Research on Perovskite Solar Cells (PSCs)
Perovskite solar cells (PSCs) have shown remarkable progress in recent years with rapid increases in conversion efficiency. While the technology has become highly efficient in a very short time, a number of challenges remain before they can become a competitive commercial technology such as stability issue. Our current research on PSCs is directed toward scale-up using blade coating and printing as processing method.

1. 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 modules 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-based solar cells monitoring, scale-up, and solar module prototyping, which then will be applied to a charging system for electric cars.

2. Development of third generation solar cell using doped copper thiocyanate hole transport layer for electric vehicle application (Internal funding from LIPI, PN project). Third-generation solar cells based on organic and perovskite materials is a new photovoltaic technology employing low-cost thin film, which is more suitable for electric vehicle integration. The choice of hole/electron transport layer is an important aspect determining the efficiency and stability of this solar cell technology. Copper thiocyanate (CuSCN) has been used as hole transport material (HTM) for third-generation solar cells due to its highly transparent, stable, low cost, and easily processed. However, the CuSCN's low conductivity is often limiting its potential. In this project, we will add inorganic salt materials as a dopant for CuSCN to enhance its conductivity. To improve their performance and stability, the doped CuSCN will be applied as HTM of organic and perovskite solar cells. This activity aims to support the theme of national electric vehicle development.
3. Study of the effect of defect states on photovoltaic properties of perovskite solar cells (PhD student, collaboration with Physics Department, Institut Teknologi Bandung , ITB). In this project, we examine the use of additives for reducing crystal defects in perovskite absorber layer and analyze its effect on the solar cell performance.
4. Optical properties study of perovskite materials using ellipsometry spectroscopy (PhD student, collaboration with Physics Department, Universitas Gajah Mada, UGM). In this activity, we study the optical properties of graphene oxide/MAPbI3 based on ellipsometry spectroscopy and its application for perovskite solar cells
