Integrating Hyperuniform Disordered Light Trapping Layers in Ultrathin c-Si Solar Cells ↗
Abstract Ultrathin crystalline silicon solar cells require advanced light trapping to compensate for weak near-infrared (NIR) absorption. Here, we integrate hyperuniform disordered light-engineered (HUDLE) nanopatterns with high-quality surface passivation in 4.8 μm c Si cells and demonstrate robust device operation enabled by broadband coupling to guided modes. HUDLE layers enhance the fraction of power scattered beyond the escape cone by up to 30% in the NIR and increase average external quantum efficiency (EQE) by >50% over flat cells and 10% over periodic designs from 750 to 1000 nm. We di…

Solar-Assisted IoT waste monitoring system with photovoltaic energy feasibility assessment ↗
Internet of Things (IoT)-based waste monitoring systems are increasingly used to support smart and efficient waste management systems. However, many existing systems still depend on conventional batteries or grid power, which can increase maintenance requirements and limit outdoor deployment. Although solar photovoltaic (PV) energy can support low-power IoT systems, the practical feasibility of PV supply for smart waste-monitoring nodes is often not evaluated quantitatively. This paper presents a solar-assisted IoT waste-monitoring system and assesses the feasibility of photovoltaic energy. Th…

Numerical study of hydrodynamics and power performance of offshore floating photovoltaic: Effects of connector failure ↗
As a core component of the offshore floating photovoltaic (OFPV) system, connectors exert a decisive influence on the stable operation of the entire multi-float structure. In this study, a coupled hydrodynamic-solar power generation model for the OFPV system is developed. First, a hydrodynamic model of a hinged dual-hexagonal OFPV system is built using the open-source DualSPHysics code, and the model is validated against available physical experimental data. Subsequently, a dynamic photovoltaic power generation model is constructed based on the pitch motion of the floats. Failure cases were si…

Design and numerical analysis of antimony trisulfide (Sb 2 S 3 ) solar cell using SCAPS-1D software ↗
Abstract Abstract This study numerically analyzes an Sb₂S₃ based solar cell with the structure FTO/ETL/Sb₂S₃/SpiroOMeTAD/Au using the SCAPS1D software under the AM1.5G spectrum.The impact of series resistance (Rs), defect density and the effective capture cross-section of charge carriers at the Sb₂S₃/CdS interface were first studied. Alternative electron transport layers (ETLs) including Cd1-xZnₓS, ZnO1-xSx, and TiO₂, were then investigated. The results indicate that optimal band alignment at the ETL/Sb2S3 interface is achieved for a sulfur content of 0.6 in ZnO1-xSx and a zinc contents of 0.5…

Short-Circuit Current Analytical Method for Photovoltaic Systems Considering Dual Closed-Loop Control Dynamic Characteristics ↗
Accurate short-circuit current calculation is crucial for protection coordination and grid integration of large-scale photovoltaic (PV) plants, yet conventional methods often lack transient accuracy. Based on field tests under varying power and voltage-dip conditions, this study proposes an analytical short-circuit current calculation method for PV systems considering the dynamic characteristics of dual closed-loop control. The complete fault transient process is divided into distinct stages according to control mode switching and limiter actions. The method incorporates stage-wise active powe…

Impact of climate change on the photovoltaic power potential in Sweden across 21st century ↗
Abstract Solar photovoltaic generation strongly relies on weather conditions, which will be affected by future climate change. Traditional methods for estimating photovoltaic generation potential often overlook detailed installation factors and snow impacts, leading to inaccuracies in high-latitude areas. We assess future photovoltaic system performance in Sweden using a validated photovoltaic installation model that incorporates air temperature, radiation and snow conditions. Applying this model to four Swedish cities under low- and high-emission climate change scenarios and three climate sim…

In Situ Supramolecular Depolymerization Enables Bifunctional Buried‐Interface Passivation in Inverted Perovskite Solar Cells ↗
ABSTRACT Introducing multidentate organic passivators has emerged as an effective strategy for defect passivation at the buried interface of inverted perovskite solar cells (PSCs). However, the active polar functional groups within these passivators are prone to supramolecular polymerization, which compromises passivation effectiveness. Herein, a supramolecular depolymerization strategy synergistically driven by thermal annealing and heteromolecular interactions is proposed. This approach enables the in situ depolymerization of the Zaltoprofen (Za) supramolecular structures introduced at the b…

Achieving Energy Efficiency in Building Heating and Cooling by Optimising Solar Energy-Based Control ↗
This paper examines the optimisation of control for a building heating and cooling system integrated with solar energy and a heat pump under the climatic conditions of Fergana Region. Solar irradiance G(t), outdoor air temperature T_a (t) and wind speed v_w (t) were included directly in the model as external disturbances. The model combines building thermal dynamics and wind dependence with electricity generation by the photovoltaic (PV) system and temperature-dependent heating and cooling models for the heat pump. The control problem was formulated as a model predictive control (MPC) method u…

Thermal management of photovoltaic panels using perforated Acp plates under outdoor conditions ↗
Abstract The operating temperature of photovoltaic (PV) modules is a key factor affecting electrical output because heat accumulation reduces voltage, power generation, and conversion efficiency. This study experimentally evaluated a passive thermal-management method using perforated aluminium composite panel (ACP) plates installed on the rear side of a 100 Wp polycrystalline PV module under outdoor conditions. Three perforation diameters, 20, 22.5, and 25 mm, were compared with an uncooled reference panel. Solar irradiance, PV surface temperature, lower-panel/ACP-plate temperature, voltage, c…

Spectrally selective structures for glass cover of silicon photovoltaic module to enhance its energy yield based on neural network surrogate-assisted genetic algorithm ↗
Strategically transmitting harvestable photons and reflecting non-useful photons are essential for photovoltaic (PV) efficiency improvement and temperature reduction. However, it remains a considerable challenge to develop spectrally selective thin-film structures that can maximize PV lifetime energy yield (EY) while maintaining structural simplicity and adequate manufacturability. Herein, a neural network surrogate-assisted genetic algorithm (NNSGA) framework is proposed to facilitate the design of spectrally selective structures. By incorporating spectral utilization weight (SUW) of PV modul…

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.
