Fig. 1.17 Structures of organic tandem cells. a Two heterojunction cells connected together. b A
series of many extremely thin heterojunction cells with identical absorption spectra. c Transparent
connection layers with optimum thicknesses. d Two blended layers absorbing light from different
parts of the spectrum
