Theory of random nanoparticle layers in photovoltaic devices applied to self-aggregated metal samples
Christin David, James P. Connolly, Christian Chaverri Ramos +2
Random Al and Ag nanoparticle distributions are studied on varying substrates, where we exploit the nanosphere self-aggregation method (NSA) for fabrication. Relying on the measure…
Quantum Wells in Photovoltaic Cells
C Rohr, P Abbott, I M Ballard +4
The fundamental efficiency limit of a single bandgap solar cell is about 31% at one sun with a bandgap of about Eg = 1.35 eV (1), determined by the trade-off of maximising current…
Short circuit current enhancement in GaAs/AlGaAs MQW solar cells
James P. Connolly, Keith W. J. Barnham, Jenny Nelson +3
The GaAs/AlGaAs quantum well solar cell (QWSC) shows promise as a novel approach to higher efficiency solar cells but suffers from a poor short circuit current Jsc. We report on ef…
Multiscale approaches to high efficiency photovoltaics
J. P. Connolly, Lejo J. Koduvelikulathu, D. Mencaraglia +3
While renewable energies are achieving parity around the globe, efforts to reach higher solar cell efficiencies becomes ever more difficult as they approach the limiting efficiency…
Growth Route Toward III-V Multispectral Solar Cells on Silicon
C. Renard, N. Cherkashin, A. Jaffré +8
To date, high efficiency multijunction solar cells have been developed on Ge or GaAs substrates for space applications, and terrestrial applications are hampered by high fabricatio…
Designing III-V Multijunction Solar Cells on Silicon
J. P. Connolly, D. Mencaraglia, C. Renard +1
Single junction Si solar cells dominate photovoltaics but are close to their efficiency limits. This paper presents ideal limiting efficiencies for tandem and triple junction multi…
III-V Solar Cells
James P. Connolly, Denis Mencaraglia
III-V materials show a wide range of gaps making them ideal for the design of high efficiency solar cells. This chapter reviews relevant growth methods and material properties of t…
Analytical Models of Bulk and Quantum Well Solar Cells and Relevance of the Radiative Limit
James P. Connolly
The analytical modelling of bulk and quantum well solar cells is reviewed. The analytical approach allows explicit estimates of dominant generation and recombination mechanisms at…
Modelling Multi Quantum Well Solar Cell Efficiency
James P. Connolly, Jenny Nelson, Ian Ballard +5
The spectral response of quantum well solar cells (QWSCs) is well understood. We describe work on QWSC dark current theory which combined with SR theory yields a system efficiency.…
