    Abstract: The present disclosure generally relates to thin film liftoff processes for use in making devices such as electronic and optoelectronic devices, e.g., photovoltaic devices. The methods described herein use a combination of epitaxial liftoff and spalling techniques to quickly and precisely control the separation of an epilayer from a growth substrate. Provided herein are growth structures having a sacrificial layer positioned between a growth substrate and a sacrificial layer. Exemplary methods of the present disclosure include forming at least one notch in the sacrificial layer and spalling the growth structure by crack propagation at the at least one notch to separate the epilayer from the growth substrate.

The solar tracking system may have a first (22) and second (24) tracker module array that are opposite from another, aligned in substantially identical orientation, and form a tracker module pair array (1000). Tracker module pairs (12, 14; 12, 144) may allow motion relative to one another while maintaining substantially identical orientation. Solar concentrators may be attached to opposing tracker modules of a tracker module pair forming an array of solar concentrators. A base bar array (28) may be coupled to at least one tracker module pair. A transmission may operably rotate the base bar array and the tracker module pair array simultaneously.
