“…These show the positive impact that made by Southeast Asia countries. Thus, besides Malaysia, other Southeast Asia countries also have done researches on CIGS thin-film solar cells, such as Thailand and Vietnam as can be seen in Tables 9 and 10, respectively [140][141][142][143].…”

This study gives a selective overview of the technological status and comparison of selected thin-film solar cells. In the first part of this study, the development of thin-film solar cells is assessed, followed by comparison of the design structure among those thin-film solar cells and the current status of thin-film solar cells efficiency. The advantages and disadvantages of thin-film solar cells are also discussed. In the second part of this study, a comprehensive review is done on research upon copper-indium-gallium-diselenide (CIGS) thin-film solar cell in Southeast Asia countries. As compared with other regions of the world, Southeast Asia has not started the large manufacturing of CIGS yet, however, the research on it has been started.

“…[3] Numerous examples consisting of Al 2 O 3 , ZnO, SiO 2 or enameled layer, deposited by sputtering, sol-gel, PECVD or spray techniques have been previously investigated. [10][11][12][13][14] Nevertheless, few of them report on the electrical properties of these layers and the effect of surface roughness on the dielectric function.…”

Thin-film PV modules grown on flexible, light weight, thermally stable and low cost substrates such as stainless steel foil, are an attractive product for solar market applications. When metal foils are used as substrate, it is essential to deposit a dielectric barrier layer to isolate electrically and chemically the thin-film solar cells front the substrate. In this work, SiOx stacks deposited on 'rough' stainless steel by a combination of a new sol-gel formulation and a Plasma Enhanced Chemical Vapor Deposition (PECVD) deposition step are reported as a suitable dielectric barrier layer candidate. Using these SiOx multilayers, a smooth and homogeneous film was achieved. X-ray diffraction (XRD) analysis showed that back contact of the solar cell (based on Molybdenum) is not affected by the presence of the barrier layer. Moreover, according to X-ray photoelectron spectroscopy (XPS) and Secondary Ion Mass Spectrometry (SIMS) measurements, this approach led to excellent barrier layer properties against the diffusion of impurities from the stainless steel. A complete electrical characterization of these dielectric barrier layers was also carried out showing good electrical insulation. GRAPHICAL ABSTRACT RESEARCH HIGHLIGHTS -Dielectric barrier layer for flexible metallic substrates has been developed. -SiO x based on Sol-Gel process showed a novel chemical formulation. -The dielectric barrier layer exhibits a dielectric breakdown voltage about 1000 V for a 4 microns thick stack. -Dielectric barrier layer was capable to reduce the surface roughness by 40-50%. -This research opens new challenges for low cost thin-film manufacturing.

“…Despite of that, Mo deposition also presents certain problems related to bad substrate adhesion and fast metal oxidation . The back contacts used for high‐efficiency devices are typically deposited by direct current (dc) sputtering, evaporation, or chemical vapor deposition (CVD) that increase the final value of the cell.…”

7In this work, we investigated the properties of silver and gold enamels as potential back 8 contacts for Cu(In,Ga)Se2 (CIGS) solar cells. The enamels were deposited on ceramic 9 tiles by non-vacuum printing techniques. Thus, we are proposing a development of 10 integrated photovoltaic tile for the first time. We also explained the CIGS synthesis 11 procedure using co-precipitation of selenites precursors. To deposit the precursor 12 powders on the substrate, a doctor blade method is applied. The interface morphology 13 between ceramic tile, back contact, and CIGS absorber was studied as a critical factor 14 for the final solar cell performance. The thermal treatment effect on the back contact 15 properties was also reported. 16Excellent compatibility between CIGS and gold layer was observed, keeping thickness absorber were obtained when silver enamels were used.
