Earlier sources: Solar
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 ↗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.

Adaptive search-space reduction and partial shading detection for high-efficiency MPPT in photovoltaic systems ↗
Abstract This paper proposes an integrated maximum power point tracking (MPPT) framework for photovoltaic systems operating under uniform and partial shading conditions. The framework incorporates a partial shading detection technique (PSDT) that simultaneously identifies the operating condition and adaptively reduces the search space by eliminating regions that cannot contain the global maximum power point (GMPP) and avoiding redundant sampling, thereby accelerating the subsequent MPPT process. Based on the identified condition, an enhanced divide-and-conquer algorithm with ternary ratio (EDC…

Numerical simulation and performance optimization of InPbI3 perovskite solar cells ↗
In this study, InPbI 3 -based perovskite solar cells were numerically analyzed using the SCAPS-1D simulation tool. The device architecture, FTO/WS 2 /InPbI 3 /CuI, was modeled and systematically optimized. The investigation focused on the influence of parameters such as the thicknesses of the hole transport layer (HTL), electron transport layer (ETL), and absorber layer, as well as the acceptor dopant concentration in the perovskite, donor dopant concentration in the ETL, interface defect densities, series and shunt resistances, operating temperature, and metal work function on device performa…

Numerical analysis and Investigation of the compatibility of kesterite hole transport layers with MASnI3 perovskite solar cells ↗
This study focuses on the design, performance optimization, and comparative analysis of MASnI 3 -based solar cells with various quaternary kesterite hole transport layers (HTLs). The influence of key parameters, such as absorber thickness, acceptor concentration, defect density, interface defect density, as well as transport layer thickness and carrier concentration, on device performance was systematically optimized using SCAPS-1D simulation software. Furthermore, the study also investigates the effect of operating temperature within the 300–500 K range, series resistance, and shunt resistanc…

Impedance Spectroscopy Approach for a 2T Perovskite/Silicon Tandem Solar Cell ↗
Impedance spectroscopy (IS) is a powerful tool for analyzing the physical mechanisms occurring in single-junction solar cells. However, identifying the impedance responses of the top and bottom sub-cells within a tandem solar cell remains challenging. This is because the series connection of the two sub-cells results in an overall tandem impedance in which the contributions of the individual sub-cells are combined and may even overlap, making their individual impedance contributions difficult to distinguish and investigate. This work proposes a diagnostic approach for monolithic perovskite/sil…

From Pixel Receptive Fields to Ground Spans: GSD-Conditioned Cross-Resolution Feature Alignment for Photovoltaic Detection and Segmentation ↗
Photovoltaic (PV) inventories with explicit location and extent are needed for energy accounting, distribution-grid planning, and asset monitoring. However, the ground sampling distance (GSD) of different sources spans nearly an order of magnitude, so a sampling window of fixed pixel size covers 64 times more ground at 0.8 m than at 0.1 m. This physical-scale discrepancy can weaken cross-resolution generalization. To address this, this paper proposes CRFA-PVNet, a physically guided cross-resolution feature alignment network for PV detection and segmentation, which describes the receptive field…

Research on the Impact and Optimization of the Active Current Recovery Rate of Distributed Photovoltaic Pulse Blocking Strategy on Grid Frequency and Voltage Stability ↗
With the large-scale integration of Class B distributed photovoltaic power sources without fault-tolerant capabilities, the “pulse blocking-recovery” transient behavior during power grid faults has become a key factor affecting the frequency and voltage stability of the system. The recovery rate of active current after pulse blocking directly determines the speed of filling the active power deficit, but the mechanism of its impact on frequency and voltage stability has not been fully revealed. This paper first establishes a frequency response model for photovoltaic power grids with high penetr…

Toward wind-resilient cable-supported photovoltaic system: nonlinear stiffness, dynamic identification, and parametric instability ↗
Cable-supported flexible photovoltaic (FPV) system is emerging as lightweight low-carbon power-generation structures, but their large-span, low-stiffness configuration makes them susceptible to large-amplitude wind-induced oscillations, for which the conventional small-amplitude assumption no longer provides a valid basis for dynamic analysis. This study establishes a finite-amplitude nonlinear dynamic framework for two-cable FPV systems, in which vibration-induced cable-force evolution is explicitly incorporated into the governing equations as time-varying stiffness. Based on this framework,…

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.
