Solar cells convert sunlight into electricity via the photovoltaic effect. The photovoltaic (PV) effect was first reported in 1839 by Becquerel when he observed a light-dependent voltage between electrodes immersed in an electrolyte. However, nearly a century later in 1941, the effect was reported in silicon. In 1954, the first working solar cell module was announced. The

Turning to the results, the conversion efficiency of c-Si solar cells has a maximum at a given value of the thickness, which is in the range 10–80 µm for typical parameters of non-wafer-based silicon.
Improving the efficiency of silicon-based solar cells beyond the 29% limit requires the use of tandem structures, which potentially have a much higher (~40%) efficiency limit. Both perovskite/silicon and III-V/silicon multijunctions are of great interest in this respect.
By direct numerical solution of Maxwell’s equations and the semiconductor drift-diffusion equations, we demonstrate solar-power conversion efficiencies in the 29%–30% range in crystalline-silicon photonic-crystal solar cells.
According to these approaches (usually referred to as semi-empirical), the efficiency of a solar cell depends on the optical bandgap (E gap) of the semiconductor material indicating that, for crystalline Si (E gap ∼1.1 eV), the maximum efficiency stays in the ∼ 15–22 % range.
