Solar energy can be directly converted into electrical energy by a photoelectric cell. Here's a step-by-step explanation:

1. Solar energy is the energy we get from the sun. This energy comes in the form of solar radiation, which makes the production of solar electricity possible.

2. A photoelectric cell, also known as a photovoltaic cell, is a device that converts light energy, not just solar, into electrical energy through the photoelectric effect.

3. The photoelectric effect is a phenomenon in physics. The theory of this effect was developed by Albert Einstein. When light shines on the cell, it can transfer energy to certain materials. This energy transfer can cause electrons to move, creating an electric current.

4. This electric current can then be used as electricity. In this way, a photoelectric cell can convert solar energy directly into electrical energy.

5. Dry cells, rechargeable cells, and batteries can store and provide electrical energy, but they do not convert solar energy into electrical energy directly. They need to be charged with electricity that could be generated by a photoelectric cell.

So, the correct answer to your question is c. photoelectric cell.
