Single and multijunction InP-based photovoltaic devices for space applications

AIP Conference Proceedings, 1995
InP‐based multijunction tandem solar cells show great promise for high conversion efficiency and high radiation resistance. In this work, we present results on an InGaAs solar cell with a very high current density, 60 mA/cm2 (the highest ever reported), and an efficiency (η) of 10.2% under natural sunlight, and InP solar cell with η=18% under AM1 ...

Organic-inorganic hybrid tandem multijunction photovoltaics with extended spectral response

Applied Physics Letters, 2011
We demonstrate series-connected hybrid tandem multijunction photovoltaics by combining hydrogenated amorphous silicon (a-Si:H) and polymer-based organic photovoltaics (OPVs). To utilize the wide solar spectrum with cost-effective processes, we employed a solution-processed low band gap OPV subcell onto the a-Si:H subcell.

III–V multijunction solar cells for ultra-high concentration photovoltaics

2009 34th IEEE Photovoltaic Specialists Conference (PVSC), 2009
In this paper, the benefits of the ultra high concentration (≫ 1000 suns) are shown in terms of cost reduction and efficiency increase. Accordingly, the strategy followed at IES-UPM for more than 15 years is the development of III–V solar cells suitable for operation at 1000 suns or more.

The Segmental Approximation of Multijunction Solar Cell Photovoltaic Characteristics

2015
Today, the multi-junction solar cells have high theoretical efficiency for both concentrator and space applications. In this connection accurate modeling of the multi-junction solar cell photovoltaic characteristics is necessary. The proposed approaches use the advantages which are inherent in the mono-exponential (correspondingly semi-logarithmic ...

High-efficiency integrated multijunction photovoltaic/electrolysis systems for hydrogen production

International Journal of Hydrogen Energy, 2001
Abstract In this study, two integrated PV/electrolysis systems were studied. An integrated PV/electrolysis device is a device where the PV system and the electrolyser are combined into a single system. In the case studied here, the areas of the PV device and the electrolyzer are identical.
