Customer ServiceThese finding can suggest that boron content in aluminum pastes is supportive to improve the bulk quality of silicon solar cells. However, poor performance of such pastes on solar cell fabrication is needed to be investigated further for higher efficiencies. 1.
The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
Conclusion Screen printable aluminum pastes with and without boron content were introduced in this work for crystalline silicon solar cells. Both pastes provided high carrier lifetimes after alloying by thermal processing.
Commercially, the efficiency for mono-crystalline silicon solar cells is in the range of 16–18% (Outlook, 2018). Together with multi-crystalline cells, crystalline silicon-based cells are used in the largest quantity for standard module production, representing about 90% of the world's total PV cell production in 2008 (Outlook, 2018).
During the past few decades, crystalline silicon solar cells are mainly applied on the utilization of solar energy in large scale, which are mainly classified into three types, i.e., mono-crystalline silicon, multi-crystalline silicon and thin film, respectively .
The standard for modern c-Si PV production is wafers with a thickness of m. At the same time, a further reduction in the thickness to less than 100 ]. Thus, an attractive alternative appr oach to solar cell production is the cost-effective fabrication of high-quality crystalline Si thin films. of the crystalline material typical of c-Si technology.
