Their efficiency jumped from 3% in 2009 to over 25% in 2020. Still, materials must balance efficiency, cost, and lifespan to be effective.
- Perovskite solar cells are promising due to their fast-growing efficiency.
- Organic PV cells cost less to make but are less efficient than silicon ones.
- Quantum dot solar cells are easy to make but not very efficient.
- Multijunction solar cells are super efficient but hard to make and expensive.
- Concentration PV cells use lenses to focus light and are highly efficient.
Compared to new tech, traditional silicon solar cells make 0.5 to 0.6 volts. They are key to solar power. Fenice Energy focuses on these essential components and how to integrate them into strong systems.

Solar cell costs have dropped a lot since the first practical cell in 1954. Solar cells went from powering satellites in the 1960s to being key in renewable energy. Fenice Energy has grown to lead in clean energy thanks to this progress.
Understanding Photovoltaic Cell Efficiency and Bandgaps
The push for solar power is growing, thanks to better photovoltaic cell efficiency. This efficiency depends on the materials used and how they interact with light. Silicon is the most popular choice, making up about 95% of the market. It’s durable and keeps over 80% of its power even after 25 years. But to make solar power cheaper and more efficient, scientists are looking at other materials like cadmium telluride and multijunction cells.
Cadmium telluride is cheaper to make than silicon but doesn’t work as well. On the other hand, copper indium gallium diselenide cells could do better if it wasn’t so hard to mix four different elements together.
- Perovskite solar cells have made huge leaps, from just 3% efficiency to 25% in a little over ten years.
- Quantum dot solar cells can be adjusted to absorb more light and work better when paired with other types of cells.
- Organic PV cells aren’t as efficient as traditional ones, but they could be cost-effective if produced on a large scale.
In India, where coal still dominates electricity production, there’s a big interest in solar power. Moving to solar needs strong policies and advances in technology.
Fenice Energy has spent over 20 years working on making solar more efficient. They focus on improving cell efficiency and understanding the materials used in solar panels.
