Abstract: | The research work focuses on two key areas (i) Optimization of high efficiency hetero-junction thin film solar cells to act as sensors (ii) Image processing of any rigid object present inside dense fire. Thin film solar cells are taken into consideration because of their cost effectiveness and high photo conversion efficiency. Especially copper based semiconductors in the form of Cu2InGaSe4 and Cu2ZnSnSe4 thin film solar cells show very high efficiency. In absorption range, they cover a wide region of the solar spectrum. The material components of CIGS and CZTS solar cells are earth abundant, cost effective andnontoxic. Thin film solar cell fabrication is a state of the art technology which is the only hope for future generation for plant scale clean energy. We havemade an attempt to fabricate CIGS and CZTS high efficiency thin film solar cells using both physical and chemical methods. The methods involved in deposition of various layers under predetermined conditions include sputtering, co-evaporation, chemical bath deposition and electro-deposition. The cross sectional view and surface morphology of the solar cells have been investigated using X-ray diffraction, scanning electron microscope and Raman spectroscopy to investigate thelayer growth and crystalline structure. Firefightingin industrial, military and civilian sectors is a high risk concernthat needs technical assistance for exploring dangerous fire scenario to identify victims and valuables. An attempt has been made to develop a portable and compact arrangement to capture the image of any object and process the image to hasten the object identification process newline |
