Four-terminal tandem perovskite/CIGS solar cell with 25.5% efficiency
Researchers in China have developed a four-junction tandem perovskite/CIGS cell. They claim it is the most efficient device of its kind with an n-i-p structure thus far. They used a novel surface passivation strategy to improve the perovskite cell efficiency and fill factor.

Tandem tin-lead perovskite solar cell with 25.5% efficiency
The US National Renewable Energy Laboratory has made a tandem perovskite solar cell that can retain 80% of its original efficiency after 1,500 hours of continuous operation, or more than 62 days. To improve its stability, they used a hole-transporting material made of phenethylammonium iodide and guanidinium thiocyanate.
Vehicle integrated solar to power refrigerated trailers
German VIPV specialist Sono Motors has signed an agreement with French refrigerated vehicle supplier Chereau to develop refrigerated vehicles powered by an integrated solar array. The two companies will build and test a prototype vehicle, and begin to evaluate mass production. Sono estimates that the concept could save around 3,400 liters of fuel and avoid 9 tonnes of CO2 emissions per vehicle, per year.
