Metal Wrap Through (MWT) solar cell represents a type of back-contact solution which allows to improve the efficiency of conventional silicon photovoltaic (PV) cells. In this work we use TCAD numerical simulations to investigate the performance of MWT cells. The impact of critical parameters, such as the resistance of VIA, the separation region and the busbar width is analyzed. The study of the main figures of merit under illumination and in dark condition allows to understand the physical mechanisms which limit the conversion efficiency.

Abstract
Metal Wrap Through (MWT) solar cell represents a type of back-contact solution which allows to improve the efficiency of conventional silicon photovoltaic (PV) cells. In this work we use TCAD numerical simulations to investigate the performance of MWT cells. The impact of critical parameters, such as the resistance of VIA, the separation region and the busbar width is analyzed. The study of the main figures of merit under illumination and in dark condition allows to understand the physical mechanisms which limit the conversion efficiency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
