“…We have already shown that, when the bandgap is one of the simulation parameters, optimizing Eq. (19) can lead to designs with high values of J Opt SC but low values of extractable electrical power [8]. A better approach is to complement the photonic step by the electronic step, as accomplished in Section 3.…”

A design tool was formulated for optimizing the efficiency of inorganic, thin-film, photovoltaic solar cells. The solar cell can have multiple semiconductor layers in addition to antireflection coatings, passivation layers, and buffer layers. The solar cell is backed by a metallic grating which is periodic along a fixed direction. The rigorous coupled-wave approach is used to calculate the electron-hole-pair generation rate. The hybridizable discontinuous Galerkin method is used to solve the drift-diffusion equations that govern charge-carrier transport in the semiconductor layers. The chief output is the solar-cell efficiency which is maximized using the differential evolution algorithm to determine the optimal dimensions and bandgaps of the semiconductor layers.

“…Later, Anderson et al [17] used the RCWA for the photonic step and the standard FEM for the electronic step for simulating the same Schottky-barrier thin-film solar cell (which is not considered in this paper). Other researchers have also developed techniques for optoelectronic simulation [18,19,20].…”
