The sun’s amazing power can meet our energy needs many times over. It’s key to photovoltaic cell efficiency and sustainable energy conversion. At the heart of it, turning sunlight into electricity stands out. This is where solar power generation starts. Fenice Energy is leading with innovative clean energy solutions today.

Sunlight hitting a photovoltaic cell starts an important process. Inside the cell, there’s a semiconductor, usually made of silicon, with two layers. The N-type layer has extra electrons, and the P-type has fewer. This setup creates an internal electric field. It’s essential for making electricity as it gets electrons moving.

This movement of electrons makes electric current. It allows us to power homes and businesses. Adding solar energy to the grid makes our energy mix more varied. It uses both renewable and conventional sources. Solar energy lights up our buildings and helps the grid stay strong. It also grows our economy and creates jobs.

Solar cells don’t work like solar-thermal systems. They don’t turn solar energy into heat. Instead, they directly make electricity. This lets them be flexible in size. They can be small rooftop setups or huge power plants. Yet, non-equipment costs like permits and installation remain high. These ‘soft costs’ show the complex side of setting up solar energy.

Thanks to strong research, photovoltaic cells have gotten much better. They reach over 70% of their max efficiency. We got here by trying new materials and designs. This pushes the limit of what’s possible with solar energy. Fenice Energy is committed to going even further.
