Prediction of Global Solar Radiation in India Using Artificial Neural Network

open access: yesJournal of Sustainable Development of Energy, Water and Environment Systems, 2016
Increasing global warming and decreasing fossil fuel reserves has necessitated the use of renewable energy resources like solar energy in India. To maximize return on a solar farm, it had to be set up at a place with high solar radiation.

Asymmetric Lamellar Templating of the Perovskite/C60 Interface for Scalable Inverted Perovskite Photovoltaics

open access: yesAdvanced Materials, EarlyView.
Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...

Annual models of monthly mean hourly direct, diffuse, and global solar radiation at ground

open access: yesMeteorologische Zeitschrift, 1999
A method is proposed for estimating monthly mean hourly direct, diffuse, and global solar radiation from annual stochastical models (correlation coefficients are higher than 0.99), using only actual and daily maximum solar elevation and respective daily ...

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

open access: yesAdvanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Bridging Horizontal to Vertical Radiative Cooling. [PDF]

open access: yesAdv Sci (Weinh)
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

open access: yesAdvanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Optimizing solar UV-radiation exposures for vitamin D3: comparing global and diffuse spectral UV radiation

open access: yes, 2008
Currently, there is a major gap in the knowledge that is needed in order to optimise the beneficial effects related to ultraviolet (UV) radiation for vitamin D3 synthesis (UVD3) compared to reducing the biologically damaging overexposure to UV radiation.

Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

open access: yesAdvanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies
