Conversion losses are on the order of 5-15% Splitting hairs, but a 23% efficient mono perc panel will edge out a 19% poly silicon panel even if utility conversion is a lot better. Although I think in that specific case the perc panels are cheaper now for utilities too. If you're using it at 12V and/or you shelled out the extra money for multi junction in your caravan you're probably still ahead. There will also likely be 5 years or so after hybrid perovskites hit the market before anyone is keen to put down big money on the lifetime predictions.
