Microstructured antireflective encapsulant on concentrator solar cells
نویسندگان
چکیده
Microstructured antireflective coatings (ARCs) can reduce reflection losses over a wide range of incidence angles when applied to the surface high-efficiency III-V photovoltaic cell in concentrator (CPV) system. In this article, we present microstructured ARC consisting monolayer close-packed silica microbeads partially submerged within polydimethylsiloxane (PDMS) encapsulant for use reference 500× CPV submodule. Comparing commercialized SiOx coating with 25% 1,000 nm-diameter beads, angle-dependent external quantum efficiency measurements yield 2.6% current gain coating. Simulations demonstrate good agreement measurements, predicting 2.4% same configuration. Extrapolating our validated model, estimate maximum and achievable (within large manufacturing tolerance) 3.4% 2.9 ± 0.4% using 60% 10%–32% 760 respectively.

Reliability of III-V concentrator solar cells
III-V concentrator solar cells are starting to be commercialized. However, no complete studies about their reliability have been carried out. A review about both the accelerated ageing tests and real time tests developed till now is presented. A proposal about the required tests is also done. In this stage, the tests show that III-V concentrator cells are robust devices with MTTFs well over the...
متن کاملNovel accelerated testing method for III-V concentrator solar cells
Accelerated testing is a necessary tool in order to demonstrate the reliability of concentration photovoltaic solar cells, devices which is expected to be working not less than 25 years. Many problems arise when implementing high temperature accelerated testing in this kind of solar cells, because the high light irradiation level, at which they work, is very difficult to achieve inside a climat...
متن کاملPlanar micro-optic solar concentrator.
We present a new approach to solar concentration where sunlight collected by each lens in a two-dimensional lens array is coupled into a shared, planar waveguide using localized features placed at each lens focus. This geometry yields a thin, flat profile for moderate concentration systems which may be fabricated by low-cost roll manufacture. We provide analyses of tradeoffs and show optimized ...
متن کاملFast Acquisition of the Characteristics of Silicon Concentrator Solar Cells
The characterisation of 85 rear-line-contacted silicon concentrator solar cells on one single wafer requires a fast, automated measurement system. In this paper an easy to use needle array measurement system is presented, which allows an automated sequential measurement of dark and light IV curves of all cells on one wafer. For acquiring IV curves under high illumination levels (up to 500 suns)...
متن کاملReliability evaluation of III-V Concentrator solar cells
Concentrator solar cells have been proposed as an interesting way of reducing the cost of photovoltaic electricity. However, in order to compete with conventional solar modules it is necessary not only to reduce costs but also to evaluate and increase the present reliability. Concentrator solar cells work at higher temperature, solar radiation and current stress than conventional solar cells an...
