I wonder if the solar panels has been coated with a transparent material that is metallic-like and conductive (or some degree of it) and so prevent localized charging.

Typically this is ITO (indium tin oxide). This is usually used in the panel electrodes.

However this is a thin layer on the wafer and is usually covered by thick glass or plastic encapsulation which is very insulating. So you'd need another ITO layer on the encapsulated surface before you put down the anti dust surface.

A briefing and progress report on the engines, parts, structures, and technologies used on the superheavy Long March 9 (CZ-9) carrier rocket, including the 500-ton liquid oxygen kerosene high-pressure supplementary combustion engine, the 220-ton supplementary combustion cycle hydrogen-oxygen engine, the 25-ton expansion cycle hydrogen-oxygen engine, and the design of the force bearing structures of the rocket body.

I have no time to translate these, not to mention they are beyond my limited Chinese. Please feel free to take a crack at it.

Dickinson said China had made “amazing” strides in space, with 500 satellites in orbit compared with 100 just five years ago. Beijing also revealed a new capability in January when a Shijian-21 satellite moved away from its regular orbit and dragged a broken communications satellite to what is known as a “graveyard” orbit. Dickinson said the SJ-21 had dual-use military-civilian capabilities — potentially to remove adversaries’ satellites from orbit.
