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...
Hydrogen fuel cells, devices that can convert the chemical energy stored in hydrogen into electrical energy via an electrochemical reaction, are promising solutions for electrifying large vehicles. Fuel cells based on low-temperature (under 100 °C) proton exchange...
Ethylene (C2H4) is a highly flammable compound widely used in numerous settings, including the manufacturing of packaging and plastic-based items, the chemical industry, agriculture and health care. Developing effective and sustainable methods to produce ethylene on a...
The electrification of road vehicles has already begun, with most automotive companies now investing in hybrid and electric cars. While these efforts could contribute to reducing carbon emissions worldwide, they have so far been primarily focused on cars, rather than...
Energy researchers have been trying to understand the implications of a transition to fully renewable energy for decades. Some past studies suggested that technologies to generate energy from renewable energy sources, such as solar panels and wind turbines, might not...
The development of technologies to generate affordable electricity and their deployment in remote or developing geographical regions has been the topic of many recent studies. These studies could inform future interventions and policies in these regions, by...
