Abstract

The counter electrode (CE) in dye-sensitized solar cells (DSSCs) has an essential impact on the photovoltaic performance and long-term stability of DSSCs. Carbon materials, such as activated carbon (AC) and graphene, are attractive candidates for CE materials in DSSCs due to their low cost, high thermal conductivity, and high specific surface area. In this work, the manufacture of carbon CE using the knife coating method. Then, its performance was tested using a solar simulator and electrochemical impedance spectroscopy (EIS) testing. The samples with carbon and graphene counter electrodes show efficiencies of 0.29% and 0.23%, respectively. The findings revealed that the CE-based carbon materials had a significant impact on the performance of DSSCs. The proposed carbon materials, having low-cost fabrication, high conductivity, high thermal stability, and good corrosion resistance to electrolytes, may offer a promising solution for solar cell applications.

Abstract

The Gurah Beach Special Purpose Forest Area (KHDTK) in Blitar Regency is one of the conservation areas that plays an important role in maintaining the balance of the coastal ecosystem and environmental sustainability. However, increased tourism activity, climate change, and pollution could potentially lower air and environmental quality in the surrounding area. Additionally, there is no monitoring system yet that can provide real-time data information to support conservation decision-making. Therefore, a technological solution is needed in the form of a solar panel-powered IoT microcontroller-based weather and air quality monitoring station that can continuously measure environmental parameters such as temperature, humidity, rainfall, solar radiation, pollution levels, and fine particulate concentration to maintain the KHDTK environmental health index. This technology can provide accurate data continuously with remote monitoring integrated into a website for easy access, analysis, and decision-making. The methods used include site observation, design and assembly of the equipment, system installation, training, monitoring, and implementation, handover of goods, evaluation, and reporting. The results demonstrate that the system operates reliably, continuously generating accurate data for environmental quality assessment. The implementation of this technology can support sustainable conservation management efforts and contribute to the preservation of the KHDTK Gurah ecosystem.
