In a joint project with Prof. Yang, the engineers showed a four-terminal perovskite-CIGS tandem solar cell. It is based on a perovskite top cell that has actually been maximized for assimilation with Midsummer's CIGS cells that are made use of in their commercial suite of BIPV products.

Amid every one of the efforts to transform the country's power supply to renewable sources, solar energy still accounts for a little less than 3% of electrical energy generated in the united state. Partly, that's because of the fairly high cost to produce solar cells.

Materials researchers at the UCLA Samueli School of Engineering as well as colleagues from five other universities all over the world have discovered the significant reason that perovskite solar cells-- which show excellent assurance for improved energy-conversion performance-- degrade in sunlight, causing their performance to suffer over time.

UCLA materials scientists and also associates have actually discovered that perovskites, a class of encouraging materials that could be utilized for low-priced, high-performance solar cells and also LEDs, have a previously unutilized molecular part that can additionally tune the digital home of perovskites.
