The most promising material for these devices is amorphous, is "hydrogenated" to passivate its high density of dangling bonds, and is especially great when paired with an alloy of itself and either germanium or a microcrystalline form.

Polycrystalline (*) silicon dominates for these devices due to the bulk of material required. Because they are operated in reverse bias, a current is created when electrons are collected at p-side contacts and holes at n-side contacts due to the impact of a photon with energy greater than the bandgap. For 10 points, name these devices that convert sunlight into electrical energy.
