Solar cells are renewable energy source which is not only environmentally friendly but also economically viable. For that matter, thin film materials are in observed with great in terest by a number of sources throughout the nations. Among these, CdTe (Cadium telluride) and CIS (copper indium diselenide) are the latest commercial products that are gathering attention in the solar cells markets. However there are some downsides to this newly invention. Since the materials are embedded, in the occasion of damage, certain amount of module residue can be released to water or soil. This paper outlines the results of our outdoor leaching experiments on photovoltaic (PV) samples broken into small fragments and been observed for 1 year.
