Assertion: solar cell's layer | /r/HasAspect | a naoh surface texturation
Facets:
value: usually
type: TEMPORAL
value: in order to increase the transmission coefficient t
type: PURPOSE
value: with several pyramids
type: OTHER
Source sentences:
text: The top AR layer has usually a NaOH surface texturation with several pyramids in order to increase the transmission coefficient T, the trapping of the light in the material (because photons cannot easily get out the MJ structure due to pyramids) and therefore, the path length of photons in the material.
