I think you are losing your mind: you wrongly buy put. And then try to find every reason that your wrong bet can win back. People who don't recongnize trading mistakes doom to fail. Now your FSLR put will become worthless.
As to FSLR solar cell technology, their first rate scientists know much better than you laymen. A simple fact is that as long as your handhel calculators or wrist watches are safe, then FSLR technology will be safe -garanteed, because they use same elememts...for further information read..

Environment CdTe Technology Print This Page Email This Page First Solar's advanced CdTe technology is instrumental in accomplishing our environmental mission. CdTe is uniquely capable of producing low cost solar modules, making widespread, cost-effective solar electricity a reality. Its physical properties are optimal for converting sunlight into electricity, resulting in highly efficient photovoltaics with thin (< 3 micron) semiconductor layers. CdTe is a robust material with the demonstrated capacity for high volume, low cost production.
CdTe is a semiconductor made by transforming cadmium and tellurium from their elemental forms into a stable semiconductor. The cadmium in First Solar's CdTe is derived from zinc smelting waste. The ��up-cycling�� of cadmium into safe, cost effective solar electricity not only reduces the toxic effects of fossil fuel generation but prevents potentially dangerous elemental cadmium from entering the environment. For these reasons, research from the U.S. Department of Energy's Brookhaven National Laboratory concluded:
Large-scale use of CdTe PV modules does not present any risks to health and the environment, and recycling the modules at the end of their useful life completely resolves any environmental concerns. During their operation, these modules to no produce any pollutants, and furthermore, by displacing fossil fuels, they offer great environmental benefits. CdTe PV modules appear to be more environmentally friendly than all other current uses of Cd.
