10 Questions
What is the main advantage of lithium air batteries?
High theoretical specific energy of lithium
How is the lithium electrode protected in lithium air batteries?
By a solid electrolyte interphase (SEI)
What are the proposed main discharge products in non-aqueous lithium air batteries?
Li2O2 and Li2O
Why does the oxygen electrode need to be porous in lithium air batteries?
To allow the transport of gases
In the case of aqueous lithium–oxygen batteries, what are the theoretical specific energies like compared to non-aqueous lithium air batteries?
Lower
What happens when sunlight is incident on silicon solar cells?
Photon strikes on p-n junction, creating electron hole pair which diffuses towards respective layers based on affinity
What is the main reason for low efficiencies in two-component organic photovoltaics (OPV) initially?
Reliance on bilayer cells made exciton dissociation and diffusion challenging
What is the role of the acceptor in organic photovoltaics (OPV)?
To assist in dissociating excitons and accepting electrons
What is the approximate distance excitons can diffuse in organic photovoltaics (OPV)?
Approximately 10nm
What happens when electron hole pair diffuses towards the n-type layer in silicon solar cells?
Current is generated in the externally connected circuit
