Reliability analysis and condition monitoring of polymer based dye sensitized solar cell: a DOE approach

Abstract

Abstract Organic Photo Voltaic cells such as dye sensitized solar cells (DSSC) are bringing about a revolution in the sustainable field. Better economic feasibility and decent efficiencies make it more eminent amongst the available products in the market. Reliability of these cells becomes an area of concern as environmental and electrical energy parameters wobble dynamically. The research article focuses on new techniques for observing the lifetime of a DSSC experiencing the impact of warning parameters like light source temperature, frequency, humidity and thermal stresses on working factors of DSSC such as Fill Factor, voltage, current and Efficiency. Optimization of prediction of failure for lifetime of the cell is done by Design of Experiment (DOE) methodology based on Taguchi’s model using Minitab 18.1 software. The health condition of fabricated dye sensitized solar cells (DSSC) is monitored using Accelerated life testing as well as analytical method. Analysis shows that the mean lifetime of the fabricated dye sensitized solar cells (DSSC) using the experimental method and analytical method is 18 488.67 h and 22 167.05 h respectively. The error analysis shows that the analytical method has 3.63% error, which confirms its accuracy as 96.37%.
