| Abstract(in English) | Multi-crystalline silicon solar cells are characterized by using mesa structures formed by wet etching. Solar cell performance was analyzed based on dark current-voltage characteristics of various mesas with diameters of 0.2-1.2mm. The sample with a high efficiency of 13.37% has 63% of good mesas with a lower leakage current less than 10^<-4>A/cm^2. Whereas, the sample with an efficiency of 4.7% has 13% of good mesas. Minority carrier lifetimes were determined from recovery switching transients for each mesa. The lifetime was correlated with the leakage current. By the analysis of local characteristics, a new evaluation technique for multi-crystalline silicon solar cells will be developed. |
