Is a solar cell a direct energy conversion device and if so

Is a solar cell a direct energy conversion device and if so, exactly how is it a direct energy conversion device? If it is not a direct energy conversion device then explain exactly why it is not.

Solution

yes, solar cell is a direct eergy conversion device.

solar cells directly convert sunlight to electricity. and it provide the most cost-effective source of electricity.

-Most solar cells are made of crystalline and amorphous silicon materials.

- When sunlight strikes the solar cell, part of the light spectrum imparts enough energy to create electron-hole pairs in the semiconductor material.

-A potential barrier in the cell is set up by forming a junction between dissimilarly-doped semiconductor layers. This separates the light-generated carriers resulting in an induced voltage of about 1/2 volt. The available current is a function of cell area and light intensity.

-The electricity is collected and transported by metallic contacts placed on both surfaces of the cell.

-solar cells are formed into modules by connecting them in series and parallel in order to get more current and voltage.

-For even greater power, these cells can be interconnected in larger groups to form arrays. The dc electricity generated by the solar cell array is usually passed through a power conditioner for voltage and power regulation, and conversion to alternating current.
