Energy‐Level Engineering with Co‐Sensitization of Organic Molecules on NiOx for Sn‐Based Perovskite Solar Cells

open access: yesSmall, EarlyView.
Mixed molecular self‐assembly of functionalized bithiophene (BT) and dithienopyrrole (DTP) units on NiOx HTL synergistically modulate the Fermi Level to induce barrier‐free hole injection in both ITO/HTL and HTL/Sn‐perovskite interfaces in the inverted p‐i‐n device configuration.

How We Simulate Nanopores

open access: yesSmall Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Comparative study of modern heuristic algorithms for global maximum power point tracking in photovoltaic systems under partial shading conditions

open access: yes, 2022
Under partial shading conditions (PSCs), photovoltaic (PV) generation systems exhibit multiple local and a single global maximum power point. Consequently, global maximum power point tracking (GMPPT) is required to improve the performance of PV systems ...

A novel newton-Raphson-based optimizer for MPPT: Enhancing efficiency in partially shaded PV systems with experimental validation

open access: yesResults in Engineering
This paper presents an experimental investigation of a Newton–Raphson-Based Optimizer (NRBO) for global maximum power point tracking (GMPPT) in photovoltaic (PV) systems under partial shading conditions (PSCs) and dynamic shading conditions (DSCs ...

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

open access: yesStructural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Structural testing and analytical model of Reinforced Concrete (RC) prisms with 3D‐printed concrete permanent formwork under compressive loading

open access: yesStructural Concrete, EarlyView.
Abstract The implementation of traditional steel reinforcement in 3D concrete printed structures is a major challenge. Although 3D‐printed structures may be used as formwork, the knowledge about their structural contribution is limited. This research aims to experimentally evaluate the structural performance of reinforced concrete prisms with 3D ...

Comparative analysis of conventional and modified perturb and observe MPPT controllers under partial shading conditions

open access: yes, 2021
Sun-oriented energy is one of the most unswerving energy for its abundance, non-conventional, and pollution-free nature, and it is primarily reliant upon temperature and irradiance conditions. The current and voltage (I-V) curve shows a single peak point

Technology, Work Intensification and Burnout*

open access: yesEconomic Record, EarlyView.
We model how technologies that allow managers to directly communicate with and more closely monitor employees can lead to an intensification of work, heightening employee vulnerability to burnout. When multiple managers assign tasks simultaneously, like in a matrix organisation, employees can become overburdened, decreasing their productivity and well ...
