摘要
An apparatus for estimating and evaluating characteristics of large-area series-connected solar battery cells from a measured current-voltage characteristic of a small-area single cell, includes an analysis model construction unit, an analysis operation unit and an evaluation unit. The construction unit reads shape parameters and material physical properties of the cells and automatically constructs a finite element method model. The operation unit obtains a current at a voltage based on the measured characteristic, sets the current as a current load, calculates potential distributions of transparent electrode and rear electrode of the cells, corrects the current load based on a difference between the distributions and the measured characteristic, recalculates the distributions based on the corrected current load, and repeats the recalculation until the distributions converge. The evaluation unit evaluates whether a converged calculation result is a pattern exhibiting a desired current-voltage characteristic of the cells.
