Abstract

It has been successfully investigated the utilization of waste plastic bottles as a solar water distiller for the provision of clean water. In this study 600 and 1500 mL plastic bottles used for solar water distiller with 9 variations. A 600 mL bottle with a variation of the addition of soda cans painted black or not (3 variations) as type A. Hereinafter, 600 mL plastic bottle connected with 1500 mL plastic bottle positioned above 600 mL bottle contained small plastic bottle placed in bottle 1500 mL with variations of either painted black or not (3 variations) is called type B. Moreover, the next three variations are 1500 mL bottles cut in half to resemble open containers with smaller plastic bottles placed inside whether painted black or not (Type C). Furthermore, as a comparison of plastic containers (basin) with a diameter of 25 cm used for the solar distiller. The study was conducted with 30 mL of seawater as the initial data, after 8 hours exposed to the sunlight. The results showed that plastic containers had better efficiency compared to all types of the plastic bottle as solar distiller with the value up to (55.7 ± 3.1)%, while for the distillation system with plastic bottles, the highest efficiency was obtained type distillation system A with a range of 11-13%. While for type B and C respectively equal to 1-4%.

Abstract

Hydrogenated amorphous silicon (a-Si:H) is one of the most promising solar cell materials, as compared to the crystalline silicon (c-Si). This material has a greater absorption with less material requirement (thin). So it is expected to reduce the cost of production and price of solar cells. But until now there are still many unresolved issues, especially with regard to low efficiency, and the Staebler-Wronski effect. This study aims to describe the effect of Staebler-Wronski, which is the effect of long-time exposure to heat on the layer of solar cell material by means of annealing treatment. The results show that the longer annealing time, there is a tendency to decrease transmittance, which is thought to be caused by changes in crystallinity, energy band gap, Urbach energy and particle size. The increasing annealing time can lead to the release of hydrogen bonds that cause an increase in localized state, due to the activation of the dangling bond which is the main cause of the Staebler-Wronski effect.
