Solar module efficiency exceeds 43 percent

Solar module efficiency exceeds 43 percent

Technology News |
In the world of solar cells, the highest efficiency is achieved by Concentrated Photovoltaic cells (CPV). And there still seems to be a lot of potential in this technology: The Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) claims to have achieved a record efficiency for this technology: A module based on quadruple solar cells boasts an efficiency of 43.4 percent. Just two years ago, Fraunhofer ISE has already set a record with this technology, albeit at cell level.

In the CPV technology, the cells are typically implemented as multi-junction cells. In geographic regions with high direct sun irradiation, this technology is ideal to generate electricity out of renewable sources at low cost. In 2014, ISE along with partners Soitec and CEA Leti had set an efficiency record for a quad-junction. The mini-module recently introduced to the public is based on the multi-junction solar cell similar to the 2014 record cell, but additional concentrator optics has been added, resulting in another record value for the efficient conversion of solar radiation into electric power.

 

“This is a new milestone for the CPV technology and highlights the potential of this technology for future industrial implementations”, commented Andreas Bett, deputy manager at Fraunhofer ISA (Freiburg, Germany).
