Monocrystalline silicon photovoltaic cell parameters

What are the design constraints for silicon solar cells?

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.

How thick is a silicon 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.

What is a silicon solar cell?

Basic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.

Does surface etching affect crystalline silicon solar cells?

Kim et al. (2013) reported the effect of surface texturing process on the crystalline silicon solar cells using saw-damage etching and concluded that there was no difference between the morphologies and reflectance for each surface condition after one hour of texturing process.

Is linear interpolation based on current–voltage characteristics of solar cells?

Tsuno et al. (2005) investigated the dependence of temperature and irradiance on current–voltage characteristics of different solar cells using linear interpolation method and observed that the physical validity of the linear interpolation for the temperature was based on the current–voltage characteristics of the p–n junction devices.

Which P-V characteristics are observed with multiple MPP?

However, complex P–V characteristics are observed with multiple MPP when the shade cell reaches 50 %. Fig. 7. PV Characteristics of the partial shading for one cell to 20 %. Fig. 8. P-V characteristics of the partial shading for one cell to 30 %. Fig. 9. P-V characteristics of the partial shading for one cell to 50 %. Fig. 10.
