I have a solar panel rated at 5V 80mA and want to increase the output current significantly higher to around 500mA and decrease the voltage to either 3V or minimum of 2.7V, how can I go about this?

I understand physics, but I need to know can a buck converter increase current this high from a step down of 2V?

I am trying to power a Module that needs 2.6-3.6V and a minimum of 400mA to turn on. But then I only need an average of 50mAh to stay on during the day.

The solar Panel below: https://store.sundancesolar.com/5-0v-80ma-solar-cell/

Also I have been thinking about using a Supercapacitor because I only need 500mA for 1 second to startup my module. And then an average less than of 50mAh5mAh to keep it on.
