Efficient Light Harvesting in the Nanotextured Thin Film Solar Cells
2021
Nanostructures have a great role for boosting the efficiency of the photovoltaic devices by trapping the light beams and increasing the absorption as well as carrier collection. This chapter summarizes the most recent light management approaches in the thin film solar cells. First, the effects of various nanostructures in terms of geometry, pitch size, and aspect ratio on the optoelectronics properties of devices are discussed in detail. Later, the applications of the nanostructures as anti-reflection layers and device substrates in the solar cells are explained. Then, their advantages and possible mechanisms are discussed to have a better understanding from the nanostructured-based devices. Additionally, the issues induced by nanostructures and the possible solutions for addressing these shortenings are proposed in this chapter.
