How does solar energy generate electricity?

As source of electricity generation, Fig. 9.1 Power generation from solar energy by region (in TWh). (Authors’ own L. EICKE ET AL. this eld induces a direct electrical current. This process is known as the pho- tovoltaic effect. Electricity generation exploiting this effect is not only possible cells also generate electricity with cloudy skies.

Will solar power be the world's largest source of electricity by 2050?

The Global PV market is fast growing with forty times the installed capacity it was ten years ago. Solar PV is currently responsible for contributing at least 1% to electricity generation worldwide. The International Energy Agency (IEA) envisages that solar power will be the world's largest source of electricity by 2050.

Are photovoltaics a viable alternative to conventional power generation?

Additionally, photovoltaics' improved efficiency and production cost competitiveness have positioned them as mature alternatives compared to conventional power generation facilities . Therefore, there are two major plans to expand the solar energy supply globally .

What is a photovoltaic system?

Photovoltaic systems have long been used in specialized applications as stand-alone installations (island systems). Grid-connected PV systems were first constructed in the 1990s. Nowadays, solar energy for electricity generation is applied on the wide range between small roof-top PV systems and large utility scale solar parks.

Will solar PV become the world's largest technology by 2035?

According the World Energy Outlook of the International Energy Agency, solar PV may become the largest technology in terms of global installed capacity in the Stated Policies Scenario by 2035 (IEA 2019 ). Power generation from solar energy by region (in TWh). (Authors’ own elaboration, data from IRENA 2020)

How does a solar power plant work?

Instead, mirrors are used to focus solar rays to heat a fluid. Similar to conventional power plants, the thermal energy then drives a turbine to generate electricity. A downside of the CSP technology is that direct radiation is required for the process, because diffuse radiation cannot be focused.
