The weak light trapping in the active layer of thin film solar cells is a major issue in solar cell technology. Periodic grating is one of the methods used to improve light absorption in the thin film solar cell's substrate. The current study presents the effect of a 1-D triangular grating device on solar cell absorption enhancement.
A thin film solar cell is considered a means of reducing material utilization and efficiency in order to reduce solar energy expenditures. The major problem with solar cell technology is the weak trapping of the thin film solar cell's active layer of light.
Plasmonics is an excellent new way to increase the absorption of light in thin film solar cells. Some methods are used to improve the absorption of light from the substrate of the thin film solar cell, i.e., periodic grating.
However, Triangular grating produces a sharper resonance peak than other grating profiles (Catchpole and Polman 2008 ). Silicon is widely used as the primary component of solar cells. It is abundant on the planet. It's also a nontoxic and low-cost material. The thickness of amorphous silicon is critical to the efficiency of a solar cell.
To optimize the parameter for thin-film solar cell production, we used a parametric analysis.
It was discovered that thin silver film provides improved sunlight reflection and appropriate silver film angles for agitation of SPPs, half of the intensity of SPPs sheds onto the substrate (c-Si), and also achieves higher surface plasmon polaritons propagation length.
