Name three processes involved in the formation of solar cell.

Explanation

To answer the question regarding the three processes involved in the formation of a solar cell, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Generation of Electron-Hole Pairs**:
- The first process in the formation of a solar cell is the generation of electron-hole pairs. When photons from sunlight strike the solar cell, they impart energy to the electrons in the semiconductor material (typically silicon). This energy allows some electrons to break free from their atomic bonds, creating free electrons and leaving behind holes (the absence of an electron).

2. **Separation of Charges**:
