During the last few decades, crystalline silicon solar cells have undergone extensive scientific and technological developments with the highest conversion efficiency ( η) of 26.7% reported on 165 μm thick silicon substrate at a research level [ 9 ].
The current density in a tandem is, therefore, half that of a silicon solar cell. The voltage of the two-terminal tandem device is the sum of the voltages of the individual subcells. Given that the material placed on top of the silicon has a wider band gap, it can be expected to produce a higher voltage.
Introduction It has been shown [1–3] that, especially in solar cells made from multicrystalline silicon (mc-Si), short-circuit current density jsc can vary significantly across the cell and even limit local conversion efficiency Kxy .

Several factors explain the drive towards higher efficiency silicon solar cells. High-efficiency solar modules require less mounting hardware and space and result in a lower balance-of-system cost. Such modules also yield higher energy densities, which may be important for applications where space is at a premium.
In recent years, thanks to improved silicon ingot growth processes, defect engineering and contamination control during solar cell fabrication, the bulk electronic quality of crystalline silicon wafers has improved to such a point that further device advances now rely on innovative interface passivation and carrier-selective contact structures.
Molybdenum oxide has been proved to function as a highly efficient hole contact for both n-type and p-type silicon. 302,307–310 Such dopant-free contact concepts show great promise for silicon solar cells as a potential route to minimize Auger recombination in the carrier-selective regions.
