Abstract:
ECN has developed a new cell and module design for crystalline siliconsolar cells called PUM (pin-up module). In this design a limited number of
holes (typically 9 or 16) is used to interconnect the front side
metallization to a foil at the rear side by using pins. In this way the bus
bars and tabs at the front side are eliminated resulting in several important
benefits. The efficiency of the cell becomes independent of the cell area and
the efficiency is higher compared to standard tabbed cells. Another benefit
is the visual appearance. In this paper we discuss the design of the
metallization pattern for the cells. A theoretical analysis is presented that
shows the gains of the PUM design over conventional cells. 10 refs.
