Abstract

Renewable energy sources are intensively developed for substituting fossil energy by several routes, such as solar cells and wind power. As a kind of solar cell, dye-sensitized solar cell (DSSC) was studied for low cost and environmentally friendly cell in competing with a silicon-based cell which dominated in the market. But, main problem in DSSC is low current density and power conversion efficiency, especially zinc oxide (ZnO)-based DSSC. In this paper, we enhance the ZnO nanorod properties through the doping of aluminum (Al). For obtaining optimum results, we varied the dopant concentration of 1%, 1.5%, 1%, and 3%. The Al-doped ZnO nanorod was grown by a seed-mediated hydrothermal method at 90oC for 8 hours. The physical properties were analyzed by field emission scanning electron microscopy and EDX, while the photovoltaic properties were analyzed by J-V curve analysis. An improvement of photovoltaic performance up to 200% is obtained by the ZnO nanorod with 1% Al-doped concentration.

Abstract

The ecoprint coloring technique has been widely applied by people from various circles because it uses natural materials that are easy to obtain and do not pollute the environment. Ecoprint is one of the batik making activities through a process of transferring color and shape to fabric through direct contact to produce environmentally friendly products. The partners for this activity are students from the Puldama district, Yahukimo Regency who are studying in Sentani, Jayapura Regency. This Ecoprint training activity is motivated by the condition of partners who do not receive enough training so that they often spend time without any useful activities being carried out. This activity consists of two stages, namely preparation and implementation. The methods used are lectures and mentoring. The results that have been achieved are that participants have knowledge about how to create works of art in the form of printed motifs on fabric using the ecoprint technique, participants have the skills to print motifs on fabric using the ecoprint technique. Participants showed an enthusiastic attitude to continue these skills as an initial form of entrepreneurship.
