Numerical evaluation of the optical-splitter system efficiency using a TCO as optical splitter

In the present work, we simulate the J-V characteristic of a solar cell combination to evaluate the efficiency in an optical splitter system. Two different transparent conductive oxides (TCO) were used as splitters (ITO and SnO 2 :F). The spectral response of the TCOs was modeled according to Drude’s theory, using different concentration values. Then, the J-V characteristics of the cells were simulated by SCAPS 1D, using the spectra obtained for each TCO by superimposing the spectral response on the solar spectrum. The results indicate that solar cells can achieve efficiencies in the system above 17% using ITO as splitter whit a positive gain for both solar cells.
