Solar cells
Solar cells, also known as photovoltaic cells, are devices that convert sunlight directly into electricity using the photovoltaic effect. They are made from semiconductor materials like silicon, which absorb photons from sunlight and generate an electric current. Solar cells play a crucial role in renewable energy production by harnessing solar radiation to generate clean electricity without emissions. They are widely used in solar panels for residential, commercial, and industrial applications, contributing to sustainable energy solutions and reducing reliance on fossil fuels. Ongoing research focuses on improving efficiency, durability, and affordability to accelerate the adoption of solar energy globally.

Application
Hydrogen
Hydrogen plays a pivotal role in fuel cell technology, offering a clean and efficient energy source. Fuel cells convert hydrogen and oxygen into electricity and water, emitting only heat as a byproduct. Hydrogen is produced through various methods, including electrolysis of water using renewable electricity or steam reforming of natural gas. Efficient and scalable hydrogen generation is essential for widespread adoption. Hydrogen storage remains a key challenge due to its low density and high volatility. Research focuses on developing safe and compact storage solutions, such as metal hydrides and carbon-based materials. Advancements in hydrogen technology hold promise for decarbonizing transportation and energy sectors.
