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 ↗88 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.

A descriptor-driven framework for SiNx:H in crystalline silicon solar cells: linking bonding configuration to device performance and reliability ↗
Hydrogenated silicon nitride (SiN x :H) is a cornerstone material in crystalline silicon photovoltaics, simultaneously providing antireflection functionality and defect passivation. However, these roles are typically treated independently, limiting predictive optimization, particularly in advanced architectures such as TOPCon, bifacial, and silicon-based tandem solar cells. This review synthesizes the literature on plasma-enhanced chemical vapor deposited (PECVD) SiN x :H into a descriptor-driven framework that unifies deposition conditions, bonding configuration, material descriptors, and dev…

AIoT-Enabled Edge Intelligence Framework for Real-Time Monitoring and Fault Diagnosis in Photovoltaic Systems Through LSTM and Random Forest ↗
The reliable operation of photovoltaic (PV) systems requires effective methods for distinguishing anomalies from normal environmental variations. This study presents an Artificial Intelligence of Things (AIoT) framework for real-time PV monitoring and anomaly diagnosis. The proposed system integrates custom data acquisition, MQTT communication, edge computing, an LSTM Autoencoder, and Random Forest classification. Experimental validation was conducted under real operating conditions at three scales: a 500 W microinverter-based system, a 3.9 kWp grid-connected installation, and a 62.5 kWp PV su…

Optimal Photovoltaic Integration for Offsetting Temperature-Dependent Auxiliary Electricity Demand in an Air-Cooled Geothermal Power Plant ↗
Air-cooled binary geothermal power plants experience increased auxiliary demand and reduced net output during hot operating periods. This study develops a grid-connected photovoltaic (PV) sizing framework for an operating approximately 25 MW plant in the Menderes Massif, Türkiye. A measured 8760 h plant-wide auxiliary-load series, calculated from the plant’s 2025 SCADA gross and net electrical-output records, was used directly as the demand input in MATLAB (R2026a) and HOMER Pro (version 3.18.4). NASA POWER provided hourly ambient-temperature and solar-irradiance data. MATLAB performed hourly…

Molecular Coordination–Driven Photothermally Stable FACs‐based Perovskite Solar Cells with Efficiency Over 25% via Dicarbonyl‐Functionalized Thienoacene Small Molecule ↗
ABSTRACT The practical deployment of perovskite solar cells (PSCs) is critically hindered by their susceptibility to moisture, oxygen, and thermal degradation, particularly under high‐temperature and high‐humidity conditions. Herein, we design and synthesize a dicarbonyl‐functionalized thienoacene passivator featuring multiple Lewis basic sites and medium‐length heptyl chains. This molecule exhibits exceptional thermal stability and anchors robustly at perovskite grain boundaries via multidentate Pb─O and Pb─S coordination bonds, effectively relieving interfacial tensile strain, passivating el…

MFPN-ASPP: MobileNet feature pyramid with ASPP for photovoltaic panel defect segmentation ↗
Abstract Photovoltaic (PV) fault detection through thermal infrared imaging is a crucial step for efficient operation and maintenance of large-scale solar plants. Although current deep learning methodologies demonstrate potential, their efficacy is limited by inadequate feature extraction on various scales. This research presents an enhanced semantic segmentation model that combines a feature pyramid network (FPN) with a lightweight MobileNetV2 backbone and an atrous spatial pyramid pooling (ASPP) module. The model is trained, evaluated, and tested on the Photovoltaic Thermal Images dataset. T…

Ultraviolet irradiation-induced improvement of silicon heterojunction solar cells via zinc-doped indium oxide with low ultraviolet transmittance ↗
The application of silicon heterojunction (HJT) solar cells in space environments faces a critical challenge from ultraviolet-induced degradation (UVID). In this work, high-quality zinc doped indium oxide (IZO) films with narrow bandgap were prepared by reactive plasma deposition (RPD). UV irradiation can cause the breakage of some Zn-O bonds, facilitating the formation of oxygen vacancies. This enhances the electrical conductivity of IZO and reduces work function, thereby improving energy level alignment with the n-type doped layer and promoting electron transport. HJT solar cells with IZO ex…

Engineering efficient RbGeCl3 perovskite solar cells: A simulation-driven computational approach to performance optimization ↗
The development of lead-free perovskite solar cells (PSCs) is critical for advancing environmentally sustainable photovoltaic technologies. This study systematically evaluates the photovoltaic potential of RbGeCl 3 as a lead-free absorber using SCAPS-1D simulations. Unlike studies, this work goes beyond limited configurations or single-layer studies by delivering multi-parameter optimization and comparative ETL engineering of RbGeCl 3 PSCs for high-performance lead-free devices. An initial screening of 48 device configurations with varied electron transport layers (ETLs) and hole transport lay…

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression ↗
ABSTRACT Phosphor‐sensitized organic solar cells (PS‐OSCs) enhance exciton utilization and suppress non‐radiative recombination by incorporating triplet‐enabled sensitizers into bulk‐heterojunction blends. Here, we report a green‐emitting Ir‐3 complex as a multifunctional phosphor‐sensitizer in ternary OSCs based on PM6, two newly designed pyrazine‐derived donor polymers, PBDT‐Pyz (N1) and PBDT‐T‐Pyz (N2), and the non‐fullerene acceptor L8‐BO. N1 and N2 exhibit deep HOMO levels (−5.59/−3.63 eV and −5.58/−3.60 eV) and planar backbones for efficient charge transport, while Ir‐3 (E g opt = 2.50 e…

Insights from Autoresearch for Solar Panel Segmentation ↗
This paper investigates AutoResearch, a protocol in which a coding language model edits a training program under a one-hour GPU budget and retains a change only if validation IoU improves. The protocol is applied to photovoltaic panel segmentation on a frozen real-image split, with DeepLabV3--ResNet-50 held fixed. Three campaigns of 24 experiments, using Gemma~4 12B, Qwen3-8B all improve their one-hour baselines, but retained modifications do not transfer across hardware. The Qwen3-8B configuration, trained on real images only, reaches a test IoU of 0.836 versus 0.833 for the reference GAN-aug…

Innovative Charge-Selective Contacts for Simplified Crystalline Silicon Heterojunction Solar Cells ↗
This study investigates the implementation of dopant-free charge-selective contacts—i.e., the replacement of conventional doped hydrogenated amorphous silicon (a-Si:H) layers—for silicon heterojunction (SHJ) solar cells as a simplified alternative to conventional architectures. Although standard in the industry, doped a-Si:H layers induce significant parasitic absorption and require complex PECVD processing. By utilizing wide-bandgap transition metal oxides and alkali metal salts, this approach is expected to reduce optical losses, potentially offering a route toward simplified device architec…

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.
