A “life cycle thinking” approach to assess differences in the energy use of SiC vs. Si power semiconductors

Wide bandgap (WBG) semiconductors have the potential to provide significant improvements in energy efficiency over conventional Silicon (Si) semiconductors. While the potential for energy efficiency gains is widely researched, the relation to the energy use during manufacturing processes remains insufficiently studied. This question is especially relevant for Silicon carbide (SiC) semiconductors, as there are some key differences in their production processes compared to Si. This paper aims to identify the main differences of the SiC


Switching Elements of the Thrifty Variety – GERMAN

Abstract: From cell phones to cars to data centers: The diverse electrical applications that visibly and invisibly shape our everyday life all contain switching elements made of semiconductor materials. These powerful electronic components have huge energy-savings potential that can be realized by using so-called wide-bandgap semiconductors. This is the conclusion of an expert report of the International Energy Agency’s Technology Program 4E, in which Swiss experts are significantly participating. See also the webpage of Swiss


4E PECTA Factsheet for Term 2020 – 2024 (established phase)

PECTA is a collaboration of the governments of Austria, Denmark, Sweden and Switzerland. The PECTA factsheet shares some basic information about PECTA goals and actual running tasks. Currently (January 2021) six tasks are up and running. For more information please download our factsheet.


Huge energy-savings by WBG semiconductors

This is one of the latest articles published by the Swiss Federal Office of Energy (SFOE) related to wide bandgap technology, and its potential promising applications for SiC and GaN Semiconductors.


PECTA Pre-scoping study – New power electronic materials and devices and its impact on the energy efficiency – Assessment Study for 4E Annex preparation

In the beginning of 2017, a new Annex to the IEA 4E TCP (Technology Collaboration Program of Energy Efficient End-Use Equipment) has been planned. The Power Electronic Conversion Technology Annex (PECTA) is designed as a platform to assess the efficiency benefit of using the emerging WBG technology. This report is part of the PECTA preparation and by no means a technical publication. Based on this report the documents for PECTA have been elaborated and submitted
