Griddler LLP is a company spun-off by Dr Johnson Wong from the Solar Energy Research Institute of Singapore (SERIS) in 2018. It undertakes further development and sales of the popular free release solar cell finite-element model (FEM) simulation program Griddler 2.5 developed at SERIS in 2013.
Griddler 2.5 solves the voltage and current distributions in the cell plane at arbitrary illumination and biasing conditions. Further, the user can easily define spatial variations in most recombination and resistance parameters, for instance the diode saturation current densities and emitter sheet resistance, either by importing a picture or via a built-in drawing interface. Finally, Griddler 2.5 supports the definition of both front and rear metallization geometries, and features a rigorous bifacial calculation mode.
Over time, Griddler evolved into a platform to design solar cells, calculate solar cell efficiency, quantify limiting factors, store published cell parameters gathered from all over the world, and predict the rooms for improvement by employing different design changes. It also works seamlessly with SolarEYE, which is a luminescence imaging platform that images and analyzes lab-based cells and wafer samples, allowing the researcher to understand what are the main areas to improve in actual cells that are made in the manufacturing environment. A lot of thought have been put in to make Griddler easy to use, practical, rigorous, and powerful. Further additions to the Griddler family include Griddler 2.5 PRO, Griddler IBC and Module.

Together, SERIS and Griddler facilitate both on-site and off-site consultancy projects in the areas of manufacturing line improvement, best practices implementations, process and tool evaluations, with flexible arrangements that provide results.
