Abstract

This research aims to improve the performance of a-Si: H solar cells, particularly in terms of carrier transport properties, through a numerical design approach utilizing AFORS-HET simulation software. By performing a series of rigorous computer simulations, we explore the potential regulation of the intrinsic layer thickness, carrier mobility, loading factor, and density of states (DoS) distribution in the solar cell's intrinsic layer. Recombination losses are reduced, and light absorption efficiency is significantly increased when the intrinsic layer thickness is adjusted, as shown by simulation findings. Moreover, reduction of transit times and enhancement of the total efficiency of the solar cells depend on increased carrier mobility. Parameters can be adjusted to attain optimal performance under various operating situations by adjusting the DoS and load factors. Furthermore, the simulations provide insightful information about the interactions between the junctions in solar cells with double junctions. Our results of this research provide an important contribution to efforts to develop more efficient and sustainable a-Si: H solar cells and emphasize the importance of numerical design approaches in photovoltaic technology.

Abstract

Heavy metal pollution is still a serious problem today. One method that can be used to remove heavy metal content from water is the adsorption method. In the adsorption method, the choice of adsorbent is very important to optimize the adsorption process. One of the materials that can be used as an adsorbent is tea waste. Tea waste contains cellulose, which can be used to bind heavy metal ions. This research was conducted to synthesize adsorbents using tea waste and then test their ability to adsorb lead ions. The adsorbent synthesis process is divided into several stages, namely washing, drying, refining, soaking in HCl solution, and drying again. The results of the adsorption tests conducted found that the tea waste adsorbent could remove 99% of the lead metal ion content in the water. The conclusion from these results is that the synthesis process has succeeded in making tea waste adsorbent that can adsorb lead ions in water.
