Optical analysis of haze ratio and antireflection in structured thin film solar cell

In this paper, the influence of the haze ratio and antireflection properties of the thin film solar cell with a periodic texture is theoretical investigated. Two different cases, Case 1 and Case 2, are compared. Case 1 shows an extremely high haze ratio of 97.4% while Case 2 shows a low reflectance of 0.3%. For the thickness of the a-Si:H layer is 100nm~400nm, the J
_SC
of the antireflection case is higher than that of high haze ratio one. Until the thickness of the a-Si:H layer is increased to 500nm, the J
_SC
of Case 1 is 20.5 mA/cm
²
which is higher than Case 2.
