The theme of transformation is quite prevalent. Love has the potential to transform the Joker, at least to some extent. It could be in his actions, his thoughts, or his view of the world. Fanfictions often explore how this transformation occurs and what it means for the Joker and those around him.
Isolation is also a theme. The Joker is usually a very isolated character, and when he falls in love, it's about how he deals with this new connection and whether he can break out of his self - imposed isolation. Also, the theme of sacrifice often comes up. He may have to sacrifice his old ways or face difficult choices to keep the person he loves safe.
One common theme is the idea of 'forbidden love'. Since the Joker is a villain, his love is often seen as something that goes against the norm. Another theme could be 'redemption through love', where his love for someone might make him question his evil ways.
Often, the power dynamics play a big role. The Joker is a powerful and feared character, so seeing how he interacts with a love interest in terms of power - whether he uses it to protect or control - is a common theme. Also, redemption can be a theme. Some fanfictions might explore if the Joker can be redeemed through love, although this is quite a controversial idea considering his heinous acts in the original comics.
Common themes in 'Joker in love with Batman fanfiction' include the power dynamic. The Joker, despite being in love, still wants to have power over Batman.

Another aspect is the exploration of the Joker's psyche. His love for Batman could be a result of his own mental instability, and many fanfictions dig deep into this to understand his motives better.
