Interdigitated back‐contacted structure: A different approach towards high‐efficiency ultrathin copper indium gallium (di) selenide solar cells.

An interdigitated back-contacted (IBC) configuration is proposed for submicron copper indium gallium (di)selenide (CIGS). In a modelling platform, the structure was opto-electrically optimized for maximum efficiency. The results are compared with a reference front/back-contacted (FBC) solar cell with similar absorber thickness and exhibiting 11.9% efficiency. The electrical passivation at the front side is accomplished by […]

Comparative Building Energy Simulation Study of Static and Thermochromically Adaptive Energy-Efficient Glazing in Various Climate Regions.

The building sector contributes approximately one third of the total energy consumption worldwide. A large part of this energy is used for the heating and cooling of buildings, which can be drastically reduced by use of energy-efficient glazing. In this study, we performed building energy simulations on a prototypical residential building, and compared commercially available […]

Small-scale Bioclimatic Prosthesis: A strategy for adaptive social housing based on local spontaneous and socio-environmental patterns in transitional spaces

In Latin America, there is a huge existing housing stock that no meets the minimum requirements for thermal comfort and energy efficiency, built before relatively recent thermal regulations. The scarcity of climate adaptive possibilities and the lack of design in the transitional spaces that these buildings create is identified as a common pattern throughout the […]

Getting innovations adopted in the housing sector.

Purpose: The purpose of this study is threefold. First, to provide a taxonomy of innovations in the housing sector. Second, to create a coherent framework that includes the mechanisms that stimulate and hinder the adoption of innovation in the housing sector. Third, to develop propositions for future innovation adoption research. Design/methodology/approach: A search in Clarivate […]

The influence of glass substrates on the damp heat degradation of ZnO: Al films

Aluminum doped zinc oxide (ZnO:Al) films were deposited by sputtering on borosilicate glass (sodium poor) and soda lime glass (sodium rich). These films were exposed up to 1032 hours of damp heat (85 ◦C/85 % relative humidity) to study the influence of among others the sodium content of the substrate on the ZnO:Al stability. A […]

Phase separation of VO2 and SiO2 on SiO2-Coated float glass yields robust thermochromic coating with unrivalled optical properties.

Vanadium dioxide displays thermochromic properties based on its structural phase transition from monoclinic VO2 (M) to rutile VO2 (R) and vice versa, and the accompanying reversible metal-insulator transition. We developed a single layer coating comprising VO2 (M) and SiO2. We applied the coating from an alcoholic solution comprising vanadium(IV) oxalate complex and pre-oligomerized tetra ethoxy […]
