Solar cells based on perovskites, a versatile class of materials with promising optoelectronic properties, are gradually making their way toward commercialization. While these solar cells can have notable advantages over existing solar cell designs, including higher...
Recent efforts aimed at developing more advanced battery technologies have in great part focused on designing novel cathode materials. This is because existing cathodes do not perform well at high voltages and can contribute to the rapid loss of battery capacity.
Lithium-metal batteries could exhibit significantly higher energy densities than lithium-ion batteries, which are the primary battery technology on the market today. Yet lithium-metal cells also typically have significant limitations, the most notable of which is a...
To reduce carbon emissions and mitigate climate change on Earth, governments and companies worldwide have been investing in the electrification of both public transport and private vehicles. China is among the countries that started exploring the electrification of...
Wireless internet supports the daily activities of countless people worldwide, ranging from their professional communications to internet browsing and the streaming of movies or TV series. This spiking demand for wireless internet access goes hand in hand with greater...
In recent years, engineers and scientists worldwide have been working on new technologies for generating electricity from renewable energy sources, including photovoltaics (PVs), wind turbines and hydro-power generators. An alternative solution for mitigating the...
If an individual solar cell is shaded and other cells in the same module are not, the sunlit cells can try to drive current through the shaded cell, resulting in an increase in temperature and potential damage to the cells. These conditions put the shadowed cell under...
The power-conversion efficiencies (PCEs) of organic solar cells based on compounds known as polymer donors and fused ring electron acceptors (FREAs) have recently exceeded 19%. In contrast, organic solar cells based on non-fused ring electron acceptors (NFREAs), more...
In recent years, engineers have introduced a wide range of photovoltaic (PV) solutions that could facilitate the sustainable generation of electricity worldwide. These include organic solar cells (OSCs), PV devices that use organic molecules or polymers to convert...
High-capacity lithium-ion batteries (LIBs) could play a crucial role in the electrification of vehicles and other large electronics. To successfully deploy these batteries on a large scale, however, engineers will first need to ensure that they can safely operate at...
