What is solar photovoltaics (PV)?
Solar photovoltaics (PV) employs the photovoltaic effect to produce electricity from solar radiation. A major milestone in the history of solar PV technology is the first demonstration of a practical silicon photovoltaic (PV) cell, at Bell Laboratories in 1953 (Perlin 2004 ), that converted solar energy into electricity.
What is the photovoltaic effect?
The photovoltaic effect is defined as the process that generates either voltage or current when the device (or solar cell) is exposed to a light source of a suitable wavelength. Solar photovoltaics (PV) employs the photovoltaic effect to produce electricity from solar radiation.
What is the manufacturing process of PV solar cells?
The manufacturing of PV solar cells involves different kinds of hazardous materials during either the extraction of solar cells or semiconductors etching and surface cleaning (Marwede et al., 2013; Üçtuğ and Azapagic, 2018).
Are DSSC and perovskite solar cells the future of PV?
While Si and thin-film PV technologies have shown tremendous growth in terms of their installations, owing to their cost advantages, emerging PV technologies such as DSSC and perovskite solar cells (PSC) have the potential to reach the commercial market and compete with Si and thin-film PV technologies.
Is solar PV a green technology?
Still, solar PV technology is deemed a green technology and can significantly contribute to addressing climate challenges. However, more studies are required to understand the emerging PV technologies' environmental impacts and life cycle, mainly based on PSCs.
What are the different types of PV technology?
Since then, different PV technologies have emerged, including silicon PV, thin-film PV, dye-sensitized PV, perovskite PV, etc. (Amin et al. 2017 ). The classification of these technologies (or devices) is based on the absorbing film (or active layer) used in the PV cell.
