Trimming optical losses in tandem perovskite cells

Spanish researchers have unveiled a monolithic nano-structured perovskite silicon tandem device they claim can reduce optical losses by more than a third compared to planar perovskite cells of the same kind.

Japanese scientists trial printing on perovskite

Researchers from three Japanese universities have developed a process based on inkjet printing they say could reduce the cost of perovskite solar cell production. The group fabricated small cells with efficiencies as high as 13.19%, a figure they claim is promising enough to offer the possibility of scaling up to commercial production.

It’s all in the electrons – Japanese scientists give perovskites a push

Scientists at the Okinawa Institute of Science and Technology have developed a process for the creation of perovskite cells with better than 20% efficiency. The cells use a tin-oxide electron transport layer, which the scientists say can triple their operational lifetime.

Researchers turn to spray coating in applying ETL to perovskites

Perovskites, a tempting low-cost alternative to crystalline silicon based solar cells, could be moving closer to commercial production thanks to a new way of applying the critical electron transport layer (ETL) pioneered by an international team of researchers.
