Photovoltaics
Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels.

Renewables
Solar PV is today the only renewable energy technology on track with the Net Zero Emissions by 2050 (NZE) Scenario. Wind, hydro, geothermal, solar thermal and ocean energy use needs to expand significantly faster in order to get on track. Non-bioenergy renewables need to increase their share of total energy supply from close to 5% today to approximately 17% by 2030 in the …
