Understanding the Voltage – Current (I-V) Curve of a Solar Cell
The operating point (I, V) corresponds to a point on the power-voltage (P-V) curve, For generating the highest power output at a given irradiance and temperature, the operating point should such correspond to the maximum of the (P-V) curve, which is called the maximum power point (MPP) defined by (Impp* Vmpp).
In theory, a huge amount. Let''s forget solar cells for the moment and just consider pure sunlight. Up to 1000 watts of raw solar power hits each square meter of Earth pointing directly at the Sun (that''s the theoretical power of direct midday sunlight on a cloudless day—with the solar rays firing perpendicular to Earth''s surface and giving …
