among the materials that have been found promising are amorphous silicon (a-si), polycrystalline silicon films, cadmium telluride (cdte) and copper indium diselenide (cuinse2) (referred to commercially as cis, or cigs when gallium is also added).
具有潜在用途的材料有非晶形硅（a-si）、多晶硅膜、碲化镉（cdte）和联硒化铟铜（cuinse2，商业上称为cis，如果还含有镓，则称cigs）。
