“…One potential hurdle to overcome is acceptance of their unmistakable appearance -LSCs are bright, colorful and indiscrete! However, a recent study using a red LSC as a power-generating window in an office environment was judged favorably by volunteer participants when compared to a normal, clear glass window, [177] suggesting that market acceptance is not a key barrier to commercialization of this technology.…”

Single-junction photovoltaic devices exhibit a bottleneck in their efficiency due to incomplete or inefficient harvesting of photons in the low- or high-energy regions of the solar spectrum. Spectral converters can be used to convert solar photons into energies that are more effectively captured by the photovoltaic device through a photoluminescence process. Here, recent advances in the fields of luminescent solar concentration, luminescent downshifting, and upconversion are discussed. The focus is specifically on the role that materials science has to play in overcoming barriers in the optical performance in all spectral converters and on their successful integration with both established (e.g., c-Si, GaAs) and emerging (perovskite, organic, dye-sensitized) cell types. Current challenges and emerging research directions, which need to be addressed for the development of next-generation luminescent solar devices, are also discussed.

“…This same dye was also used in an LSC acting as a south-facing face in an office, with the conclusion that LSC integration is compatible and advantageous in terms of visual comfort [6]. Another study quantified the maximum level of coverage an LSC, albeit a red dye doped one, on a facade is 25%, for both interior and exterior viewing [7]. The potential for LSC stained-glass window designs has been reported on, and 3D ray-trace models have been created which have been confirmed experimentally to be useful for optimising LSCs in various shapes and sizes [8].…”

This paper presents an investigation of the geometric effects within a cylindrical array luminescent solar concentrator (LSC). Photon concentration of a cylindrical LSC increases linearly with cylinder length up to 2 metres. Raytrace modelling on the shading effects of circles on their neighbours demonstrates effective incident light trapping in a cylindrical LSC array at angles of incidence between 60-70 degrees. Raytrace modelling with real-world lighting conditions shows optical efficiency boosts when the suns angle of incidence is within this angle range. On certain days, 2 separate times of peak optical efficiency can be attained over the course of sunrise-solar noon. (2012) https://github.com/danieljfarrell/PVTRACE.

“…Using QDs in windows/skylights has advantages of low cost, easy fabrication, highly efficient, controllable transparency, tunable shading degree, and flexible design [74][75][76]. Vossen et al [77] studied the impact of a red LSC on the visual comfort and impression of volunteer participants in an office building. Three identical physical models were created for a 1.8 × 2.7 × 3.9 m 3 room; two of them for participant evaluation and another for daylight measurements.…”

Review of Core/Shell Quantum Dots Technology Integrated into Building’s Glazing

Skylights and windows are building openings that enhance human comfort and well-being in various ways. Recently, a massive drive is witnessed to replace traditional openings with building integrated photovoltaic (BIPV) systems to generate power in a bid to reduce buildings’ energy. The problem with most of the BIPV glazing lies in the obstruction of occupants’ vision of the outdoor view. In order to resolve this problem, new technology has emerged that utilizes quantum dots semiconductors (QDs) in glazing systems. QDs can absorb and re-emit the incoming radiation in the desired direction with the tunable spectrum, which renders them favorable for building integration. By redirecting the radiation towards edges of the glazing, they can be categorized as luminescent solar concentrators (QD-LSCs) that can help to generate electricity while maintaining transparency in the glazing. The aim of this paper is to review the different properties of core/shell quantum dots and their potential applications in buildings. Literature from various disciplines was reviewed to establish correlations between the optical and electrical properties of different types, sizes, thicknesses, and concentration ratios of QDs when used in transparent glazing. The current article will help building designers and system integrators assess the merits of integrating QDs on windows/skylights with regards to energy production and potential impact on admitted daylighting and visual comfort.
