Aubergines and chilli/peppers. Which prefer the hottest temp / most sunlight?

After a disastrous time with cucumbers in my greenhouse I decided that I would take them out and move the aubergines / chilies / peppers around to give them more space. I've put the aubergines into the greenhouse that where the cucumbers were and gets the most sun and often gets the hottest, however, I'm wondering if I should have moved the chillies /peppers there instead? The greenhouse the chillies /peppers are in gets a lot of the morning sun but is shaded from mid-afternoon.
Everything is in pots so not a problem to move them.
What should I do as I don't want to loose the aubergine fruit that are beginning to grow if the greenhouse they are now in will be too hot?
