InP-Based Tunnel Junctions for Micro-Concentrator Photovoltaics

Photovoltaic Specialists Conference, 2023
To further improve the performance of mechanically stacked micro-concentrator photovoltaic devices, we have studied tunnel junctions for inclusion in triple junction solar cells that are fully lattice-matched to the InP template.

How Should Researchers Measure Perovskite‐Based Monolithic Multijunction Solar Cells’ Performance? A Calibration Lab's Perspective

Solar RRL, 2022
Perovskite multijunctions (PVSK MJs) have made remarkable progress with monolithic PVSK/PVSK tandems surpassing the efficiency of single‐junction (1 J) PVSK cells and PVSK/Si cells reported to exceed the 30% efficiency mark.

Graded Recombination Layers for Multijunction Photovoltaics

Nano Letters, 2012
Multijunction devices consist of a stack of semiconductor junctions having bandgaps tuned across a broad spectrum. In solar cells this concept is used to increase the efficiency of photovoltaic harvesting, while light emitters and detectors use it to achieve multicolor and spectrally tunable behavior.

Efficiency of multijunction photovoltaic systems

2008 33rd IEEE Photovolatic Specialists Conference, 2008
In this paper, an expression for the PV system efficiency is derived that can be used in conjunction with measured device performance and detailed numerical modeling to analyze PV system performance. Such an analysis will help identify design trade-offs and also help to identify which system and cell design changes will be of greatest benefit to the ...

Multijunction organic photovoltaics with a broad spectral response

Physical Chemistry Chemical Physics, 2012
We demonstrate series-integrated multijunction organic photovoltaics fabricated monolithically by vapor-deposition in a transposed subcell order with the near-infrared-absorbing subcell in front of the green-absorbing subcell. This transposed subcell order is enabled by the highly complementary absorption spectra of a near-infrared-absorbing visibly ...
