宇宙用両面発電マイクロコンセントレーター
Abstract:
The key criteria for solar photovoltaic (PV) power in space are distinct from terrestrial applications. Ultra-compactness, maximal specific power (kW/kg and kW/m3), liberal optical tolerance, ease of fabrication, adequate heat rejection, and resilience under cosmic radiation are paramount. These considerations prompted the development of PV micro-concentrators. Here, we present and evaluate new ultra-compact, high-performance micro-concentrators for bifacial cells, in particular perovskites, which can attain concentration levels of tens of suns at the relatively large optical tolerances required in space. These designs can be tailored to a desired balance of concentration between the two sides of the bifacial cell.

01:26Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
