Organic and hybrid perovskite based solar cells have a huge potential to significantly contribute to a clean electricity supply of the future. However, so far they exhibit complex and hierarchical degradation paths and their understanding can only be acquired through the application of complementary chemical and physical characterization techniques. This limited device stability is the main hurdle...
Dye a sensitized solar cell (DSSC) is expected to be a potential leader in the technology of solar cells in the future. The low-cost manufacturing of this technology offers an alternative to the silicon-based solar cells. Realizing the low efficiency and rapid degradation of DSSCs, researchers are lead to analyze the factors to maintain its stability. In this paper, DSSC was fabricated by using natural...
Degradation in the performance of TiO2 based dye sensitized solar cells was studied by electrochemical impedance (EIS) and Fourier transform infrared (FTIR) spectroscopy. Degradation was carried out by aging the dye-sensitized solar cells in ambient conditions for 4500 hours. The current-voltage performance results, measured under solar simulator light show a 88% reduction in the short circuit current...
Quasi-mono (mono-like) is a well-known process for ingot growth that has potential to significantly increase cell performance over traditional multi-crystalline based silicon solar cells. In general, ingot is divided into A, B, C area. In this presentation, cells made from A and B areas average efficiency are comparable to traditional multi-crystalline cell made from DSS method by acid-texturing process...
In this work, we study the reliability of sensitized solar cells. The reliability study is carried out using accelerated optical and pure thermal stresses with the purpose to extract a degradation law as a function of accelerated parameter and to understand which is the mechanisms involved in the degradation. The responsible of the degradation during thermal or illumination stress is the formation...
In this work, a prototype of dye-sensitized solar cell using organic dye from blackberry and semiconductor TiO2 nanocrystals was studied. The cell was fabricated using materials locally obtained in Indonesia (except the transparent conducting oxide glass), and using technologies available in-house in laboratories in University of Pelita Harapan. The cell was tested in an own-constructed dark box by...
