Solar panel - blocking diode - DC to DC converter
It’s a bad idea .  You want to detect the solarity with a PD then regulate the Vpv down from 83% to 72% of Voc max  with a matched impedance of Vol/Isc which rises as solarity  decreases then use a step up current source that obeys this while limiting the output voltage and cutoff.
This step up current stores energy in V=LdI/dt * t then dumps it faster into the battery in a continuous low ripple at lower voltage. Thus choice of L and f are critical.
A cap across PV stores current also for each cycle in order to keep the PV current constant.
Using two inductors and alternate switching improves efficiency greatly to keep Ipv more constant in Continuous mode.
