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 ↗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.

Stochastic Convex Optimization for Day-Ahead Shared Battery Storage Scheduling in Solar Energy Communities ↗
Energy communities represent a transformative paradigm for decentralized renewable energy integration, enabling collective investment in photovoltaic (PV) systems and battery energy storage systems (BESS) to achieve economic and environmental benefits. However, the optimal operation of these communities faces significant challenges due to inherent uncertainties in solar generation, load consumption, and electricity prices. This paper presents a stochastic optimization framework for day-ahead scheduling of shared battery energy storage in solar-powered energy communities under multiple uncertai…

Hybrid Global Maximum Power Point Tracking for Partially Shaded Photovoltaic Arrays Using Improved Cuckoo Search and Synergetic Control ↗
Partial shading creates multiple peaks in the power–voltage characteristic of a photovoltaic (PV) array, making global maximum power point tracking (MPPT) difficult. This study investigates ICS-Synergetic Control, an event-triggered global–local MPPT framework for a series-connected PV array and Boost converter, in which an improved cuckoo search evaluates candidate peak regions, synergetic control regulates the accepted operating point, and a locking mechanism limits unnecessary perturbations. Two sensing configurations are considered: ICS-SC-I uses module-level irradiance, whereas ICS-SC-E u…

Counter‐Halide‐Directed Ion‐Pair Passivation Enables High‐Performance Wide‐Bandgap Perovskites for Perovskite/Cu(in,Ga)Se 2 Tandem Solar Cells ↗
ABSTRACT Wide‐bandgap (WBG) perovskites (PVSK) are key top‐cell absorbers for tandem photovoltaics but remain limited by severe open‐circuit voltage ( V OC ) losses and photoinduced halide segregation. Since iodide‐ and bromide‐related defects coexist at the surface and bulk of Br/I mixed‐halide WBG PVSK, the counter‐halide identity in ammonium passivators may critically influence defect passivation effectiveness. Moreover, while deprotonation of ammonium passivator has emerged as an important factor governing interfacial stability, its discussion has focused mainly on organic cation structure…

Multi-Objective Optimization of a Photovoltaic–Hydrogen Integrated Energy System for Residential Communities ↗
To achieve low-carbon and low-cost energy supply while meeting the dynamic electricity, heating, and cooling demands of residential communities, an integrated energy system combining solar energy and hydrogen energy is proposed. The start-up characteristics of electrolyzers are incorporated into the system model. With key equipment capacities selected as decision variables, a four-objective optimization framework integrating the non-dominated sorting genetic algorithm II with an elitist strategy and the technique for order preference by similarity to an ideal solution is established to optimiz…

Rooftop photovoltaic potential in data-scarce regions using open-source geospatial information: Scenario-based approach for a Mediterranean coastal city ↗
Rooftop photovoltaic (PV) systems can support urban decarbonization, yet data scarcity limits city-scale assessments in developing regions. This study develops an open-source 2D GIS workflow for five central districts of Antalya, Turkiye, using Overture Maps building footprints. A three-stage procedure combined spatial and size filters, geometry and land-use screening, and targeted image inspection to retain the continuous urban building stock while excluding rural settlements, greenhouses, and structures smaller than 60 m 2 . Planimetric agreement was evaluated against 60 manually delineated…

Screen‐Printed Electrically Isolated Buried Contacts for Metal‐Halide Perovskite/Silicon Tandem Solar Cells: Proof of Concept Devices and Electrical Loss Simulations Highlighting Large‐Scale Potential ↗
Processes for applying front metallization to metal‐halide‐perovskite (MHP)/Si tandem solar cells must carefully account for the intrinsic stability challenges of MHPs—particularly their susceptibility to thermal degradation. The paper presents a proof‐of‐concept for a novel interconnection design for MHP/Si tandem solar cells, named electrically isolated buried contacts (EIBC). This innovative approach involves screen‐printing contacts onto a screen‐printed isolating solder resist layer on the Si bottom solar cell before the MHP top solar cell is fabricated. This method allows the contacts to…

Synergistic defect passivation and crystallization control via bifunctional ethylenethiourea additive in CsPbIBr2 perovskite solar cells ↗
All-inorganic CsPbIBr 2 perovskite is a promising light-harvesting material due to its greater thermal stability compared to organic–inorganic hybrid perovskites. However, low film quality, high defect density, and poor crystallization hinder charge transport and cause non-radiative recombination in CsPbIBr 2 -based perovskite solar cells (PSCs). In this work, ethylenethiourea (ETU), a bifunctional Lewis-base S–donor additive, was introduced to synergistically regulate crystallization kinetics and passivate uncoordinated Pb 2+ defects in CsPbIBr 2 films. The optimized carbon-based PSC incorpor…

Optimal short-term scheduling of a hybrid pumped storage system coupled with photovoltaic under reservoir-plan guidance ↗
Hybrid pumped storage (HPS) plants can leverage existing cascade reservoirs to provide pumped-storage operation, thereby reducing the need for new reservoirs and lowering capital costs; consequently, they are increasingly viewed as a promising alternative to conventional pumped storage. However, while this configuration improves PV integration and enhances system flexibility, it also poses new challenges for coordinating multi-energy dispatch and managing cascade-reservoir regulation. This study selects the first two reservoirs/plants in the middle reaches of the Yalong River as the case syste…

Outdoor performance of photovoltaic mini-modules with aesthetic front glass designs on a south-facing vertical façade in summer ↗
Aesthetic front glass improves architectural appearance while partially concealing the solar cells. Such glazings are usually evaluated under standard test conditions (STC), and information on their outdoor electrical behaviour remains limited. Four photovoltaic mini-modules with identical cells, encapsulation and rear construction were fabricated, differing only in the front glass: an antireflection-coated transparent reference, a gray polysilazane-coated glass, and two ceramic-printed glasses of identical pattern and 25% printed coverage differing only in pigment colour. The modules were ope…

Grid-connected solar photovoltaic-supported dynamic voltage restoration for enhanced voltage stability and power quality ↗
Grid-connected PV systems are important in modern power systems as they enhance voltage stability, improve power quality (PQ), and support renewable energy integration under varying solar generation conditions. However, optimizing voltage restorers remains challenging due to reactive power compensation requirements, system stability issues during PV variations, and diverse grid conditions and load profiles. To overcome this problem, this work proposes a grid-connected solar photovoltaic fed quasi-impedance source driven dynamic voltage restorer employing optimized switching strategy for enhanc…

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.
