Technology Assessment

Around 90 % of solar cells manufactured today are based on crystalline silicon. The efficiency, price-to-performance ratio, long-term stability and potential for further cost reduction indicate that this peak performer in terrestrial PV will continue to dominate the market in the future. At Fraunhofer ISE we cover the entire value chain of crystalline silicon photovoltaics: from material research through to quality assurance for modules and power plants. Our R&D spectrum is set up to promote the introduction of new innovative products on the market in cooperation with industry. We aim to reduce manufacturing costs and support the PV industry in Germany and throughout Europe to compete internationally.

The scientific research platform on silicon materials at Fraunhofer ISE carries out research on all processing steps from the crystallization of mono and multi-crystalline ingots up to block sawing, polishing and wafering processes. In 2015, the new company NexWafe GmbH was founded in order to transfer the new manufacturing process, developed at Fraunhofer ISE for epitaxially grown wafers, to the production level. This groundbreaking drop-in technology is called “kerfless wafer” technology.

In 2015 Fraunhofer ISE achieved a new world record of 25.1% for both sides contacted silicon solar cells with its TOPCon technology. This technology is based on a thin tunnel oxide on which a highly doped Si layer is deposited. The selective contacts produced in this way allow only one type of charge carrier to pass. The TOPCon technology has great potential and the Institute is currently working on the industrial exploitation.

At Fraunhofer ISE’s Photovoltaic Evaluation Center PV-TEC, new processes and equipment are constantly being tested. Among the present tasks, novel prototypes to extrude metal pastes for creating highly conductive, thinner and higher contacts during manufacturing are under development. Also, the use of sheets and local laser alloying for the metallization of back-sided passivated solar cells is being investigated.

Tandem silicon solar cells are still a young field of research. The efficiency potential of these novel solar cells greatly exceeds that of the pure silicon solar cell. With its collective long-standing expertise in the field of III-V, perovskite and silicon solar cell technologies, Fraunhofer ISE holds the ideal prerequisites for achieving successful results in this young research field.

In the field of module technology, our research also focuses on optimum efficiency, reduced costs and maximum reliability.

As a complement to our research and development work in the research topic Silicon Photovoltaics, we offer related testing and certification services to clients.
