ÖZET
The emerging thin-film solar cells have led to focus on low-cost and earth-abundant p- type semiconductor materials in order to achieve higher photovoltaic efficiency goal. Tin sulfide has been successfully applied to different semiconductor devices due to its excellent optoelectronic properties. Organic perovskite solar cells have been attracted in the short period of time and showed higher efficiency compared to other photo- absorber materials. The fabrication of emerging semiconductor photo-absorbers over the flexible substrates have been developing and these can be integrated for various applications.

In this talk, Dr. Ballipinar will present the synthesis and characterization of the metal sulfide and organic perovskite semiconductors for their applications in thin film solar cells. The microfabrication and characterization results of tin sulfide semiconductor will be mentioned. The higher transmittance of n type cadmium oxysulfide was used as an alternative in order to increase the visible range of transparency and this film can enhance the visible light reaching to photo-absorber that helps in the increment of photovoltaic efficiency. The photovoltaic applications of these materials will be explained. He will also mention the microfabrication of flexible RF antenna devices.
