Term (Index) Definition
solar cell  two-terminal semiconductor device which converts solar light into electric signal; requires presence of potential barrier within semiconductor which is typically accomplished by the formation of a p-n junction; potential barrier separates hole and electrons generated by irradiation of semiconductor establishing different potential at device terminals; because of the low cost, solar cells using amorphous silicon are the very common in spite of the fact that their efficiency is lower than efficiency of solar cells made out of polycrystalline, multicrystalline or single-crystal silicon; semiconductors other than Si are also used to manufacture solar cells.
amorphous material  non-crystalline solid; no periodicity and long-range order at all; lower quality than crystalline materials but cheaper to form; amorphous semiconductors are useful in large-area applications such as solar cells and flat panel displays; insulators used in semiconductor technology, e.g. SiO2 and Si3N4, are typically amorphous.

photovoltaic effect,  generation of a potential difference(open circuit voltage) at the terminals of an unbiased semiconductor diode (almost uniquely a p-n junction, altough, in principle, also a metal-semiconductor junction) as a result of illumination with light featuring energy higher than the energy gap (Eg) of semiconductor; fundation of the semiconductor solar cells operation.
multicrystalline material  just like polycrystalline material maintains long-range order only within limited in volume grains; it differs from polycrystalline material in that the grains(i)in m.c. material are larger and (ii)are typically significantly expanded along the direction of solidification (z direction); also m.c material is in the form of wafers cut out of the ingot rather than thin-films; rarely used in device manufacturing until multi-crystalline Si was found to offer advantegous cost vs. efficiency relationship in solar cell technology.
