Abstract :
In commercial production, Solarex´s baseline multicrystalline solar cells are 130 cm2 in area with an average efficiency of approximately 13%. One of the goals of Solarex´s Photovoltaic Manufacturing Technology (PVMaT) program (sponsored by NREL), is the development of a cost-effective cell process to achieve an average cell efficiency of 15% on large-area substrates. In this paper, the details of the efforts to scale-up the area of the cells from 130 cm2 to 230 cm2 and the details of the development of an integrated high efficiency solar cell process sequence are reported
