Cooling photovoltaic (PV) cells during concentrated solar radiation in specified arrangement in coolant with as low electric conductivity as possible

摘要

The PV cells are immersed in a liquid coolant, which is operated in its boiling range. The PV cells are so arranged that gas bubbles, rising from one side of a PV cell, pass at the rear side of a PV cell located above it.The liquid coolant is circulated mechanically, or by the mamut effect. Parts of the PV cells may be electrically insulated.
