Modeling of the hydrogen selective emitter for n-type silicon solar cells

A simulation of the Hydrogen Selective Emitter (HSE) process is performed using readily available open source software from PV Lighthouse. An experimental boron (B) profile from Yingli solar is analyzed using EDNA 2 and this output is used with PC1D to create inputs for Griddler 2. Griddler allows for the simulation of cell parameters for a full size bifacial type device. We find that an efficiency boost of 0.2 to 0.4% absolute is possible by applying the HSE process to an experimental n-type silicon solar cell. We also show that the number of silver (Ag) gridlines at the front of the cell could be reduced by 33% while gaining at least 0.14% in efficiency over the baseline cell.
