In March 2016, international experts from Germany, Japan, the USA and other countries met in Freiburg for the first GA-SERI Terawatt Workshop. The experts came together last year to discuss what barriers still need to be overcome so that the worldwide climate targets can be met by photovoltaics. The Global Alliance of Solar Energy Research Institutes GA-SERI is made up of the Fraunhofer Institute for Solar Energy Systems ISE, the National Institute of Advanced Industrial Science and Technology AIST (Japan) and the National Renewable Energy Laboratory NREL (USA). Due to its rapid decrease in cost, PV technology is becoming more and more attractive as a cost-effective decentralized electricity supply for households and industry. Representatives from research institutes and industry as wells as from funding and financial organizations convened at the workshop, which was promoted by the German Federal Environmental Foundation DBU.

The main result of the workshop is an article, which has now been published in Science. The article can be accessed from the website of the U.S. Energy Department’s NREL Institute.
