    Abstract

    Thin (<70 micron) single crystal silicon solar cells have been manufactured through the use of a novel process involving selective etching. Narrow grooves are micromachined through the wafer using a standard micromachining technique with cells manufactured on the resulting silicon strips. These bifacial cells have a much greater surface area than the original wafer, leading to dramatic decreases in processing effort and silicon usage. Individual cells fabricated using the new process have displayed efficiencies up to 17.5% while a 560cm2 prototype module has displayed an efficiency of 12.3%. The size, thickness and bifacial nature of the cells offer the opportunity for a wide variety of module architectures and applications.
