Customer ServiceIn general, an increase in absorber thickness can result in higher values for two key parameters of the solar cell: short-circuit current and open-circuit voltage. This increase is attributed to the greater absorption of solar light by the solar cell, leading to a higher generation of charge carriers.
The thickness of solar cells should be less than the diffusion length of the induced carriers. To avoid the unnecessary resistance and to reduce the production cost thickness should be equal or less than the width of the depletion region. Much smaller thickness produces weak static electric fields in the depletion region.
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.
It is well known that typical Si solar cells are rather thick (hundreds of micrometers). Now, Si has an indirect band-gap and therefore weak optical absorption at low energies (needing a phonon-assisted process to absorb a photon with energy below the direct gap), and this is sometimes presented ( 1, 2) as the reason for that large thickness.
A P-type solar cell is manufactured by using a positively doped (P-type) bulk c-Si region, with a doping density of 10 16 cm -3 and a thickness of 200μm. The emitter layer for the cell is negatively doped (N-type), featuring a doping density of 10 19 cm -3 and a thickness of 0.5μm.
Specifically, it is observed that Voc and FF decrease as the thickness increases, primarily due to the rise in series resistance. In general, an increase in absorber thickness can result in higher values for two key parameters of the solar cell: short-circuit current and open-circuit voltage.
