Why does PsExec hang after successfully running a powershell script?
Turns out this is a common problem. Found the solution a here. Essentially, if you pipe some data on stdin with cmd it will return propertly after execution (because it is being run via cmd, not powershell).
psexec \\target -u domain\username -p password cmd /c "echo . | powershell c:\path\script.ps1"
I know the answer comes late it would have already been figured out, If not it might be useful for future visitors.
STDIN has to be re-directed in powershell execution inorder to be able to come from hang (Here it waits in STDIN). to be able to do this use -inputformat none
powershell -inputformat none -File powershell_script.ps1 will work.

psexec \\target -u domain\username -p password -d powershell c:\path\script.ps1
Also fixes the problem.
-d flag for psexec is like "run and exit" in a non-interactive way:
-d Don’t wait for the application to terminate.
Only use for non-interactive applications.
