Solar energy converter simultaneously gaining electrical and thermal power - uses successive heat sinks distributed to suit energy band levels

摘要

A solar energy conversion system has mirrors (2,3) that select different solar energy spectra. Low band energy is selected by a first stage (4) with successive stages handling medium and high band energy levels (5,6). Each stage has a heat sink (7,8,9) so that the temp. of a fluid reduces (T1,T2,T3). An alternative version has a tandem solar cell arrangement in which stages are stacked with input from a common cell. A further version has different band energy stages arranged in sequence on a pipe.
