Abstract :
A practical design has been developed for string-type PV receivers intended to operate in space application line-focus concentrator modules. MOCVD grown AlGaAs/GaAs solar cells are used in these receivers as the main elements whereas Zn-diffused GaSb solar cells are used in tandem to improve total efficiency. Secondary cylindrical lenses operating similar to a “large scale prismatic cover” and transforming a focal light line into separated spots are introduced on the surfaces of solar cells. Efficiency 18.3% (AM0, 15 Suns, RT) has been measured on the receiver 72 mm long constructed from twelve series-connected AlGaAs/GaAs solar cells
