Here's what I found at one source:


For each 1 ounce semisweet chocolate called for in a recipe, use 3
tablespoons semisweet chocolate chips
OR
1 tablespoon unsweetened cocoa, plus 1 tablespoon granulated sugar
plus 1 tablespoon vegetable shortening
OR
1/2 ounce unsweetened chocolate plus 1 tablespoon granulated sugar;


Another source:
To substitute for 6 ounces of semi-sweet chocolate, melted, or a cup
of semi-sweet chocolate chips, melted, use six tablespoons cocoa plus
1/4 cup shortening plus 7 tablespoons sugar.


Another source:
Substitute for 1 ounce semisweet chocolate: use 3 tablespoons
semisweet chocolate pieces or 1 ounce unsweetened chocolate plus 1
tablespoon sugar.


So, which would say sounds best? Thank you.
