A more attractive type of solar cell could make the renewable energy far more efficient than it has ever been. While there have been reports of California generating too much solar energy, just imagine if solar panels could convert more of the sun they collect into usable electricity. Perovskite cells, which is a hybrid form of photovoltaic cells, are an alternative to silicon that are cheaper to produce and could end being much more efficient on a regular basis.
South Korea’s Ulsan National Institute of Science and Technology (UNIST) was able to set a new record of 22.1 percent efficiency with a stabilized, small perovskite solar cell. This level of efficiency was reached last year, but that wasn’t on a regular basis.
The team also achieved 19.7 percent efficient with cells measuring at one square meter. The prior record for a stabilized perovskite solar cell was set at 21.2 percent by a collaborative effort between UNIST and the Korea Institute of Chemical Technology (KRICT).
