Could amorphous silicon (a-Si) [[solar]] panels be a good way to replace [[fossil fuels]] on a massive world scale{{x|i.e. covering almost every rooftop}}? Maybe.

{{considerations}} __NOTOC__
==Considerations==
===Scarce minerals===
{{basically|Probably avoidable}}
a-Si solar panels can probably be manufactured with very little rare-mineral content.{{rn}} Performance efficiency would be low but production would be far more scaleable.
* Note that germanium-based options (aSiGe) would [[solar panel minerals|not be scaleable enough]].
* If copper is too scarce, some internal wiring could probably be replaced with aluminum (far more abundant) if we're willing to give up some efficiency.{{qn| - how much loss? hopefully not a lot}}
* Do a-Si cells need to have silver in them? Or is that only for [[crystalline silicon]] panels? {{rn}}
* Solar panels often contain lead-based solder, which isn't too scarce but is toxic and could create problems in the long run as old solar panels eventually must be disposed of. Wikipedia says that the lead could be replaced with other types of solder.{{en}}
* So essentially, make a lot of cheap panels from mostly silicon and aluminum (both extremely abundant minerals).
===Efficiency===
{{basically|Low but probably good enough}}
If it's 6% without scarce minerals{{rn}} then that would be enough for [[rooftop solar]] if all rooftops are covered.
===Energy in manufacturing===
{{basically|Probably reasonable}}
Less energy-intensive than [[crystalline silicon]], but probably still somewhat energy-intensive. {{qn| - [[EROI]]}}
===Lifespan===
{{basically|{{rn}} }}
{{empty}}
===Reliability===
{{basically|{{rn}} }}
If cell characteristics vary too much due to manufacturing defects and random failures, maybe a [[wattage adder]] circuit could allow the solar panel to still function robustly in any case? {{rn}}
===Recyclability===
{{empty}}
