As I know, most of the cells used in spectroscopy (eg. IR cell, UV cell, etc.) are made of quartz, a crystalline form of SiO2. What is/are the most important factor(s) that we used quartz-material spectroscopy cell but not cells made of other materials?

[P]

It is because they don't absorb in the UV/VIS/IR range - thus not interfering with your spectrum.

But,is there any other material which is also not interfering the spectrum?

This site lists some salt cells that are used for IR measurements.  Quartz is generally used in UV spectroscopy because water is the most common solution that the compound of interest is dissolved in (i.e. a salt cell will dissolve and be destroyed).

In my electrochemical FTIR experiments I use Calcium Fluoride. Even though the watery solytion will slowly dissolve it, with careful polishing the crystal is kept in good order for a long time.

The cell itself is just ordinary glass (the disassemlable bottom is calcium fluoride)

Dear DevaDevil,

At least for UV/Vis the Information on "International Crystal Laboratories" above seams to be not very adequate.
A much better info source for UV/Vis is:  HELLMA
You will find it on::  http://www.hellma-worldwide.de/en/default.asp
If there, select first "products", then "cells". (Die selbe Info gibt's auch Deutsch!).
In case you need only the Vis-Range, you may use cheep "Styrol-Cuvettes", but take care, because then your results may be also of "cheep" Quality!

For "strong" cleaning search on Yahoo! for:   Aqua Regia and cuvettes

Good Luck!
