IV curves of solar cells in parallel and series

When 2 solar cells are in parallel, is it that the final IV curve is the simple addition of voltages No, when two devices (solar cells or anything else) are in parallel, the voltages are equal and ...

How does one manufacture a P-N junction?

Modern devices rely on epitaxy, both in Silicon and in III-V materials (GaAs, InP, InAs, GaSb, including GaN, SiC). As you listed, ingots are cut into substrates with certain doping type. Then, to ...

What is voltage in I-V curve of a solar cell?

The effect of illuminating the surface of the n region consists in the generation of electron-hole pairs fired towards the depletion region. This phenomenon is equivalent to an independent current ...

What is voltage in I-V curve of a solar cell?

why is the voltage changing in an I-V curve? You apply a variable load to get a current flow. Without a current flow, you can't produce an I-V curve. To make a useful I-V curve, the current flow will ...

Confusion regarding solar cell?

Out by the knee of the curve, the PVs may be able to supply enough power to overcome friction, but without some clever electronics, this power would be delivered with relatively low current and ...

Solar charging in northern urban environment - boost mode needed?

Is there anything one should do differently designing a charger optimized for such an environment compared to a general purpose solar charger? Yes. Unless you have a mad desire to charge those ...

Solar charging in northern urban environment - boost mode needed?

The most important is to reduce power consumption of your load as much as possible. "About 1W" sounds like a wet-finger-in-the-wind estimation. In this scenario where you need to guarantee ...

Solar charging in northern urban environment - boost mode needed?

The maximum power point of a solar cell depends on the amount of light it receives (called "insolation", which is neither a typo for "isolation" nor for "insulation"). ...

Is this solar circuit connection OK?

You'll need to at least be able to check the balance between your battery banks, and stop the inverter's use of them if either drop below 44 V, even if you intervene manually to correct any imbalance. ...
