Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

Developed by Tsutomu Miyasaka in 2009, perovskite solar cells emerged as a breakthrough in photovoltaics and a promising alternative to traditional solar technologies. The world’s most advanced labs ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was ...

The research advanced the durability of perovskite solar cells without compromising their exceptional efficiency, moving closer to a practical, low-cost alternative to silicon-based photovoltaics.

A group of scientists from Chinese solar module maker Longi has described in a new scientific paper the 27.81%-efficient hybrid interdigitated back-contact (HIBC) solar cell it unveiled in April 2025.

Topics include accelerating beyond module assembly to promote investment and creation of new wafer and cell capacity in the U.S. Figure: Ownership and location of factories producing solar cells for ...

High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard ...

Imagine two homes on the same street, with the same-sized roofs, both fitted with solar panels. Yet one home consistently generates more electricity than the other. The difference comes down to solar ...
