Maximum power conversion efficiency 14.7% is obtained when junction depth is 0.7 μm and device thickness is 90 μm, Variation of ideality factor shows recombination limited current is dominating for the deep junction solar cells. Short circuit current density (J SC ) reduces as junction depth increases which improve V OC of the solar cell.
However, silicon's abundance, and its domination of the semiconductor manufacturing industry has made it difficult for other materials to compete. An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick.

For silicon solar cells, the basic design constraints on surface reflection, carrier collection, recombination and parasitic resistances result in an optimum device of about 25% theoretical efficiency. A schematic of such an optimum device using a traditional geometry is shown below.
Due to the series connection of each sub-cell, the device output photocurrent will be the minimum of the potential current from each sub-cell, modifying Eq.
The operation of a crystalline silicon solar cell was studied by a methodology based on collection efficiency. The quantum efficiencies of the base, emitter, and depletion layers were determined separately using numerical solutions. The collection efficiency was then determined by the reciprocity theorem.
