In this study, Deep Level Transient Spectroscopy (DLTS) measurements have been performed on Cu(In,Ga)Se 2 (CIGS) solar cells from an inline co-evaporation system. The focus of investigation is directed the effect rubidium-fluoride (RbF)-post-deposition treatment (PDT) defects in CIGS absorber layer. Different traps can be identified and their properties are calculated. Herein, different methods...

OPAL2 calculator has proved to be an effective technique for simulating optical losses in various materials applications. This study demonstrates the use of this softwareto simulate transmittance (T) and reflectance (R) hence evaluate properties flash evaporated CuIn1-xGaxSe2(CIGS) thin films with a ratio x = 0.28 deposited on stainless-steel (STS) glass substrates. The simulation results exhib...

Light management strategies are of utmost importance to allow Cu(In,Ga)Se2 (CIGS) technology market expansion, as it would enable a conversion efficiency boost well thinner absorber layers, increasing sustainability and reducing production costs. However, fabrication architecture constraints hamper the direct transfer light architectures from other photovoltaic technologies. The demand for in t...

Abstract A Zn(O, S) thin-film is deposited utilizing an open-air CVD method by evaporating zinc-diethyldithiocarbamate, which a non-vacuum and dry process. In X-ray diffraction measurement, it revealed that the films have wurtzite structure [O]/([O] + [S]) ratio of 10%. bandgap energy 3.1 eV estimated from transmittance reflectance spectra. By applying as n-type buffer layer, Cu(In, Ga)Se 2 sol...

The main thin-film solar cell technologies are evaluated with respect to the criteria Cost, Applicability, Sustainability and Compatibility with the Dutch PV infrastructure. This evaluation concerns the following technologies in particular: thin film crystalline silicon, separated into low and high temperature deposition processes (LT-f-Si, HT-f-Si), amorphous silicon (a-(Si,Ge):H), copper indi...

Cu(In,Ga)Se2 thin films (CIGS) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of Co-evaporated metallic precursors in Se-containing environment under N2 gas flow. Structural properties of prepared thin film were studied. To characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

The performance of a combined solar photovoltaic (PV) and thermoelectric generator (TEG) system is examined using an analytical model for four different types of commercial PVs and a commercial bismuth telluride TEG. The TEG is applied directly on the back of the PV, so that the two devices have the same temperature. The PVs considered are crystalline Si (c-Si), amorphous Si (a-Si), copper indi...

Perovskite-Cu(In,Ga)Se2 (CIGS) thin-film tandem technology provides an exciting prospect to achieve low-cost high-efficiency photovoltaic devices by high throughput roll-to-roll processing on flexible substrates. However, no report perovskite-CIGS mini-modules has been published due scribing-related challenges in realizing near-infrared (NIR)-transparent perovskite Herein, NIR-transparent mini-...
