Thin-film Si solar cell technology is a promising photovoltaic (PV) technology for delivering low-cost solar electricity. A drawback of this technology is a relatively low stabilized efficiency of modules that varies between 5 to 10%. Light management plays a crucial role in incr

Diffusive dielectric materials such as white paint have been demonstrated as effective back reflectors in the photovoltaic technology. In this work, a one-dimensional (1D) optical modeling approach for simulation of white paint films is developed and implemented in a 1D optical s

In this work, we investigate the concept of transparent conductive oxide (TCO)/white paint (WP) back reflectors as an alternative to the conventional textured metal-based reflectors in thin-film silicon solar cells. The optical characterisation results show that WP back reflector

In thin-film silicon photovoltaic technology light management is important for achieving high efficiency of solar cells. Advanced light trapping techniques have to be employed to boost the solar cell efficiencies further. In this contribution we investigate the following advanced

Optical analysis of hydrogenated amorphous silicon (a-Si:H) solar cells with a periodic texture applied to the interfaces was carried out by two-dimensional optical simulator. The optical simulator solves the electromagnetic wave equations by means of finite element method using

A concept of a modulated one-dimensional photonic-crystal (PC) structure is introduced as a back reflector for thin-film solar cells. The structure comprises two PC parts, each consisting of layers of different thicknesses. Using layers of amorphous silicon and amorphous silicon
