6 FAQs about [Solar power generation photovoltaic effect theory]

What is the photovoltaic effect?

What is the photovoltaic effect in organic materials?

Until the beginning of twenty-first century, the photovoltaic effect in organic materials did not look very exciting due to the low mobility of charge carriers and strong trapping of the excitons before their separation in the heterojunction. This resulted in rather small external quantum efficiency (EQE) and energy conversion (< 1%).

What is photovoltaic technology?

Who discovered the photovoltaic effect?

The photovoltaic effect was discovered for the first time by E. Becquerel in 1839, using an electrochemical cell . The process of conversion of light to electricity is called the photovoltaic effect. It simply means the production of DC current from sunlight as depicted in Fig. 1.8.

Where does the photovoltaic effect occur?

The photovoltaic effect occurs in solar cells. These solar cells are composed of two different types of semiconductors - a p-type and an n-type - that are joined together to create a p-n junction. To read the background on what these semiconductors are and what the junction is, click here.

What is the difference between photoelectric effect and photovoltaic effect?

The main distinction is that the term photoelectric effect is now usually used when the electron is ejected out of the material (usually into a vacuum) and photovoltaic effect used when the excited charge carrier is still contained within the material.
