INVESTIGATION OF CELL PERFORMANCE WITH DIFFERENT FIRING TECHNIQUE ON BIFACIAL SOLAR CELL

Abstract

Fire-through metallization is the most common method for forming front and back contact on screen-printed silicon solar cells. Screen printing technique typically used in industrial metallization due to its cost-effectiveness, rapid and simple production, compared to the photolithography and buried-contact techniques which is time-consuming and expensive. Another problem occured during firing is Ag shunting junction. In this study, an alternative way of firing process, namely Quatrz Tube Furnace (QTF) was investigated. QTF is a non conveyer belt furnace that can be heated until 1200°C. Two different temperature were used which is 700 and 750°C. As temperature increased, the electrical properties of bifacial solar cell also increased. Premilinary results shows that the QTF can be used as the alternative way for firing process in Si solar cell fabrication.
