| Popis: | 27th European Photovoltaic Solar Energy Conference and Exhibition; 973-976 In this work Pillar Ltd presents the results of development of technology for growing mono-like crystalline silicon ingots for photovoltaic application, which has a number of advantages resulting in a relatively low production cost and high material quality. Experimental mono-like silicon ingots and wafers were produced. Electrophysical properties of produced material were investigated. The parameters of mono-like ingots were compared with those of multicrystalline silicon ingots produced at Pillar Ltd using traditional technology of directional solidification. Mono-like ingots gain a number of advantages over directionally solidified ingots: more homogeneous crystalline structure and higher minority carrier lifetime. Mono-like ingot slicing made at Pillar resulted in high-quality wafers with significantly big crystalline grains of orientation. Solar cells and modules were produced of wafers from mono-like crystalline ingot with application of high effective alkaline texturing. Cell efficiency and module power distributions are reported. Obtained values are approaching the ones for monocrystalline cells and modules. Presented results confirm the promising use of mono-like technology for solar cells application. |
