Germanium diodes ( or sometimes Schottky diodes ) are used instead of silicon diodes, because their lower forward voltage drop ( roughly 0.3V compared to 0.6V ) makes them more sensitive.

Notice that the lights are two-deep in series and then in parallel-if the forward voltage drop on the LEDs is 3.2-3.6v, should that be fine?

:: : The LEDs which I'm looking at buying ( taking into account their brightness ) have a forward voltage of 3.3 V but can tolerate a max of 3.8.

A silicon diode has a typical forward voltage of 600 700 mV, while the Schottky's forward voltage is 150 450 mV . This lower forward voltage requirement allows higher switching speeds and better system efficiency.

Since the reverse voltage of a shaded cell is much greater than the forward voltage of an illuminated cell, one shaded cell can absorb the power of many other cells in the string, disproportionately affecting panel output.

Lightly doped p-type regions pose a problem, as the resulting contact has too high a resistance for a good ohmic contact, but too low a forward voltage and too high a reverse leakage to make a good diode.

The transistor is designed so that its collector saturation voltage ( ) is less than the base emitter voltage ( roughly 0.6 V ) minus the Shottky diode's forward voltage drop ( roughly 0.2 V ).

In GaAs the mobility or drift velocity in the third band is lower than that in the usual conduction band, so with a small increase in the forward voltage, more and more electrons can reach the third band and current decreases.
