Triple-junction a-Si based solar cells, having a structure of SS/Ag/ZnO/n/n/b/a-SiGe-i/b/p/p/n/n/b/a-SiGei/b/p/p/n/n/a-Si-i/p/p/ITO, are fabricated at the University of Toledo using a multi-chamber, load-locked PECVD system. We studied the effect of heavily doped p and n layers deposited at the tunnel junction interfaces between the top and middle component cells and between the middle and bott...
Temperature rising is a negative factor in almost all systems. It could cause by self heating or ambient temperature. In solar photovoltaic cells this temperature rising affects on the behavior of cells. The ability of a PV module to withstand the effects of periodic hot-spot heating that occurs when cells are operated under reverse biased conditions is closely related to the properties of the ...
Summary Multijunction solar cell design is guided by both the theoretical optimal bandgap combination as well realistic limitations to materials with these bandgaps. For instance, triple-junction III-V multijunction cells commonly use GaAs a middle because of its near-perfect material quality, despite being higher than for global spectrum. Here, we modify using thick GaInAs/GaAsP strai...
Colloidal quantum dot solids combine convenient solution-processing with quantum size effect tuning, offering avenues to high-efficiency multijunction cells based on a single materials synthesis and processing platform. The highest-performing colloidal quantum dot rectifying devices reported to date have relied on a junction between a quantum-tuned absorber and a bulk material (e.g., TiO(2)); h...
DOI: 10.1002/aenm.201700345 conversion efficiency. Devices comprising these alloys (and, in some cases, the group IV element, germanium) have held the world record for conversion efficiency under concentrated sunlight for more than the last thirty years with steady increases in efficiency year-on-year.[2] Efficiency improvements result from many aspects of MJSC design, but among the most import...
the steady state effect of vertical fins is assessed on a photovoltaic/thermal solar air heater having a double pass configuration in which fins are placed in the lower channel perpendicular to the direction ofair flow. air passes through the upper channel of the air heater and before passing in the opposite direction through the lower channel. the effects of design, climatic and operating para...
