Journal ArticleDOI
Disorder and the Optical-Absorption Edge of Hydrogenated Amorphous Silicon
TL;DR: The effect of thermal and structural disorder on the electronic structure of hydrogenated amorphous silicon is investigated by measurement of the shape of the optical absorption edge as a function of temperature and thermal evolution of hydrogen as discussed by the authors.
Journal ArticleDOI
Intensity enhancement in textured optical sheets for solar cells
TL;DR: In this article, the authors adopt a statistical mechanical approach toward the optics of textured and inhomogeneous optical sheets and show that the local light intensity in such a medium will tend to be 2 n−2−x times greater than the externally incident light intensity, where n is the local index of refraction in the sheet.
Journal ArticleDOI
Limiting efficiency of silicon solar cells
TL;DR: The detailed balance method for calculating the radiative recombination limit to the performance of solar cells has been extended to include free carrier absorption and Auger recombination in addition to radiative losses.
Journal ArticleDOI
Optical characterization of amorphous silicon hydride films
TL;DR: In this paper, the optical properties of thin a-SiHx films were studied and the intrinsic optical limitations on the performance of the SiHx cells were defined for the absorption range 10−1-106 cm−1.
Journal ArticleDOI
Optical reflectance and transmission of a textured surface
TL;DR: In this paper, the effects of texture on reflectivity and transmission through an exact calculation of a boundary layer whose complex dielectric constant is an appropriate average of the material and air was obtained.
