Abstract: A visibly transparent luminescent solar concentrator (LSC) is disclosed. The LSC includes a transparent substrate having at least one edge surface. A dye layer is coupled to the substrate, the dye layer having a peak absorption wavelength outside the visible band, the dye layer being configured to re-emit light at a peak emission wavelength outside the visible band, at least a portion of the re-emitted light being waveguided to the edge surface of the substrate. A photovoltaic device is coupled to the edge surface of the transparent substrate, the photovoltaic device being configured to absorb light at the peak emission wavelength and generate electrical energy.

Abstract: Disclosed are vapor transport deposition systems and methods for alternating sequential vapor transport deposition of multi-component perovskite thin-films. The systems include multiple vaporizing sources that are mechanically or digitally controlled for high throughput deposition. Alternating sequential deposition provides faster sequential deposition, and allows for reduced material degradation due to different vapor temperatures.
