| Popis: | 26th European Photovoltaic Solar Energy Conference and Exhibition; 1257-1261 DuPont Innovalight’s CougarTM Platform is a selective emitter (SE) process based on a screen-printed pattern of Silicon Ink. This report presents the optimization of the Cougar cell for photovoltaic (PV) modules. Raytracing modeling has been used to optimize the performance of encapsulated Cougar cells, taking into account the optical properties of surface texture, encapsulant materials, and cell anti-reflection coating layers. Anti-reflection coatings are made from silicon nitride (SiNx), the optical characteristics of which were determined from ellipsometry and UV-Vis spectroscopy. Modeling predicts different cell-to-module (CTM) performance ratios for short-circuit current (Isc), depending on the SiNx characteristics. Mini-modules were constructed to verify modeling results. In addition to optical modeling, fill factor losses in the mini-modules are investigated and analyzed. Accelerated lifetime testing was also performed. The Cougar Platform shows equivalent reliability performance compared to traditional, homogeneous emitter (HE) solar cells. |
