Study on Thermal behavior of Flexible CIGS Thin Film Solar Cell on Fe-Ni Alloy Substrates using Finite Element Analysis

Design of optimization of thin film solar cell module based on Cu(In,Ga)Se2 (CIGS) is investigated through a simulation model. At first, a numerical model which is equivalent to a practical cell module and represents one diode electrical circuit method is sought in FEA (Finite Element Analysis) and several parameters are adjusted. In FEA, the distribution of electric potential within each layer is shown with accordance to the given inputs. Next, to find the optimal design, four design variables (factors) which have three levels each are chosen and Design of Experimental (DOE) is performed so that the order of influences to performance is arranged. In DOE, a series of simulation follows the prepared orthogonal array, which is a sort of combinations by factors and levels, then analysis of variance (ANOVA) table is built up to screen unimportant design variables. Finally, the surface response function, which represents the relationship between important design variables and the purposed performance such as efficiency and fill factor (FF), is found and shown into equipotential graphs.

In this paper, a finite element code especially for micro-magnetostrictive actuators was developed. Two significant characteristics of the presented finite element code are: (1) the magnetostrictive hysteresis phenomenon is effectively taken into account; (2) intrinsic geometric feature of typical thin film structures of large length to thickness ratio, which makes it very difficult to construct finite element mesh in the region of the thin film, is considered reasonably in modeling micro-magneostrictive actuators. For verification purpose, magnetostrictive thin films were fabricated and tested in the form of a cantilevered actuator. The Tb-Fe film and Sm-Fe film are sputtered on the Si and Polyimide substrates individually. The magnetic and magnetostrictive properties of the sputtered magnetostrictive films are measured. The measured magnetostrictive coefficients are compared with the numerically calculated ones.
