Link To Cell Instead Of Getting Cell Data

I want to create a summary page with the tab name and a link to the contents in a specific cell. In the code below, I can get the sheet I want but in the second column, I would like to link to the data instead of getting the data in the cell. Can I do this with a simple modification to this

Dim a As Long
Sheets.Add.Name = "Notes"
For a = 1 To Sheets.Count
Worksheets("Notes").Cells(a, 1) = Worksheets(a).Name
'The next line gets me data, but I want to link to this cell in all worksheets
Worksheets("Notes").Cells(a, 2) = Worksheets(a).Cells(15, 18)
Next a
