  title={Demonstration of a novel dispersive spectral splitting optical element for cost- effective photovoltaic conversion},
  author={Carlo Maragliano and Tim Milakovich and Matteo Bronzoni and Stefano Rampino and Eugene A. Fitzgerald and Matteo Chiesa and Marco Stefancich},
  journal={arXiv: Optics},
In this letter we report the preliminary validation of a low-cost paradigm for photovoltaic power generation that utilizes a prismatic Fresnel-like lens to simultaneously concentrate and separate sunlight into continuous laterally spaced spectral bands, which are then fed into spectrally matched single-junction photovoltaic cells. A prismatic lens was designed using geometric optics and the dispersive properties of the employed material, and its performance was simulated with a ray- tracing…

Spectral light management for solar energy conversion systems

Abstract Due to the inherent broadband nature of the solar radiation, combined with the narrow spectral sensitivity range of direct solar to electricity devices, there is a massive opportunity to

Photovoltaics in Van der Waals Heterostructures

The peculiar nature of light-matter interaction in atomically thin transition metal dichalcogenides is recently under examination for application in novel optoelectronic devices. Here, we show that



Point-focus spectral splitting solar concentrator for multiple cells concentrating photovoltaic system

In this paper we present and experimentally validate a low-cost design of a spectral splitting concentrator for the efficient conversion of solar energy. The optical device consists of a dispersive

New Efficiency Frontiers with Wafer-Bonded Multi-Junction Solar Cells.

Triple-junction (3J) solar cells will soon be history. The next generation of multi-junction (MJ) devices are now reaching efficiencies far beyond the record levels of 3J cells on Germanium. In this

Three-Dimensional Cu(InGa)Se$_{\bf 2}$ Photovoltaic Cells Simulations: Optimization for Limited-Range Wavelength Applications

One of the main challenges in Cu(InGa)Se2 (CIGS) solar cells modeling is due to the complex microcrystalline structure of the absorber layer. A CdS/CIGS solar cell that is modeled as an array of

III–V multijunction solar cells for concentrating photovoltaics

Concerns about the changing environment and fossil fuel depletion have prompted much controversy and scrutiny. One way to address these issues is to use concentrating photovoltaics (CPV) as an

Fundamental losses in solar cells

This paper considers intrinsic loss processes that lead to fundamental limits in solar cell efficiency. Five intrinsic loss processes are quantified, accounting for all incident solar radiation. An

Multiple-bandgap vertical-junction architectures for ultra-efficient concentrator solar cells

A novel multiple-bandgap multi-terminal vertical-junction (side-illumination) architecture for concentrator solar cells is proposed and simulated, wherein each stacked sub-cell operates at its own

Germanium-on-Glass solar cells: fabrication and characterization

We report on Germanium on Glass solar cells realized by wafer bonding, layer splitting and epitaxial regrowth. We provide a detailed description of the layer transfer process and discuss the material
