Our experiments reveal that both degradation stages can be fitted using a sum of two exponential decay functions. The resulting degradation rate constants depend both on the temperature and the light intensity applied during degradation. For the fast component, we determine an activation energy of (...
Space-based solar power, the collection in space of solar energy, which is then transmitted as a microwave or laser beam to the ground and converted into electrical energy. The idea of space-based solar power predates the space age. Konstantin Tsiolkovsk
It can simultaneously unveil the mass‒energy transfer mechanisms in SWE devices and assess the SMDW yield potential of the SWE technique both technically and economically. The physical model is based on pilot experiments under natural environmental conditions to clarify the principle of designing the...
and L.H. conceived the experiments, performed data analysis and wrote the paper. Z.S. led the fabrication of the solar cells. Y.S. and X.L. helped with the sample preparation for characterization. Y.W., Y.Y. and Y.Z. participated the discussion about the feasibility of the experiment...

Space Agency astronaut Christer Fuglesang continued construction on the International Space Station (ISS). Below them lie New Zealand and Cook Strait in the Pacific Ocean.The ISS must be maintained and repaired regularlyso that its inhabitants can complete missions and experiments through at least ...
First experiments to reduce absorber thickness were already performed 20 years ago [153]. Various light management techniques have been used to improve the absorption in thin Cu(In,Ga)Se2 layers, including plasmonic structures and improved back reflectors, see e.g., refs. [154-159]. With ...

To date, experiments have most often been conducted in laboratory conditions in the absence of moisture and oxygen such as inert atmosphere. These processes and systems are expensive to perform because they relate to commercialization conditions that demand high stability with the additive-free hole ...
X.R. designed the experiments and fabricated the solar cells. M.Y. guided the experimental fabrication technology. Y.Z. was responsible for the flexibility simulation and measurement, figures, tables and preparation for publication. S.Y. and C.H. developed the TCO process. F.P. developed the...
