Advanced Industrial Tunnel Oxide Passivated Contact Solar Cell …
In this study, we propose an advanced tunnel oxide passivated contact (TOPCon) solar cell structure for bifacial usage. The proposed structure, named advanced industrial TOPCon (Ai-TOPCon), adopts rear-side local carrier-selective contacts to avoid rear-side light-absorption loss. Ai-TOPCon features larger rear-side light currents and improves the …

General pool, section G3B
Attenuation or absorption of radio signal is lowest at the frequency just below the Maximum Usable Frequency (MUF). The maximum usable frequency is the highest frequency you can use at a specific time and location which will still allow your signal to be reflected back to earth, rather than continuing into outer space!
Anyone have any idea what the "solar attenuation servos" are
Yet, I have the book that this image came from, the TIE Fighter Owners'' Workshop Manual, and beyond the single reference in this image''s legend, there is no mention of servos or ''attenuation'' of the solar cells. Maybe this has something to do with pumping? But the servos do not appear to be connected to the solar accumulator lines.

Polycrystalline silicon thin-film solar cells: Status and perspectives
Matsuyama et al. from Sanyo Electric Co. could achieve impressive solar cell results by using solid phase crystallized thin silicon films on metal substrates [30], [31], [32].With an efficiency of 9.7% (active area) and an open-circuit voltage of 553 mV they could set a remarkable benchmark in the 1990s [31]..
Different Degradation Modes of PV Modules: An Overview
During solar cell manufacturing, various processes like wafer slicing, cell wafer manufacturing, stringing and embedding may create cracks in PV cells. Stringing process has the highest potential to cause cracks in the solar cell [58, 59]. During fabrication of solar cells, cracks mostly originate from three different sources : 1.
