High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Urban Growth [PDF]

open access: yes, 1997
This paper models and examines empirically the evolution of cities in an economy. Twentieth century evolution in the USA is characterized by parallel growth of cities of different types and on-going entry of new cities, together maintaining a stable relative size distribution of cities. Each type of city has a particular industrial composition and good(

Long-term dynamics of European towns and cities: towards a spatial model of urban growth

open access: yesCybergeo, 2000
The aim of the study is to elaborate a model in the framework of self-organisation theory which would describe how interactions between individual towns and cities can produce macro-geographical structures and dynamics at the scale of a continental urban

Reliable and Reusable All‐Solid‐State Contact‐Type Pre‐Lithiation Platform for High‐Performance All‐Solid‐State Batteries

open access: yesAdvanced Materials, EarlyView.
A reusable contact‐type pre‐lithiation platform enables uniform, precisely controllable pre‐lithiation at low stack pressure, suppressing interfacial degradation and thereby markedly improving initial Coulombic efficiency and cycling performance in all‐solid‐state batteries.

Causes of residential mobility and Turkey practice

open access: yesTeMA: Journal of Land Use, Mobility and Environment, 2020
Residential mobility is an economic and social recovery process that determines urban growth and regional development. The urban population relocates due to the events in their lives or their dissatisfaction with the conditions. Such individual movements

“Cool” Roofs as a Heat-Mitigation Measure in Urban Heat Islands: A Comparative Analysis Using Sentinel 2 and Landsat Data

open access: yesRemote Sensing, 2022
Urban growth, characterized by expansion of impervious at the cost of the natural landscape, causes warming and heat-related distress. Specifically, an increase in the number of buildings within an urban landscape causes intensification of heat islands ...

Topology‐Orchestrated Multi‐physical Energy Control in Turtle Shell‐Inspired Metamaterials

open access: yesAdvanced Materials, EarlyView.
A turtle shell‐inspired lattice metamaterial efficiently manages acoustic, fluid‐thermal, and mechanical energy flows simultaneously. The unique hybrid‐coupling architecture achieves superior sound attenuation via pore‐cavity resonance, facilitates effective airflow transport, and maximizes mechanical energy absorption through multistage cell ...
