Material dan Divais Sel Surya

The Materials and Devices for Solar Cells or Material dan Divais untuk Sel Surya (MDSS) group is part of research groups within the Research Center for Electronics and Telecommunications, Indonesian Institute of Science (P2ET LIPI).

Our group is inspired to develop technology to address the pressing need of sustainable, yet green and clean energy resources for humanity. Our research is primarily focused on the development of materials syntheses and device fabrications for solar energy driven applications. We are currently developing novel ways to build and improve the performance stability of dye-sensitized solar modules. Moreover, we are also investigating new materials and methods to develop polymer- and perovskite-based solar cells. Our main competencies can be seen in the Figure below:

Current Main Research:

Development of carbon nanotube as perovskite solar cells electrode for electric vehicle application (Funding from PRN LPDP)

Typical material used as an electrode in perovskite solar cells is a noble metal such as gold or silver. Carbon material such as carbon nanotube (CNT) has the potential to replace noble metal due to its decent conductivity, stability, high surface area, and lower cost. CNT also has a suitable work function to obtain high open-circuit voltage. Therefore, we apply CNT as a top contact of perovskite solar cells and module in this project. The project is divided into five stages which are planned for five years. In brief, the project will start from the preparation of the CNT layer, application of CNT layers as perovskite-based solar cell electrodes, stability of perovskite cells monitoring, scale-up, and solar module prototyping, which then will be applied to a charging system for electric cars.
