Are silicon-based photovoltaic panels a Socioenvironmental threat to the biosphere?

Mass installation of silicon-based photovoltaic (PV) panels exhibited a socioenvironmental threat to the biosphere, i.e., the electronic waste (e-waste) from PV panels that is projected to reach 78 million tonnes by the year 2050.

What are the technical challenges for the industrialization of PV systems?

Critical technical challenges for the industrialization of PV systems are performance, reliability, and manufacturability. Developing high efficiency, cost-effective, and large-scale adaptability of PV panels with longer life opens enormous opportunities for innovation.

How to improve photoelectric efficiency and lifespan of a PV cell?

To improve the PV cell’s photoelectric efficiency and lifespan, two crucial external factors need consideration: First, during operation, the overall temperature of the PV cell rises, causing a decrease in open-circuit voltage and a moderate increase in short-circuit current, resulting in reduced power output.

Why do we need silicon solar cells for photovoltaics?

Photovoltaics provides a very clean, reliable and limitless means for meeting the ever-increasing global energy demand. Silicon solar cells have been the dominant driving force in photovoltaic technology for the past several decades due to the relative abundance and environmentally friendly nature of silicon.

Can cool PV modules improve conversion efficiencies?

Researchers, worldwide developed approaches to cool PV modules and conducted experimentatal and simulation studies to estimate their potential in improving the PV conversion efficiencies such as (Hasanuzzaman et al., 2016) and (Reddy et al., 2015).

What are the daytime temperature variations of PV panels with hygroscopic hydrogels?

The daytime temperature variations of PV panel with different hydrogels are illustrated in Fig. 3 h-k. it can be observed that, the temperatures of these PV panels cooled by the hygroscopic hydrogels are all significantly lower than that of the PV panel without the hydrogel.
