With reference to technology for solar power production, consider the following statements:
1. ‘Photovoltaics’ is a technology that generates electricity by direct conversion of light into electricity, while ‘Solar Thermal’ is a technology that utilizes the Sun’s rays to generate heat which is further used in electricity generation process.
2. Photovoltaics-generates Alternating Current (AC), while Solar Thermal generates Direct Current (DC).
3. India has manufacturing base for Solar Thermal technology, but not for photovoltaics.
Select the correct answer using the code given below:
Explanation
Statement 1 is correct: Photovoltaic devices generate electricity directly from sunlight using PV cells made up of semiconductors. Photovoltaic devices convert optional radiation into electricity. Several solar thermal systems can collect and transform radiant energy recieved from the sun into High temperature thermal (heat) energy which can be used directly or converted into electricity.
Statement 2 is incorrect: Solar energy can be converted directly into electrical energy by photovoltaic cells commonly called solar cells.
Statement 3 is incorrect: India has a manufacturing base for Solar thermal technology as well for Photovoltaics.
