[IEEE 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Chicago, IL, USA (2019.6.16-2019.6.21)] 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Micro-Prism Spectrum Splitting Optics for Lateral-Arrayed Multi Junction Micro CPV
摘要： A micro-prism-array based low-profile spectrum splitting optics assembly is demonstrated. The precisely-controlled physical profile via low-cost plastic molding contributes to high optical transmission. The conjugate prism design and material matching design allow efficient spectrum splitting while introducing minimal beam deflection. This optics provides a cost-effective module assembly enabling high performance, lateral-arrayed multi-junction micro CPV modules.

AIP Conference Proceedings [AIP Publishing 15th International Conference on Concentrator Photovoltaic Systems (CPV-15) - Fes, Morocco (25–27 March 2019)] 15th International Conference on Concentrator Photovoltaic Systems (CPV-15) - Why and how does car-roof PV create 50 GW/year of new installations? Also, why is a static CPV suitable to this application?
摘要： With this car-roof PV, 70 % of passenger’s may be able to run by solar energy. The potential of the market size is 50 GW/year. However, it is not an easy task to meet the requirement of the main component of EV and the creation of the massive market. It is also apparent that the market will be small as far as we only try to apply the conventional crystalline Si cells. The CPV technology with high power conversion efficiency and capable of coloring and covering on the three-dimensional curved surface is suitable for this market. The static CPV is useful for this application with a better collection of diffused sunlight. One of the problems is the spectrum mismatching. However, this issue is easily solved by adjustment of the bandgap of the bottom cell.

Effect of the Irradiation on Optical and Electrical Properties of Triple-Junction Flexible Thin Solar Cells for Space Applications
摘要： The most common multi-junction solar cell arrangement employs the InGaP/InGaAs/Ge configuration, which is usually exploited for high-efficiency space applications. We here test the reliability of a triple-junction device with an innovative low-thickness and flexible configuration: this is investigation is aimed at providing its main macroscopic features which must be taken into account for their applications. Notably, the specific optical and electrical features and the performance variation of these thin solar cells are systematically analyzed, both in begin-of-life (BOL) configuration and after irradiation (end-of-life, EOL) by either electrons or protons. Measurements of I – V curves, with correlated parameters, and of spectral responses (external quantum efficiency) are accomplished on several BOL and EOL samples: this allows to describe the inhomogeneous damage of the subjunctions and to follow the evolution of the solar cell physical quantities as a function of the kind and the amount of irradiation. Finally, photoluminescence emission spectra are measured, pointing out the effect of particle bombardment on luminescent features. Our results show that these innovative solar devices allow for the combination of high specific power, mechanical flexibility, high performance, and strong resistance to particle irradiation, making them an excellent option for space applications.
