An expression for collection efficiency in actual Si solar cells is derived from the expression of Basore for inverse quantum efficiency vs. absorption depth at near-bandgap wavelengths. In the new expression, only internal rear-surface reflectance is an adjustable parameter. The new expression is used in reported actual Si solar cells, where it is compared to different approaches to evaluate collection efficiency including the linear fitting to inverse internal quantum efficiency versus absorption depth. This allows showing experimentally that these approaches are more liable to errors than the proposed expression for collection efficiency. © 2018 Author(s).
