 V

Materials Research Express, 2019
This study focuses on aiming higher stabilized sunlight to electricity conversion efficiency for Cadmium Telluride (CdTe) absorber based solar cell. Common CdTe solar cell with Au back or Zinc Telluride (ZnTe) back surface field (BSF) with Cu back metal has voltages < 1V. The reason behind this low voltage has been investigated in details.

Electrochemical formation of ultrathin Ag/Cd films onto Au(111) substrates

Electrochemistry Communications, 2007
Abstract The formation of an ultrathin bilayer of Ag/Cd in the system Au(1 1 1)/Ag + , Cd 2+ , SO 4 2 - has been studied by conventional electrochemical techniques and in situ scanning tunneling microscopy (STM). Cyclic voltammetric measurements carried out in a solution containing both Ag + and Cd 2+ ions have shown that the ...
