CuInS2 thin film formation on a Cu tape substrate for photovoltaic applications

Effect of polymer layer deposition and annealing on photovoltaic properties of CuInS2/polymer structures

“…CIS film preparation on a copper tape (CISCuT) by the method of indium electrodeposition, with following sulphurization is described in detail in [8].…”

Electronic Properties of Cu-In-S Solar Cells on Cu-Tape Substrate

“…The final and the longest stage is the annealing of the tape, which takes about 4 s under the atmospheric pressure of the N 2 gas. The fabrication technology of the absorber has been described in more detail by Penndorf et al [2] and it has been recently investigated by Winkler et al [6]. For the present study, we sorted out absorbers which show an asymmetrical diode-like I-V characteristic when contacted by a metal spring contact ("as-grown" cells).…”

“…The major advantages of the CISCuT process are high throughput with sulphurisation/heat treatment time of about 6-7 s, continuous roll-to-roll manufacturing, cheap flexible copper substrate, electrochemically deposited In precursor and, as a consequence, potential low fabrication costs [1,2]. It turned out, that the very short heat treatment time, not achievable with any other contemporary CIS technology, makes it possible to create a spontaneous layered structure (so-called "as grown" cell, in this paper referred to as "absorber") during a single sulphurisation/heat treatment step, with properties suitable for light energy conversion.…”

Applications of Electrochemistry in the Fabrication and Characterization of Thin‐Film Solar Cells

“…Rotating disk electrode experiments show that Cu deposits under mass transfercontrolled conditions on Mo, whereas In deposits under kinetic control at room temperature. There are a few reports on electrodeposition of Cu/In or In/Cu stacks for the realization of CIS semiconductor compounds [83,84] . One technologically interesting report from Penndorf et al .…”

“…One technologically interesting report from Penndorf et al . [83] describes the use of copper tape as both the substrate and source of Cu for the formation of CuInS 2 . Indium was electrodeposited on the copper tape in a roll -to -roll process with remarkably high current densities of 150 -200 mA cm − 2 with the help of thiourea.…”
