Unfortunately, the unstable hole transport layer (HTL), limited carrier diffusion length, abundant interface defects, and inferior hole extraction efficiency result in unsatisfactory device performance. Here, we propose a novel Cs₂AgBiBr₆ carbon-based double perovskite solar cell (C-DPSC) without an HTL to enhance device performance. The Cs₂AgBiBr₆ C-DPSC is achieved by optimizing absorber layer thickness, gradient structure (doping gradient, gradient defects, and gradient energy bands), average doping density, and interface defect density through Solar Cell and Capacitance Simulator (SCAPS). The gradient structure in Cs₂AgBiBr₆ C-DPSC exhibit the excellent average defect tolerance density of 10¹⁶ cm⁻³ and enhanced built-in electric field, facilitating the effective separation of photogenerated electron-hole pairs. Moreover, the formed gradient energy bands have a negligible impact on the overall device performance. Compared to the conventional Cs₂AgBiBr₆ PSC with an HTL, which exhibited an open-circuit voltage of 1.09 V, a short-circuit current of 3.80 mA/cm², a fill factor of 40.23 %, and a power conversion efficiency of 1.67 %, the corresponding electrical parameters of Cs₂AgBiBr₆ C-DPSC with an optimized gradient structure was elevated to 1.69 V, 12.11 mA/cm², 88.79 %, and 18.21 %, respectively.

Central Tower Power Generation Plants are made up of hundreds of heliostats that redirect solar radiation to a target. The precision of the solar tracking is affected by a series of cumulative errors generated by the structure, the installation, and the sun tracking system. The present work describes a practical methodology for generating a prediction model to calculate the drift errors of a heliostat. The methodology for predicting annual drift behavior focuses on heliostat deterministic misalignment and installation errors due to the most significant sources of drift error. These sources are the angular reference offset, pedestal tilt, and canting errors. The drift prediction is based on the assumption that the drift curve of a heliostat is the linear sum of the drift curves from these individual errors. This model can be used to predict the drift of a heliostat for any value of solar declination based on only one drift curve performed on any day of the year. The proposed model can provide means for drift prediction affecting each heliostat that can be used to compensate the tracking error. This understanding allows for correct tracking and increases the solar field’s optical efficiency, thereby enhancing the efficiency of a solar tower plant in real-world applications.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"289 ","pages":"Article 113323"},"PeriodicalIF":6.0,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed quantile mapping method is fit on reanalysis data to first bias correct for regional climate models (RCMs) and is tested on RCMs forced by general circulation models (GCMs) to understand existing biases directly from GCMs. Additionally, we adapt a functional analysis of variance methodology that analyzes sources of remaining biases after implementing the proposed quantile mapping method and consider biases by climate region. The proposed method is able to correct for biases due to seasonality on a monthly time scale as well as produce physically plausible values in the corrected data when compared to observed GHI. Analysis shows that biases from GCMs are generally not geographically specific and that RCMs may contribute strong biases to GHI that need to be corrected for.

A novel FPV system with three-point mooring is proposed in this study, and the stability and mooring strength of the novel FPV system is discussed through the numerical simulation and model tests. An anisotropic ice numerical model is developed to simulate the coupled interaction between ice and the FPV structure based on finite element method-cohesive element method (FEM-CEM), and the accuracy of the ice-FPV structure coupled interaction model is verified based on a series of dynamic ice force model tests. Based on the established coupled interaction model, the dynamic ice force variation law of the proposed novel FPV are investigated under different ice velocities and thicknesses, and dynamic behaviors for mooring lines tension forces are quantitatively studied under sea ice in time domain. Meanwhile, structural damage analysis is carried out by comparing stress and strain. It is found that the component connection position on front sides of the FPV structure are areas where the damage occurs first; Afterwards, cracks are generated in connection positions on the rear side, resulting in complete fracture failure.
