Photovoltaic solar cells have been extensively used for various applications and are considered one of the most efficient green energy sources. However, their 2D surface area harvesting has limitations, there is an increasing need to explore possibility multiple layer harvest enhanced density. To address this, we developed spectral-selective transparent thin films based on porphyrin iron oxide compounds that allow light penetrate layers, significantly These designed as photovoltaic (PV)...
Heterocyclic, macrocycle organic compounds, structurally characterized with porphyrins, are not only abundant in nature but also environmentally friendly. These porphyrinic compounds have recently been extensively studied for their fascinating structures, physical properties, and high potentials engineering applications. We report experimental results on the photonically activated thermal energy conversion via irradiations of white light (simulated solar light). The photothermal effects well...
Abstract A fundamental challenge in energy sustainability is efficient utilization of solar towards energy‐neutral systems. The current cell technologies have been most widely employed to achieve this goal, but are limited a single‐layer 2D surface. To harvest light more efficiently, multilayer system capable harvesting cuboid through transparent photothermal thin films iron oxide and porphyrin compound developed. Analogous capacitor, an array transparent, spectral selective, allows white...
In contrast to a conventional single layer solar still, herein multilayer system for light harvesting and water evaporation via transparent photothermal thin films is developed. Monodispersed Fe 3 O 4 @Cu 2– x S nanoparticles are dispersed in polymer solution deposited on glass quartz substrates as films. These optically characterized with strong absorptions the UV NIR regions, high average visible transmittance. The photon energies UV/NIR regions converted heat increasing rate, while film...
The temperature dependency of photovoltaic power conversion efficiency (PCE) has been a key challenge to solar applications due intrinsic processes. Herein, an alternative strategy is developed by modulating the light spectrum with series photonic hybrids. Transparent thin films are synthesized solutions porphyrin compounds and iron oxides which exhibit strong absorptions in UV IR regions. These spectral photonically tuned via compositional optimization absorb photons near 400 nm above 1127...
Spectral-selectively solar harvest is achieved in designated frequency regions for photothermal energy generation. In this study, we have designed and synthesized porphyrin-based hybrids that typically exhibit two absorption peaks respectively near 400 nm (blue-violet) 700 (NIR). To be able to tune the optical absorptions more efficient especially IR region, unique porphyrin are developed by incorporating another compound such as phthalocyanine, inorganic Fe 3 O 4 @Cu 2-x S nanoparticles...
The US highway system features a huge flux of energy transportation in terms weight, speed, volume, flow density, and noise levels, with accompanying environmental effects. adverse effects high-volume traffic cause health concerns for nearby residential areas. Both chronic acute exposure to PM 2.5 have detrimental on respiratory cardiovascular health, motor vehicles contribute 25–35% direct emissions. In addition traffic-related pollutants, residing near major roadways is also associated...
