DEVICE PERFORMANCES AND SIMULATIONS FOR SEVERAL KINDS OF LARGE-SCALE THIN FILM SILICON SOLAR CELL MODULES - INTRODUCTION OF SUPER SEE-THROUGH THIN FILM SOLAR CELL MODULE AND APPLICATIONS

摘要

We fabricated large-scale thin film silicon solar cell modules with amorphous silicon and micro-crystallized p-i-n structure on a TCO film by a PECVD system. We also developed the device simulator for conventional and see-through thin film solar cell modules, and simulated their cell performances in order to estimate the influences of some electrical factors such as a series resistance, a shunt pass and its distribution. We confirmed the initial conversion efficiency of 12.1%(Pm 58.4W, Im 1.22A, V{sub}(oc) 67.4V, F.F. 0.711), corresponding to about 11% stabilized conversion efficiency and the initial conversion efficiency of 10.0%(Pm 48.1W, Im 1.05A, V{sub}(oc) 66.4V, F.F. 0.717) of a super see-through thin film solar module with 10% transparency with the same substrate size of 560×925mm.
