A comparative analysis of opto-thermal figures of merit for high temperature solar thermal absorber coatings

Highly efficient and durable solar thermal energy harvesting via scalable hierarchical coatings inspired by stony corals

“…To calculate the solar or solar-weighted absorptance (SWA, or a SW ) of the coatings, measurements of spectral absorptance a(l) were carried out in the pristine state and after ageing, in the wavelength range of l = [250, 2500] nm. The SWA follows a clear consensus in the literature 16…”

“…These coatings implement an organic binder 15 that decomposes during a curing process to produce a nano-textured porous coating with spinel pigments, without macro-scale (>50 μm) features. Solar absorptance, the key performance metric, 12,16 is typically reported after long-term isothermal exposure at high temperature, with the highest reported values being 94.6% after ageing for 2350 h at 850 °C, 14 97.2% after ageing for 2000 h at 800 °C, 15 and 96.3% after ageing for 3800 h at 770 °C. 13 However, unstable optical performance is generally observed in CST coatings because the elevated temperatures re-arrange the material phases, 17 alter the material composition, 12,13 modify the nano-scale morphology via sintering and crystal grain growth, 18 and may change large-scale morphological features due to the growth of an oxide layer between the coating and metallic substrate, 13 e.g.…”

Potential Electricity Production by Installing Photovoltaic Systems on the Rooftops of Residential Buildings in Jordan: An Approach to Climate Change Mitigation

“…Energy has been crucial to the demographic, social and economic development of human society [1][2][3][4][5]. However, climate change is now one of the world's most pressing environmental issues [6][7][8][9]. As outdoor temperatures rise, building energy demands will also increase [10][11][12].…”

The Effects of Soiling and Frequency of Optimal Cleaning of PV Panels in Palestine

“…that the use of non-renewable energies is detrimental to nature when fossil fuels are burned causing emissions of gases like CO 2 and other harmful gases, which is related to dangerous problems such as global warming and air pollution. Therefore green clean energy like solar energy is an excellent alternative source, especially where it has many advantages, such as no major damaging effects on the environment, it is safe and cheap, and, finally, it is lasting [5][6][7][8].…”
