According to the Shockley-Queisser limits, the maximum theoretical solar cell efficiency was calculated by William Shockley and Hans-Joachim Queisser in 1961 using a primitive single p-n junction. The theoretical limit was found to be around 33%. This means that on a sunny day, a silicon solar cell with one p-n junction could theoretically collect up to 33% of the sun's rays.
The theoretical limit is far beyond that of the solar cells and many analyses show that the limit is just above 80% , , , (this is far beyond solar cell limits). The area is rich and many device designs and materials have been explored. However, the reported efficiencies are still small , . 3.
Some thorough theoretical analyses with more restricted practical assumptions indicated that the limit is not far above the obtained efficiency . Currently, we are in the midst of the third generation solar cell stage.
Each solar cell will have a fundamental efficiency limit depending on its band gap. The maximum efficiency limit for single-junction solar cells is about ~33.7% at E g ~1.34 eV (also called the optimum bandgap value for solar cells). The SQ limit values for single-junction solar cells have been documented in tabular form by Rühle et al.
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.
The performance limit of solar cell is calculated either by thermodynamics or by detailed balance approaches. Regardless of the conversion mechanism in solar cells, an upper efficiency limit has been evaluated by considering only the balances for energy and entropy flux rates.
