Efficiency Improvements
Modern research has led to efficiency improvements in PV cells through:

Multi-Junction Cells
Layers of different semiconductor materials capture more of the solar spectrum.

Perovskite Solar Cells
A new material promising high efficiency and low production costs.

Bifacial Panels
Capture sunlight from both sides, increasing energy yield.
Energy Storage & Grid Integration
Solar energy is intermittent, so effective storage and grid solutions are essential:

Battery Storage (e.g., Lithium-Ion, Flow Batteries)
Store excess energy for later use.

Smart Grid Systems
Enable efficient distribution and integration of solar power.

Microgrids
Allow localized energy production and consumption.
Durability and Environmental Considerations
Improved Materials
Anti-reflective coatings, tempered glass, and better encapsulation enhance lifespan.
Recycling Initiatives
Strategies to recycle and repurpose old PV panels.
