How It Works ยท Science
Solar Photovoltaics
Light to electricity conversion
Solar PV uses semiconductor junctions where light excites electrons creating current collected by contacts.

Inputs
Sunlight hitting semiconductor layers in PV cells.
Process
Photons free electrons; junction creates voltage; wiring carries DC power to an inverter.
Outputs
Usable AC electricity after inversion and grid-tie or storage.

Why it matters
Climate Resilience
Climate resilience reduces damage from climate-related hazards and speeds recovery.
Comparison
Mitosis vs Meiosis
Mitosis makes matching cells for growth and repair, while meiosis creates sex cells and introduces genetic variation.
Examples
Osmosis
Osmosis is water diffusion through a semipermeable membrane toward higher solute concentration.
