A photon or light particle that comes from the sun has a certain amount of energy. Blue photons for example have an energy of 0.4 aJ. Red photons have half that energy.
If a photovoltaic cell is built, a certain energy band gap is chosen. If it is too large, a photon will not be absorbed, if it is too small, part of the energy is lost.
For instance if a photon of 0.4 aJ hits a solar cell of 0.3 aJ band gap, it will be absorbed and create an electron with energy 0.3 aJ. This gives an efficiency of 75%. If a 0.2 aJ photon hits this solar cell it will not be absorbed. Of the total energy of 0.6 aJ hitting the solar cell only 0.3 aJ is absorbed, a total efficiency of 50%.
The highest efficiencies are reach with solar cells that contain several layers with different (decreasing) band gaps.
Blind
Cells with a cell wall.Because cell wall stiff shape cant be changed.
it cant make energy it is kinetic if it flows
Well, the answer could possibly be photosynthesis but that is with chlorophyll. ATP is a source of energy, also.!!
If a tree cannot photosynthesize, it may obtain energy through stored nutrients in its roots, trunk, and branches. Another possible source of energy could be from organic matter in the soil that the tree can absorb through its roots. In some cases, trees may form symbiotic relationships with fungi or other organisms to obtain energy.
no it cant, because it is from the sun, and we cant control the suns heat
Energy can be transformed from one form to another through processes like burning fuel to release chemical energy as heat, converting mechanical energy to electrical energy in a generator, and transforming solar energy into electrical energy through photovoltaic cells. These transformations follow the laws of thermodynamics, which dictate that energy cannot be created or destroyed, only changed from one form to another.
Actually you can. A photovoltaic cell (a.k.a. solar panel) does precisely that.
no they cant, it erupts because of the build-up of pressure
Your eyes switch receptor cells from mostly cones to rods, which is why you cant see color in the dark.
This is because chlorophyll in the plants allow them to absorb the suns energy and turn it into sugar through a process called photosynthesis. Animals do not contain chlorophyll within their bodies therefore they are not able to produce these sugars.
Exercising cost lot of energy.So Oxygen requirement increase.People with sickle cells, do not have normal number of blood cells to carry Oxygen.So energy production would not be sufficient.
they can save other chloraplasm
It cant
no they cant
no they cant
learn this answer because i cant find it and i need to know it. thank u
