DOPING OF SEMICONDUCTING THIN FILMS
About author : I am Vinod Deoram Bhabad from Pen-Raigad, Maharashtra. I am working as an Assistant Professor in Chemistry in B.N. ASC College, Pen. I have completed my Msc, Mphil and PhD in the field of Chemistry. I also conduct remedial coaching classes for socially backward class students. I work in different administrative committees at the college front. I have published 16 research papers in National and International journals with good impact factor and citations.My area of research is Thin Films. I would like to contribute my research knowledge to the students and improve the education system. Innovative practices, social gatherings, study campaigns, interactive sessions collectively form a major part of my teaching. I believe in using different brainstorming sessions for students that would help them analyse and learn more about the subject on their own.
About book : Hard work is going on in finding novel resources for solar power alteration. Dual essential parameters must be considered in manufacturing of such materials. They are optical gap corresponding to solar range and affordability of fabrication price. Between the materials of abundant attention are crystalline metal chalcogenides. Numerous semiconducting photoelectrodes were comprehensively considered for electrochemical generation of current by using radiation in terms of continuous and effective trap as well as exchange of solar power. This dissertation illustrate the synthesis and characterization of polycrystalline cadmium selenide/trivalent ion like aluminum doped cadmium selenide/ monovalent ion like copper doped cadmium selenide thin films. Solar cells maintain great hopes to be used an environmental friendly and economically feasible renewable power sources. For this purpose semiconductor materials are being investigated. In the present investigation, deposition of cadmium selenide/aluminum and copper doped cadmium selenide samples by dip method applying amorphous as well as metallic templates. Aluminum trichloride, cadmium sulfate, ammonia,trichloroacetic acid, aluminum trichloride, sodium selenosulphate and copper chloride were utilized to deposit the samples. Diverse depositary considerations were outlined to acquired excellent samples. The materials have been characterized via XRD technique, SEM method, optical absorption measurement and electrical characteristics. The sample undergoes photoelectrochemical and thermoelectrical determination. Cadmium selenide films show dark red in color. For aluminum and copper doped samples different shades and dark brown color was obtained correspondingly. The extreme thickness of cadmium selenide became observed 0.54μm, aluminum doped sample indicates 0.74 μm as well as 0.70μm for copper doped samples. Each sample indicates hexagonal structure. Cadmium selenide and aluminum doped sample represents a strong peak o
