did you mean Photoamptics ?

No, that's not a thing

Efficient for what goal retard? Reducing CO2? Generating electricity? Decorating a house? Employing STEM-cells?

PV if you ignore EROI, probably plants if you take into account the EROI. At least for now, "superplants" are a possibility in the near future.
Always talking about the "raw stored energy", plants are terribly inefficient if you need a liquid fuel as final product (bioetanol, biodiesel, oils, distilled resins)

the two measurements should: photon absorption and rate of conversion to usable energy
This is the proper way to tell which is more efficient

In actuality, however, plants do not absorb all incoming sunlight (due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels) and do not convert all harvested energy into biomass, which results in a maximum overall photosynthetic efficiency of 3 to 6% of total solar radiation.[1]

Photovoltaics and it's not even close. The reason being that the plant has other constraints to account for, such as water, temperature, osmosis, other cellular processes, etc. which reduce its efficiency.

You mean photoinduction?

Photosynthesis. It has a 99% efficiency rate after photons hit the chlorophyll, meanwhile solar panels are around 10%-20%.

quantum efficiency =/= energy conversion efficiency.
Semiconductors are ~100% QE for a limited bandwidth

silly post but the photons are creating a voltage difference in the semiconductors and thereby producing a current.

If judged by price, photosynthesis is much better. You can get plant seeds for free or just a couple of cents, and the plant does the rest for free

It's a retarded question as plants self replicate out of basically dirt and air and biodegrade into dirt and air. You literally can't invent a more perfect convertor of solar power to packets of energy. You just can't. You can't out invent nature you hubris licking cunt.
There is nothing more elegant and well designed than God himself has made. All of science and invention is just man trying and failing to imitate God's inventions.
For all the achievements of man I see only folly, failure to create a dragon fly let alone a better dragon fly. Failure to surpass the might green leaf in it's power to make sun into energy. All the effort of billions of humans and the solar panels are a fraction as efficient, made by strip mining the crust for minerals(inefficient) and then dumped to toxic waste when expired(inefficient).
So we have an inefficient device that is made in a very inefficient way and it's disposable after the fact is equally inefficient.
PS, all the above holds true for carbon sequestration. No device you build will rival a tree in this regard, it just won't You can't build huge facilities out of steel and concrete(which makes C02) and think it can out compete a fucking tree. Worst case you bio engineer the tree to be more efficient or grow faster. That's all you need to do. But you can't make money off that and once the GMO tree seeds got out they could be propagated across the globe for the cost of shipping. Instead they want to build huge facilities run by mega corps that charge you money every month to "suck the carbon out of the air".
Anyone claiming anything is more efficient than nature is lying to you.

what's nature's answer to making plutonium then, seems at least in earth conditions humans managed to do it better
