Technology and R&D

Fraunhofer ISE has worked with German technology companies to improve the metallization process in silicon solar cells. The result could drive down module costs quite a bit.

With the 200 hydrogen bikes offered to journalists and world leaders at the G7 summit in Biarritz proving popular, manufacturer Pragma Industries has received an order for 1,000 of them from Chilean president Sebastian Pinera. The company’s founder, Pierre Forté, wants the bike to have a societal impact in developing countries.

A consortium of European research institutes has received €10.6 million in EU funding to establish pilot production of a high efficiency module concept developed by Swiss startup Insolight. The module combines high efficiency multijunction cells with a solar concentrator lens and has previously demonstrated 29% efficiency.

Two of Germany’s leading research institutes and a CIGS module maker have announced plans to work on the development of perovskite-CIGS tandem cells with a target of producing thin film modules with better than 30% efficiency.

Vehicle-to-grid functions could soon become increasingly important. While policymakers discuss the necessary regulations in other nations, the Netherlands government is motoring ahead with the technology.

An increasing number of carmakers and research institutes are developing concepts that combine e-mobility and solar. Thus far, range additions from in-car panels of between 10 and 60km are the limit of innovation. The Fraunhofer roof is tinted with a color that hides the cells but lets through most of the light.

Scientists at the institution have achieved 21.6% efficiency with a perovskite cell measuring 1cm². The landmark has been verified as a new world record for perovskites at this size.

The Indian state plans to achieve half the amount by 2021-22 under its new draft solar policy. The package also suggests establishing a research hub, privately financed solar parks and encouraging commercial self-consumption of clean energy.

Another study has highlighted the advantages of combining solar with agriculture. According to the paper, growing chiltepin pepper, jalapeno and cherry tomato in dryland areas of the U.S. under the shade of PV modules is not only possible, but can lead to a better harvest.

A new coating developed by scientists at Stanford promises to bring lithium metal batteries ‘closer to reality’, by significantly extending their operational lifetime and limiting the occurrence of dendrites at the anode, which can cause short circuiting and fires.
