The CUPID-0 experiment searches for neutrinoless double beta decay using the first array of enriched (ZnSe)-Se-82 scintillating bolometers with double (heat and light) read-out. To further enhance the CUPID-0 detector performances, the heat-light correlation has been exploited to improve the energy resolution. Different decorrelation algorithms have been studied and the best result is the average reduction of the full width at half maximum (FWHM) energy resolution to (90.5 +/- 0.6) % of its original value, corresponding to a change from FWHM = (20.7 +/- 0.5) keV to FWHM = (18.7 +/- 0.5) keV at the 2615 keV gamma line.
