The MAX17710 is a complete system for charging and protecting micropower-storage cells such as Infinite Power Solution's THINERGY® microenergy cells (MECs). The IC can manage poorly regulated sources such as energy-harvesting devices with output level

Note that you can never increase "power"; increasing the voltage decreases the available current, in proportion (and less losses due to conversion inefficiencies).
The challenge is to secure a sustainable power source that drives sensors and radios in systems that use IoT. Use of renewable energy that has been so far too small to be useful is now effective. Asahi Kasei Microdevices (AKM) provides low-input-power start-up energy harvesting ICs.
Unfortunately I am a rookie when it comes to circuit boards I have just started to learn and teach myself about this, watching YouTube videos etc, I have been disabled for 3 years now and am wanting to learn new things. I have most components to hand I just need help my head is aching from being so frustrated about this lol.
Just to give you an idea of the power available, a typical power LED (on say a television) will take ~5mA at 2V so about 40 times more than you have available.
Trying your question on a different forum is unlikely to produce more optimistic results. What you want to do will be a challenge without auxiliary power supplies.
A typical very small 12V > 240V power inverter will need 2 - 3W just to turn on with no load connected.
That is over FIVE HUNDRED times more power than you have.
To put it in proportion, you have probably enough to run something like a wristwatch marginally enough for a battery wall clock, something where a tiny battery lasts several years.
Or, if you substituted an alkaline AA cell for your power source, you could draw the same amount of power from that for around two to three years, with a lot less messing about.
I suggest you look at more conventional electronics projects, as the only thing you will ever get from this idea is frustration.
