Solar cells are semiconductor-based devices primarily, which convert sunlight directly to electrical energy through the photovoltaic effect, which is the appearance of a voltage and current when light is incident on a material.The photovoltaic effect was first reported by Edmond Becquerel in 1839, who observed a voltage and current resulting …
A solar cell is an electronic device which directly converts sunlight into electricity. Light shining on the solar cell produces both a current and a voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy state, and secondly, the movement of this ...

In other words, if the voltage of your battery (the load) is higher than that of your solar panel, then your solar charge controller will not allow the current to flow from your solar panel back to your battery to charge it because the circuit is open. Thus, your display will indicate that your solar panel has voltage but no amps.
Photovoltaic cells convert sunlight into electricity.

When the batteries in an off-grid system are fully charged and PV production exceeds local loads, an MPPT can no longer operate the panel at its maximum power point as the excess power has no load to absorb it. The MPPT must then shift the PV panel operating point away from the peak power point until production exactly matches …
If a solar panel is exposed to sunlight but is not plugged in to anything--dc load, inverter, etc--where does that electricity go? In this example, I''m assuming the solar exposure is still freeing electrons, but where do they go?

For it to be actual electricity there must be both voltage and current. With the load disconnected you have voltage (i.e. potential) but no current. Since the charge carriers liberated by the incoming light energy have nowhere to go, an equilibrium is developed in the panel. So where does the energy go?

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).
Fig. 3. An electronic load can be configured for solar-cell testing using a dc offset supply. Typically, the offset supply is set to 3 V to ensure that the load''s minimum voltage requirement is always met. The voltage from dc source will have no impact on the solar cell, which is a floating device; it merely biases the solar cell up by 3 V.
