Protemics and ECN join forces on Terahertz analytics for photovoltaic applications

THz Solar Analytics

Aachen/Petten – Non-destructive testing is one of the most important applications of recent technological developments operating in the spectral range of Terahertz (THz) frequencies. For example, THz radiation is able to unveil sheet resistance distributions and charge carrier dynamics in semiconductors or thin-film conductors also under difficult situations such as on rough or passivated surfaces.

However, the inspection of micron-scale structures as found in newly developed solar cell structures requires advanced sensors that are able to break the millimeter-scale optical resolution limits of THz light and enable analytic results sufficiently detailed for the optimization of solar cell fabrication processes.

Protemics GmbH (Aachen, Germany) and Energy Research Centre of the Netherlands ECN (Petten, The Netherlands) have now officially announced their agreement on a joint venture targeting the development and commercialization of advanced THz analytics for photovoltaic (PV) applications. Protemics will contribute its proprietary Terahertz technology including "TeraSpike" high-resolution microprobe sensors as well as further key components for a new wafer-scale scanning system providing automated imaging of sheet-resistance distributions and carrier life-time information. The measurement speed of the new contactless system will be three orders of magnitude faster than four-point-probe testing and offer more than 100-times higher spatial resolution (10 µm) than any contactless system available on the market.

ECN will bring in its long lasting experience as industrial based PV process technology developer and developer of analytic tools for the PV market. Within the partnership Protemics and ECN will develop a THz measuring tool dedicated for solar cell measurements. ECN will be responsible for the application development and the introduction of the tool to the PV sector. The tool will become available in the last quarter of 2015.
