SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗93 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Energy and exergy analysis of a photovoltaic thermal thermoelectric system integrated with an earth air duct for building applications ↗
Buildings account for a considerable share of global energy consumption, mainly due to heating, cooling, and electricity demands, which highlights the need for efficient renewable energy technologies. Although photovoltaic/thermal–thermoelectric generator (HPVTE) systems and earth–air ducts (EADs) have individually demonstrated promising performance, their integrated application for simultaneous space heating, cooling, and electrification has not yet been comprehensively investigated. To the best of the authors’ knowledge, this study provides the first systematic thermodynamic parametric asses…

Reinforcement learning-based adaptive coordination of solar energy for load, battery, electric vehicle, and hydrogen storage ↗
The intermittency of solar photovoltaic (PV) systems creates critical challenges in real-time energy coordination, multi-energy routing, and long-duration storage management that conventional rule-based controllers fail to resolve under uncertainty. Battery storage capacity limitations necessitate complementary hydrogen storage for long-duration energy resilience, yet no unified framework has effectively coordinated both with PV generation, load demand, and grid interaction in real time. To address these gaps, a hybrid energy-management framework is proposed that integrates PV generation, batt…

DTAC-assisted carbon-modified anatase TiO2 Photoanodes for DSSC-powered photovoltaic–electrochemical hydrogen production ↗
Defect engineering in semiconductor oxides has emerged as a potent strategy for advancing next-generation solar-to‑hydrogen (STH) conversion technology. Herein, we report a novel dodecyl trimethyl ammonium chloride (DTAC)-assisted hydrothermal synthesis of carbon-modified anatase TiO₂ (C-TiO₂) nanoparticles of ∼15.93 nm, wherein DTAC functions concurrently as a carbon source and a morphology-directing agent. The optimized C-TiO₂ (10DTA) demonstrates significant defect development characterized by interstitial carbon incorporation and oxygen vacancy formation, producing a continuum of sub-band-…

Use of helical finned heat sinks to enhance energy efficiency of photovoltaic panels and analysis with deep learning ↗
Increasing operating temperature is one of the main factors limiting the electrical performance of photovoltaic (PV) modules; therefore, effective passive thermal management is important for improving their energy utilization and operational performance. In this study, aluminum helical-finned heat sinks with an 8 mm pitch were integrated into the rear surface of 50 W monocrystalline PV modules in PCM-free and RT42 PCM-filled configurations. Three different numbers of heat sinks (33, 22, and 11) were experimentally investigated under outdoor climatic conditions in Elazığ, Türkiye. Panel tempera…

The increasing deployment of utility-scale photovoltaic (PV) systems necessitates advanced monitoring frameworks capable of providing interpretable operational assessments beyond conventional SCADA visualization and threshold-based supervision. This study proposes a physics-informed analytical digital twin framework for monitoring the operational behavior of a grid-connected PV system using synchronized three-phase electrical measurements. The framework integrates SCADA data acquisition and preprocessing, physics-informed electrical feature engineering, Composite Health Index (CHI) constructio…

Photovoltaic tilt optimization using physics-informed machine learning methods ↗
Photovoltaic arrays are typically installed at a tilt angle, measured from the horizontal plane, close to the site latitude; however, this approach can underperform relative to the physics- or data-driven optimum tilt, resulting in suboptimal energy yields. In this work, we introduce a physics-informed machine learning framework to determine the annual fixed tilt that maximizes energy yield for Antalya, Turkiye. To this end, we process daily irradiance records to derive the diffuse fraction and seasonal harmonics. We use the Liu-Jordan isotropic model to generate a physics-based reference curv…

Dynamic Estimation of Representative Backsheet Temperature for Rooftop Photovoltaic Modules Under Extreme Heat: Thermal Inertia, Temporal Resolution, and Machine Learning ↗
Accurate module-temperature estimation supports assessment of rooftop photovoltaic (PV) systems, but minute-scale meteorological fluctuations and thermal memory challenge steady-state models. This study used 44,638 synchronized one-minute records from a rooftop PV platform in Chongqing, China, during August 2025. The representative backsheet temperature was the arithmetic mean of five simultaneously valid sensors. Physical, static XGBoost, and thermal-history-aware XGBoost models were compared. Lagged values, strictly prior rolling means, and increments were constructed uniformly for four mete…

Uncooled mid-infrared photovoltaic detector based on Pb1−xCdxSe thin films for use in non-dispersive infrared methane gas sensors ↗
Abstract This work is focussed on sputtered lead cadmium selenide (Pb 1−x Cd x Se) thin films as the active material within high-speed room temperature mid-infrared photovoltaic (PV) detectors for use in non-dispersive infrared gas sensors. Variation of the Cd content provides a means of controlling material bandgap and hence wavelength response. Traditional methods of Pb 1−x Cd x Se deposition are thermal evaporation or chemical bath techniques which do not provide required stable deposition for accurate control of Cd content and hence wavelength response. This paper describes pulsed direct c…

Synthesis and performance optimization of an integrated tandem beam splitting module with perovskite solar cells ↗
The global energy transition demands increasingly efficient utilization of renewable energy sources. Solar spectral beam splitting technology, which directs photons of different wavelengths to photovoltaic and photothermal units respectively, offers a promising pathway toward comprehensive solar energy utilization. Perovskite solar cells, with their advantages of low cost, tunable bandgap, and high efficiency in short-wavelength bands, represent ideal photovoltaic components for such systems. This study investigated an integrated small-scale tandem beam splitting module combining thin-film int…

Toward high-efficiency photovoltaic energy harvesting: experimental validation of continuous, hybrid, and sensorless dual-axis tracking systems with fixed-tilt solar system ↗
Solar tracking systems have gained considerable attention due to their potential to increase the energy yield of photovoltaic (PV) systems by maintaining the PV module at a favorable orientation relative to the Sun. However, conventional dual-axis trackers often rely on high-power motors and frequent mechanical actuation, resulting in substantial auxiliary energy consumption and depletion of stored battery energy that could otherwise be conserved for nighttime operation. Moreover, variations in solar position caused by daily and seasonal changes, together with unpredictable weather conditions…

How to assess evidence about Solar
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
