    摘要： 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.

    摘要： The present disclosure generally relates to organic photosensitive optoelectronic devices comprising at least one boron dipyrrin compound. In addition, the present disclosure relates to methods of making organic photosensitive optoelectronic devices comprising at least one boron dipyrrin compound. The present disclosure also generally relates to chromophoric compounds that combine strong absorption of light at visible wavelengths with the ability to undergo symmetry-breaking intramolecular charge transfer (ICT), and their use for the generation of free carriers in organic photovoltaic cells (OPVs) and electric-field-stabilized geminate polaron pairs. The present disclosure also relates to the synthesis of such compounds, methods of manufacture, and applications in photovoltaic systems and organic lasers.
