Research on dye sensitized solar cells (DSSCs)


Dye-sensitized solar cell (DSSC) has attracted considerable interest since its first discovery, as it combines both the promise of high efficiency and low fabrication cost. DSSC can also be fabricated over flexible substrates and offer transparency and workability to be integrated into buildings as smart windows. Our research goal is to develop methods to fabricate high efficiency DSSCs using industrial-friendly process that allows further up-scaling and commercialization. Another main goal is to improve the long-term performance of DSSCs and integrate them into various electronic system

Current related project:

1. Materials and device engineering of monolithic dye-sensitized solar cells. Interconnected dye-sensitized solar module with monolithic structure offer a promising concept with the benefit of low material cost and ease in fabrication as opposed to the conventional sandwich-type configuration. Monolithic DSSCs offers more affordable platform because the monolithic configuration only requires one conducting substrate. Monolithic DSSC also requires easier manufacturing processes compared to DSSC with sandwich structure because all layers can be deposited straightforward using screen printing technology. Monolithic structures also provide a significant advantage in the manufacture of large DSSC modules because there is no need to unite two substrates that require a high degree of precision. This project focuses on the development of carbon and polymer-based materials as counter electrode in monolithic DSSC, and the scale up fabrication of monolithic DSSC into grid-type module.

2. Photoelectrode doping for DSSC (Master student, collaboration with Metallurgical Engineering Department, Institut Teknologi Bandung, ITB). In this project, we are investigating the effect of Sn, Zn, and C doping on anatase-based TiO2 photoelectrodes on the efficiency of dye-sensitized solar cells (DSSC).

3. Carbon-based electrodes for monolithic DSSC and PSC (Undergraduate student, collaboration with UIN Sunan Gunung Djati Bandung). In this project, we are optimizing the synthesis of carbon-based composite materials and their application as counter electrode in DSSC and back contact in PSC
