An optical system and method to overcome luminescent solar concentrator inefficiencies by resonance-shifting, in which sharply directed emission from a bi-layer cavity into a glass substrate returns to interact with the cavity off-resonance at each subsequent reflection, significantly reducing reabsorption loss en route to the edges. In one embodiment, the system comprises a luminescent solar concentrator comprising a transparent substrate, a luminescent film having a variable thickness; and a low refractive index layer disposed between the transparent substrate and the luminescent film.

Resonance-shifting luminescent solar concentrators

Mono- and diimide perylene and naphthalene compounds, N- and/or core-substituted with electron-withdrawing groups, for use in the fabrication of various device structures.

N-type semiconductors and related devices

Mono- and diimide perylene and naphthalene compounds, N- and core-substituted with electron-withdrawing groups, for use in the fabrication of various device structures.

Perylene n-type semiconductors and related devices

Provided are mono- and diimide naphthalene compounds for use in the fabrication of various device structures. In some embodiments, the naphthalene core of these compounds are mono-, di-, or tetra-substituted with cyano group(s) or other electron-withdrawing substituents or moieties. Such mono- and diimide naphthalene compounds also can be optionally N-substituted.
