Optimization tool for multijunction photovoltaic systems
2014 IEEE 40th Photovoltaic Specialist Conference (PVSC), 2014The choice of individual bandgaps is important for achieving the maximum efficiency of a multijunction photovoltaic system. The optimization tool described in this paper uses a multijunction photovoltaic (PV) model and determines the bandgap energies that yield the highest possible system power efficiency for a given number of PV junctions.

High Efficiency Multijunction Photovoltaic Development
Industrial & Engineering Chemistry Research, 2012Photovoltaic energy conversion has demonstrated remarkable improvements in performance over the past 60 years. The rate of solar cell efficiency change has actually increased over the past 20 years as researchers have moved beyond elemental semiconductors to increasingly more sophisticated materials and devices. In addition, significant improvements in

Peak efficiency of multijunction photovoltaic systems
2010 35th IEEE Photovoltaic Specialists Conference, 2010The maximum efficiency of multijunction photovoltaic systems is determined for independently connected solar cells that are optically in series. The maximum efficiency is computed as a function of solar concentration using both the Shockley-Queisser detailed balance radiative limit for the reverse saturation current density and a simple empirical ...

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
In the present paper a novel configuration of high concentrator photovoltaic (HCPV) systems based on Cassegrain optics has been presented. The proposed system has been designed in order to be suitable for the implementation of both multi-junction and spectrum splitting configurations. The Cassegrain optic design, the components and material choices for

The design of multijunction photovoltaic systems for realistic operating conditions
2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013The design of a multijunction photovoltaic system, particularly the choice of the individual bandgaps, is sensitive to the specific operating conditions of the system. Laboratory characterization is typically carried out at a standard temperature, such as 25 °C, using a standard solar spectrum, such as an AM1.5 direct spectrum.

Towards commercialization of concentrator multijunction photovoltaic modules
2008 33rd IEEE Photovoltaic Specialists Conference, 2008Concentrating photovoltaic (CPV) modules occupy the middle ground between conventional, flat-plate photovoltaics and concentrating solar power (CSP) technologies. CPV promises to deliver the best of both worlds: the highest efficiency of any photovoltaic system combined with the higher capacity factor and scale-up potential of dual-axis tracking ...

Bonded Multijunction Photovoltaics to Improve Efficiency and Performance
Asia Communications and Photonics Conference, 2012Sun emits approximately 3.8x10 26 Joules per second and it produces more energy than global population demand in an hour. However, converting solar energy to electric energy is not trivial due to two major limitations. First, solar energy is not power dense, only ~1000 Watt/m 2 .
