The impact of Fe3O4 on the performance of ultrathin Ti/AlN/Ti tandem coating on stainless-steel for solar selective absorber application

Textured Stainless Steel as a Platform for Black Mg2Si/Si Heterojunction Solar Cells with Advanced Photovoltaic Performance

“…Moreover, after optimization of sonication time and concentration of Piranha solution, this procedure was found to provide an AVR of 11%, that was slightly worse than compared with the value achieved for HF-etched SS samples (see Figure 2 b). Additionally, Fe 3 O 4 covering could be applied to suppress impurity diffusion from SS304 [ 13 , 40 ] into the upper Si and silicide light-absorbing layers, as will be demonstrated below.…”

“…Currently, SS is used as a part of complex layered substrates for amorphous and crystalline SCs because of its merits, such as good flexibility, high thermal and chemical stability, low-cost and good electric conductivity. To adopt rolled (or high-gloss) SS substrates for PV demands, the steel industry offers the deposition of intermediate layers for simultaneous surface smoothing, back electrode insulating, and preventing diffusion of various impurities from the SS substrate into the light absorbing layer of thin-film solar cells (TFSCs) for each semiconducting material [ 12 , 13 , 14 ]. Other applications of SS in the PV industry, except for ancillary components, frames, fasteners and connectors, include substrates for solar spectral selective absorbing coatings used in thermo-solar systems [ 15 , 16 , 17 ].…”

Improvement of optical properties of AISI 304 as a solar absorber using a pulsed fiber laser

“…The quality of the solar selective absorber layer also controls achieve high solar absorptance (a s ) and low thermal emittance (3 t ) in order to obtain the best conversion efficiency. 3 There are many ways to obtain spectrally selective solar absorbers by surface modication, such as surface texturing, 4 creating surface roughness, 5 intrinsic structure or nanostructure formation, 6 cermet coating 7,8 and multilayer absorber coating. 9 The creation of an oxide layer as an intrinsic structure and surface roughness is quite simple and produces good conditions for high solar absorptance and low thermal emittance.…”

Li2CO3-doped Dark Calcium Carbonate Pellets for Direct Solar Energy Capture and Fast Heat Storage

“…The CaCO 3 /CaO energy storage cycle system is shown in Fig How to effectively capture solar radiation energy is an important issue in the CaCO 3 /CaO energy storage cycle system. In conventional solar receivers, solar energy is usually absorbed by a surface coating and then radiated to the reactants through the surface coating [12][13][14][15]. This indirect way of absorbing solar energy has huge drawbacks, such as severe heat loss caused by coating radiation and large thermal resistance between pellets and coating.…”
