SunLab offers three instruments: Corescan, Sherescan and SunLab B2B

We are proud to introduce our latest instrument: Sherescan 2.0 that enables you to measure selective emitters in a quantitative way. 

Corescan - instrument for mapping of Contact Resistance of front side grid

Corescan is used for detailed surface mapping of contact resistance between the emitter and the metallization grid of solar cells. Other standard mapping modes in the instrument are for shunt resistance; short circuit current (LBIC) and open circuit voltage (Voc). Corescan instrument is indispensable for optimisation of cell efficiency, trouble shooting and R&D. 

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, metal conductivity and NEW selective emitter. 

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.


About Sunlab

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.

The mission of SunLab is to make measurement instruments that support the PV industry to realize efficient and cost effective solar cells and modules. As we are on top of the latest research activities we are able to continuously deliver new measurement applications to support your new solar cell and module developments.

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.
