Advances in High Efficiency Back Contact Back Junction Solar Cells

In the past few decade’s researchers, scientists, engineers of photovoltaic (PV) industry are working towards low cost high efficiency Si solar cells. Over the last decade the interest in back contact solar cell has been acquiring as well as a gradual introduction to industrial applications is increasing. As an alternative to conventional solar cells with a front and rear contact, the back-contact cells has remained a research topic. The aim of this work is to present a comprehensive summary of results incurred in the back contact back junction solar cells such as interdigitated back-contact (IBC), emitter wrap-through (EWT) and metallization wrap-through (MWT) over the years.
