A high recombination rate and thermal budget for aluminum (Al) back surface field are found in the industrial p-type silicon solar cells. Direct metallization on lightly doped silicon, however, exhibits a large Schottky barrier holes because of Fermi-level pinning effect. As result, low-temperature-deposited, dopant-free chromium trioxide (CrO x, x < 3) with stability performance is first applied cell as hole-selective contact at rear surface. By using 4 nm CrO between Ag, we achieve...
A novel electron-deficient quinoid–azaisoindigo building block was synthesized for a series of alternative D–A conjugated polymers, applied as the channel layer in n-type OECTs, achieving mix conducting figure merit μC * 0.53 F V −1 cm s .
ABSTRACT Aims Pollination plays a fundamental role in structuring the reproductive strategies and related traits of host plants. Active pollination is only observed nursery mutualistic systems. However, mechanisms underlying their maintenance are unclear. We aimed to explore factors shaping its global distribution pattern Ficus species specifically putting forward three questions: (1) actively‐pollinated more concentrated areas with older floras? (2) Is active better represented higher...
Abstract Most crystalline silicon (c‐Si) solar cells are based on high temperature–processed p‐n junctions or highly doped heterojunctions. The concept of dopant‐free carrier selective contact has become a research hotspot and been successfully demonstrated with n‐type Si wafers, showing the great potential simplified fabrication process lower thermal‐consuming. However, there few successful cases p‐Si, p‐Si/CdS (cadmium sulfide)/ITO (indium tin oxide) champion efficiency 12.29% (device area...
Simulating land use/cover change (LUCC) caused by urbanization is always one of the most important aspects in city's sustainable development. Previous research mainly simulated urban growth ignoring periodical characteristics cycle, which cannot well meet needs optimizing relationship between urban, agriculture and ecological space. We developed a framework to explore stable pattern terminal stage including following parts: bottom-up conversion probability was estimated from inertial driving...
The development of dopant-free carrier-selective layer demonstrates the potential to overcome parasitic absorption and doping-related recombination caused by heavy doping realize both low current density (J0c) contact resistance (ρc) in simplified procedures. In this work, thermally evaporated yttrium fluoride (YF3) films were demonstrated as electron-selective material for c-Si solar cells. YF3 interlayers have a work function 3.1 eV, allowing lowest ρc 17.8 mΩ·cm2 n-Si/YF3/Al contacts....
In this paper, the explicit equation of single diode model (SDM) expressed by Lambert W function was reduced to its simplified form through variable replacement; then combined with an intelligent optimization algorithm estimate SDM parameters solar cells and PV modules. To evaluate parameter extraction performance new method, eight typical algorithms were implicit, explicit, extract a cell three types The results show that method not only improves accuracy but also enhances robustness...
Dopant-free carrier-selective contacts are becoming increasingly attractive for application in silicon solar cells because of the depositions their fabrication being simpler and occurring at lower temperatures. However, these limited by poor thermal environmental stability. In this contribution, use conductive high work function cuprous iodide, with its characteristic ambient stability, has enabled a hole-selective contact p-type large conduction band offset small valence CuI/p-Si interface....
Abstract Developing ecological approaches for disease control is critical future sustainable aquaculture development. White spot syndrome (WSS), caused by white virus (WSSV), the most severe in cultured shrimp production. Culturing specific pathogen-free (SPF) broodstock an effective and widely used strategy controlling WSS. However, small-scale farmers, who predominate developing countries, cannot cultivate SPF shrimp, as they do not have required infrastructure skills. Thus, these...

In this paper, single-diode model (SDM) and double-diode (DDM) parameters of the French RTC solar cell Photowatt PWP 201 photovoltaic (PV) module were extracted by combining five metaheuristic algorithms with three simulation current calculation methods (i.e., approximation method, Lambert W method Newton–Raphson method), respectively. It was found that parameter-extraction accuracies (LW) (NR) are always approximately equal higher than method. The best RMSEs (root mean square error)...
One of the challenges in fabricating high‐performance n‐type crystalline silicon (n‐type c‐Si) solar cells is high‐quality c‐Si/metal contact. Schottky barriers are commonly found on contact, which suppresses electron transportation. Herein, novel stacks magnesium acetylacetonate (Mg(Acac) 2 )/magnesium (Mg)/silver (Ag) to form electron‐selective contacts for c‐Si presented, enables a dopant‐free process. An ohmic contact formed using Mg(Acac) /Mg/Ag stacks. The transmission spectrum and...
The theoretical rational design of organic semiconductors faces an obstacle in that the performance depends very much on their stacking and local morphology (for example, phase domains), which involves numerous molecules. Simulation becomes computationally expensive as intermolecular electronic couplings have to be calculated from density functional theory. Therefore, developing fast accurate methods for coupling estimation is essential. In this work, by a series new 3D descriptors, we...

Artificial Intelligence (AI) has achieved state-of-the-art performance in medical imaging. However, most algorithms focused exclusively on improving the accuracy of classification while neglecting major challenges a real-world application. The opacity prevents users from knowing when might fail. And natural gap between training datasets and in-reality data may lead to unexpected AI system malfunction. Knowing underlying uncertainty is essential for reliability. Therefore, we developed...
