This energy thread follows solar through original research, public projects, and source reports. Read the evidence below to see which developments are represented in SYMTRI’s archive.
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 ↗91 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.

State Transport Routing for Short-horizon Adaptation in Multi-horizon Photovoltaic Forecasting ↗
Recent power measurements provide valuable information for photovoltaic(PV) power forecasting, but directly extrapolating short-term trends can introduce substantial errors over longer forecast horizons. To address this challenge, we propose state transport routing (STR), a lightweight adapter that refines the predictions of a frozen forecasting model. STR combines the original forecast with two complementary trajectories derived from the latest measured power level and its recent trend. A horizon-conditioned router adjusts their contributions over the first 120 min, while leaving subsequent p…

Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu 2 ZnSnS 4 Solar Cells ↗
ABSTRACT Wide‐bandgap kesterite Cu 2 ZnSnS 4 (CZTS) is a promising top‐cell candidate for tandem photovoltaics owing to its earth‐abundant composition and low‐cost solution processability. However, its progress is hindered by a large open‐circuit voltage ( V OC ) deficit. A key origin lies in the defects generated during sulfurization. For solution‐processed CZTS absorbers, an intermediate‐phase pathway involving Cu 2 SnS 3 and other intermediate phases alters the local chemical environment and crystallization behavior, leading to substantial defects and carrier recombination. Here, we develop…

Fluorination-Dependent Phosphonic Acid Additives for Enhanced Perovskite Film Quality, Stability, and Photovoltaic Performance in Inverted Solar Cells ↗
Defect passivation is essential for suppressing non-radiative recombination and improving the stability of perovskite solar cells. In this work, we examine how the degree of fluorination in benzylphosphonic acid additives affects film quality and device performance. Two fluorinated analogs are compared, and 2,3,4,5,6-pentafluorobenzylphosphonic acid (pFBPA) is found to adsorb preferentially at iodine vacancy sites through stable Pb-O coordination, as confirmed by binding energy analysis. This passivation effect produces better film morphology, more favorable energy level alignment, and improve…

Efficiency Enhancement of Organic Solar Cell Via Incorporation of Ag NPs and Moth-Eye-like Structure ↗
Abstract This study investigated a simple strategy for enhancing the efficiency of organic solar cells (OSCs) by incorporating silver nanoparticles (Ag NPs) and an antireflection moth-eye (ARM) film. The device structure was composed of a commercially available ARM film/indium tin oxide-coated glass substrate/aluminum-doped zinc oxide (AZO):Ag NPs/poly(3-hexylthiophene-2,5-diyl) (P3HT): [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM)/MoO3/Ag. The use of a commercially available ARM film eliminated the complexity of the nanofabrication processes, enabling a simple and practical device fabri…

Experimental study on thermal management and water harvesting characteristics of integrated solar panel with wet air adsorption ↗
• A low-cost and highly hygroscopic lithium bromide solution is adopted to construct an integrated solar system. • Photovoltaic waste heat drives water desorption while simultaneously enabling photovoltaic cooling. • The integrated system provides an efficient solar-driven approach for synergistic water and energy production. • The water collection efficiency of the system reached a peak of 46.7 g m −2 h −1 . Cooling the photovoltaic (PV) panels via wet air adsorption–desorption is attracting increasingly attentions due to its passive operation and cooling efficiency. However, the cooling dura…

Tailoring flexible Cu₂SnS₃ thin film solar cells through controlled heating rate and sulfurization time ↗
Cu₂SnS₃ (CTS) thin films were fabricated on flexible Mo foil substrates using a two-stage process consisting of spin coating of precursor films followed by sulfurization in a Rapid Thermal Processing (RTP) system at 525 °C. The effects of heating rate and sulfurization time on the structural, morphological, optical, electrical, and photovoltaic properties of the CTS films were systematically investigated. X-ray diffraction and Raman spectroscopy confirmed that all films predominantly crystallized in the monoclinic CTS phase, accompanied by minor tetragonal CTS and trace Cu₂Sn₃S₇ secondary phas…

Devitrification of solar panel glass waste with fly ash for use as a partial cement replacement in concrete ↗
The rapid expansion of solar energy deployment is expected to generate substantial volumes of end-of-life solar panel waste, creating an increasing need for effective recycling and valorization strategies. This study compares the performance of solar panel glass waste (SPGW) and solar panel glass waste devitrified with fly ash (d-SPGW) in cement paste and concrete mixtures. SPGW and d‐SPGW were incorporated at replacement levels of 12.5 wt% (SPGW12.5/d-SPGW12.5) and 25 wt% (SPGW25/d-SPGW25). Cement paste samples were used for setting time and hydration-temperature measurements, mercury intrusi…

Thermo-economic analysis of a wire-mesh integrated photovoltaic thermal collector ↗
This study experimentally compared a flat-plate photovoltaic-thermal air collector with and without a double-crimped galvanized iron wire mesh. Both units were tested together for eight days under identical outdoor conditions in Noida, India at an optimized airflow rate of 0.0165 kg/s. The hourly and daily means, along with standard deviations and 95% confidence intervals, were calculated; statistical significance tests were carried out; and a sensitivity analysis was performed to confirm the robustness of the mesh-integrated PVT system over the conventional PVT system. The mesh-integrated sys…

Semantic Surface Integration in CityJSON-Based Urban Digital Twins: A Rooftop Photovoltaic Potential Use Case ↗
Urban digital twins provide an integrated framework for combining semantic 3D city models, simulation results, and interactive visualization in support of urban energy analyses. While existing approaches effectively represent results at the building scale, extending this capability to individual semantic surfaces remains challenging. Applications such as rooftop solar assessment require simulation results to be associated with each roof surface and visualized at the same level of detail, yet current CityJSON visualization tools do not support attribute-driven rendering of surfaces belonging to…

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.
