Multi-crystalline silicon is produced by the directional solidification (DS) method. In the past it has been the main material for solar cells due to lower manufacturing costs than Mono crystalline silicon growth. However, solar cells made from Multi-Si have disadvantages in photoelectric conv...
PROBLEM TO BE SOLVED: To inexpensively manufacture a large member of Si crystals for solar cells by extracting a mixed acid composed of at least a plurality of kinds of acids to lower the residual concn. in a Si wafer below a specified value, and melting/recrystallizing the Si wafer to ...

摘要: Results on the creation of a current-collecting grid for heterojunction silicon solar cells by ink-jet printing are presented. Characteristics of the obtained solar cells are compared with those of the samples obtained using standard screen printing....
The use of lower purity, lower cost, "solar grade" silicon for crystal growth feed stock has been proposed as one means to reduce the cost of solar cells. The metallic impurities in this material have a deleterious effect on cell efficiency; however, the maximum tolerable impurity concentrations...
