The absorption coefficient of single-crystal silicon is very important for applications in semiconductor processing and solar cells. However, large discrepancies exist in the literature about the absorption coefficient of silicon, especially in the visible and near-infrared region.
In this paper we theoretically investigate the possibility of increasing both absorption coefficient and the efficiency of light absorption in silicon solar cell by creating the active layer as a particulate (disperse) layered structure (multilayer) consisting of monolayers of spherical silicon particles with size of the diffusion length order.
For silicon solar cells it is desirable to know the absorption coefficient over the range of 1.1–4.0 eV and over a wide range of temperature, particularly when evaluating the concentration type systems. An analytical (empirical) expression has been developed for this purpose.
The optical absorption coefficient is an important parameter in calculating the performance characteristics of solar cells. For silicon solar cells it is desirable to know the absorption coefficient over the range of 1.1–4.0 eV and over a wide range of temperature, particularly when evaluating the concentration type systems.
Integral absorption coefficient of layered structure of silicon particles reaches 0.9. Growing the large particles leads to growing the absorption coefficient. The size of silicon particles should be close to the diffusion length order. Design of solar cell based on particulate system of silicon particles is proposed. 1. Introduction
