Currently single crystal silicon (Si) solar cell exhibits a conversion efficiency of about 25% and has dominated the solar cell market. However, due to low light absorption and indirect bandgap features, single crystal Si layers of around 200–250 µm in thickness are usually needed to efficiently harvest the sunlight.
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.
Ross and Hsiao reported that the efficiency cannot exceed 29% based on an ideal theoretical analysis, where entropy and unavoidable irreversibility place a limit on the efficiency of photochemical solar energy conversion.

This great development in the efficiency is not matched if the cost of the device is considered. The highly efficient PVs (mainly multi-junction solar cells) are prohibitively expensive , . On the other hand, the efficiency of the most dominant technology in the market (i.e. Si) is 25% in the lab and less than 20% commercially.
The maximum possible room-temperature power conversion efficiency of a single junction, c – Si solar cell under 1–sun illumination, according to the laws of thermodynamics, is 32.33% 6. This limit is based on the assumptions of perfect solar absorption and no losses due to non-radiative charge-carrier recombination.
