US physicists overcame a significant barrier to the commercialization of solar cells made with halide perovskites as a less expensive, more efficient alternative to silicon when harnessing solar energy.
High-efficiency and inexpensive solar cells are certain features guaranteed by perovskite semiconductors.
Due to their effectiveness at converting sunlight into electricity, perovskite solar cells have attracted a lot of research interest as a potential replacement for conventional silicon-based solar cells.
A leading laboratory in photonics and renewable energy at the University of Ottawa has developed a new method for measuring the solar energy produced by bifacial solar panels, the double-sided solar technology which is expected to meet increased global energy demands moving forward.
Recent research published on December 21st, 2022, in the Energy Material Advances journal outlines the degradation mechanisms and examines the interfacial engineering focusing on their impacts on flexible perovskite solar cells.
When exposed to sunlight, perovskite solar cells degrade, resulting in decreased performance over time.
Once again, HZB maintains the world record for tandem solar cells, which combine a silicon bottom cell with a perovskite top cell. A total of 32.5% of the incident solar radiation is converted into electrical energy by the new tandem solar cell.

Bifacial thin film solar cells constructed from copper indium gallium diselenide, or CIGS, may gather solar energy from both their front and back sides, possibly yielding more solar energy than traditional equivalents. However, so far, their development has resulted in very moderate energy conversion efficiency.
Solar cells will be crucial in the global switch to renewable energy as the movement toward carbon neutrality gains momentum and as a concerning pattern of rising temperatures and natural disasters brought on by global warming persists.
