Solar Research: On the Hunt for the Super-cell

European Sharc25 project aims to achieve 25 percent efficiency with thin-film solar cells

A new European research project that goes by the name Sharc25 is setting out to make an extremely efficient thin-film solar cell for the next generation of more cost-effective solar modules. Its objective is to achieve up to 25 percent efficiency in thin-film solar cells made by the coevaporation of copper indium gallium (di)selenide, or CIGS for short. That kind of performance would top the previous best mark by just over three percentage points. The Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) is coordinating the project. Eleven research partners from eight countries are on board. Launched in May, the project will run for 3.5 years and get €4.6 million in EU funding sourced from the research framework program Horizon 2020. The Swiss government is providing another €1.6 million. The results of this project could well give the European solar industry a boost.

Announcement: 2nd Sharc25 workshop in Dübendorf (Switzerland) on October 29, 2018

We are pleased to announce a workshop on “CIGS solar cells – advanced characterization and novel concepts” within the framework of the EU project Sharc25. This 2nd Sharc25 project workshop will be held at Empa in Dübendorf (Switzerland) on October 29, 2018.

AIM & SCOPE of the workshop
This full-day event will provide opportunities to learn about the advancements made through the Shrac25 project and to discuss with experts from the consortium and with external speakers on advanced characterization and novel concepts in CIGS solar cells. Key problems limiting the efficiencies and possible approaches for achieving efficiencies towards 25% will be discussed. Additionally, it is envisaged that interaction of academia and industry will identify topical research themes for supporting industrial developments and advancing state of the art of CIGS technology.

Please save the date October 29, 2018 for this interesting event. Details will follow in August 2018.

There is possibility to present a poster with your research results. If you are interested please indicate this during registration and send an abstract of no more than 10 lines to

Empa Ueberlandstrasse 129 8600 Dübendorf / Switzerland (Address for GPS / sat nav: Eduard-Amstutz-Strasse)

Empa Dübendorf is very close to Zurich airport and can be easily reached by public transport
