SunLab BV is a daughter company of Energy research Centre of the Netherlands. SunLab was founded in 1999 to commercialize special products of ECN Solar Energy. SunLab offers three instruments: Corescan, Sherescan and SunLab B2B.

The mission of SunLab is dedicated to service and support the PV industry by realizing efficient and cost effective solar cells and modules.

The Corescan instrument was brought to the market in 2000 and in 2005 the Sherescan instrument was introduced. SunLab B2B is the latest instrument, and available since 2010. The Corescan and Sherescan are successfully used to optimize, control and diagnose processes by cell manufacturers, solar thick film paste suppliers, institutes and universities all over the world. SunLab B2B is indispensable for process control, cell optimization and diagnosis in case of material and cell development and cell manufacturing.

Sherescan - instrument for mapping Sheet Resistance of emitter
To achieve high efficiency crystalline silicon solar cells, the uniformity and reproducibility of the emitter plays a major role. The knowledge of the emitter sheet resistance across the surface of a single wafer, and of the reproducibility from wafer to wafer is essential in optimizing the emitter diffusion process.
Sherescan instrument also offers other modes of measurement: P/N recognition, and metal conductivity.

SunLab B2B – instrument for measuring busbar to busbar resistance
To achieve high efficiency solar cells, series resistance plays a major role, and front side grid resistance is one of the components. The front side grid resistance on its turn is dependent on the print definition and print quality. A practical assessment of the grid resistance & print quality is to measure the resistance in between two busbars (B2B resistance). SunLab B2B is made for measuring the resistance of all fingers between two busbars on an H-pattern solar cell.
