The generation of current in a solar cell, known as the "light-generated current", involves two key processes. The first process is the absorption of incident photons to create electron-hole pairs. Electron-hole pairs will be generated in the solar cell provided that the incident photon has an energy greater than that of the band gap.
Semiconductors in PV cells absorb the light’s energy when they are exposed to it and transfer the energy to electrons. The absorbed additional energy allows electrons to flow in form of an electrical current through the semiconductor material.
The first thing is the direction of photocurrent flow. The electric current that flows as a result of light is actually in the opposite direction of the normal diode current. Normally current (defined as the movement of positive charge) moves from the anode to the cathode in a diode.
When the semiconductor is exposed to sunlight, it absorbs the light, transferring the energy to negatively charged particles called electrons. The electrons flow through the semiconductor as electrical current, because other layers of the PV cell are designed to extract the current from the semiconductor.

In semiconductors, current is often schematized as being carried either by the flow of electrons or by the flow of positively charged "holes" in the electron structure of the material (in both cases only electron movements are actually involved).
Silicon and gallium are the two most widely used semiconductor materials in solar cells, accounting for over 90% of the global PV market. Semiconductors in solar cells absorb the energy from sunlight and transfer it to electrons, allowing them to flow as an electrical current that can be used to power homes and the electric grid.
Each absorbed photon generates an additional electron–hole pair, and this effect adds to the thermally induced generation current. This unbalances the diffusion current, causing a current to flow for a short time, which modifies the electric charges and thus the internal electric field, until the two currents cancel each other out again.
These pairs create a flow of current that follows the built-in potential slope of the material. Solar cells have emerged as an important alternative power source, especially since the oil crises in the 1970s. …
