two major types of solar panels.
thin film; the kind that is plastic, and therefor will not stand the test of time as all plastics don't, and therefor has planned obsolescence built-in, and therefor is not really desirable, and is why some well backed companies have gone under for backing thin film (solynra et al)... well it doesn't use lead in it's manufacture.
silicon crystal; uses gallium (easy to mistake for mercury). Gallium melts at a really low temp, but it is not mercury. The gallium is used as a dopant to create the NPN or PNP. or whatever.
easy mistake to make man.
