Performance analysis of dye sensitized solar cell based on ZnO compact layer and TiO2 Photoanode
(BRAC University, 2018-09) Rahman, Abdur; Mahmud, Md. Ashik; Haque, Md. Injamamul; Bhuian, Md. Belal Hossain
Harnessing solar energy as an alternative solution to power production. Power can be produced through burning fossil fuels. To gain optimum benefit through solar energy is an extreme challenge for scientists and researchers nowadays. Solar power generation is consistently improving through the decades and third generation dye sensitized solar cell can play an important role as a solution. Dye sensitized solar cell approaches to high efficient thin film technology. Efficiency can be increased by adding more cells of different band gap to a cell stack in Tandem cell. In this ongoing study, a double layer structured dye sensitized solar cell has analyzed where ZnO and TiO2 composited photoanode were prepared on FTO. The Photovoltaic characteristics, I-V & J-V curve were evaluated for different thickness, absorption coefficient and wavelength. DSSC solar cell characterization techniques such as current-voltage and spectral response measurements were analyzed to evaluate the cell performance.

Quality Issues in Denim Production

The project is on the "Quality Issues in Denim Production. This study examines what is significant for high quality of Denim, and what processes and factors affects the intrinsic quality of the Denim Fabric. Based on this, compilations of reclaim statistics was made and interviews and quality testing was conducted to see if high quality requirements is key to both produce denim of good quality and to reduce the number of complaints. Our Denim industry is an incorporated industry so it is compulsory to check the procedures from the earliest starting point. It moves toward becoming from the yarn to the completed item. We are here attempted to represent the quality parameter in the Denim division. Quality management is an important part of the day-to-day business of a company and should permeate the entire organization and all processes. In order to create denim with high quality, quality testing is an important part of a quality management. Quality tests are made to ensure that the products meet the demands and expectations on its properties. Quality tests also play an important role in the compilation and analysis of customer reclaims. Despite the quality and quality tests, there is a risk that dissatisfied customers reclaim products they are not happy with. To relate customer claims against the quality of tests is a good way to evaluate what the problem is, or if it even is a problem. The study showed that high quality could be the solution to ensure the production of denim with high quality. However, the problem is complex and therefore, the solution to reduce claims and high-quality products to be something else or part of the solution. That goes for any company to be familiar with the underlying quality dimensions and based on that analyse where the critical points are found in their product development and manufacturing process. For the company of this study, the authors consider that the solution does not lie in raising quality requirements, but rather that the sewing should be improved and more quality control over garment measurement lists should be made. Quality tests cannot Page | 5 prove a lack of quality material and thus the authors consider that much of the claims are due to good will.
