Incorporation of the Dye Sensitized Solar Cell Research results into Solar cells and Modules Course Dye Sensitized Solar Cells (DSSCs) fabrication technology is gaining momentum asa low cost and simple fabrication technology to convert solar energy into electric energy.A systematic study of the DSSC fabrication procedure and its influence on the cellefficiency are presented in this paper. The significant process improvements made toenhance cell efficiency are: preparation of titanium dioxide (TiO2) layer, TiO2 layersintering, composition of the dye absorption solution, and the sealant material thickness.The Coatema tool was used to develop an automated TiO2 coating process and achievedlayer thicknesses in the range of 8-13 µm with repeatable TiO2 weight loading andminimal micro cracks. The cell size and its influence on the cell efficiency are alsoincluded as a part of this study. The process optimization steps made in this studyenhanced cell efficacy over 200% and significantly reduced process time. The intent ofthis paper is to incorporate these research findings into the classroom. The DSSCfabrication can be easily incorporated into a classroom with some hands on activity forthe students to participate. Since the DSSC is compact in size and portable in naturemake them attractive to be applicable in portable electronic devices such as laptops, cellphones and/or any other portable devices. The student learning and understanding ofconverting solar energy into electricity can be easily demonstrated using the Dyesensitized solar cells. The targeted course for incorporating these research results is Solar Cells andModules is a senior undergraduate course required for all students majoring in theconcentration, Alternative Energy Technologies in BS degree program. This course isalso offered as an elective for other majors. The research results will be used to explainthe design characteristics of the solar cell and how the fabrication procedure influencesthe device performance. The students will have an opportunity to go into the lab andperform testing of the pre-fabricated DSS cells and/or participate in fabricating a cell.This experience will definitely be rewarding to the students and will be able tounderstand the function of the solar cells with better clarity.
