Patent number: 10290432Abstract: To fabricate a perovskite solar cell (PSC), a printable carbon electrode is formed on an uppermost layer, either a perovskite layer or an interface layer thereon, of a partially-completed PSC. A carbon ink is first prepared by dispersing carbon materials in a mixture of a polymer binder and a solvent. Then the carbon ink is screen-printed on the uppermost layer to form a wet film thereon. The wet film is baked with a baking temperature not exceeding 100° C. to evaporate the solvent to form the carbon electrode. Advantageously, the wet film is pressed with a pressure during baking such that the carbon electrode becomes denser and yields a lower sheet resistance when compared to one formed without being pressed. Preferably the pressure is at least 16,000 Pa. Experimental results show that the percentage reduction of sheet resistance can reach 40%.Type: GrantFiled: February 13, 2018Date of Patent: May 14, 2019Assignee: Nano and Advanced Materials Institute LimitedInventors: Qian Li, Chao Cai, Qingdan Yang, Jia Li, Paul Kwok Keung Ho

Patent number: 10216805Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for dynamically generating and configuring pre-aggregated datasets optimized for responding to particular types of data requests made against a large sub-optimal multidimensional dataset are disclosed. A dynamic aggregator monitors the query types and response latencies associated with queries made against the large multidimensional dataset. The dynamic aggregator defines pre-aggregated datasets based on the types of queries received from users and calculates a respective benefit score for each pre-aggregated dataset. The benefit score of each pre-aggregated dataset can be based on the recorded latencies and query count for the pre-aggregated dataset. The dynamic aggregator can decide whether to generate and/or maintain particular pre-aggregated datasets based on the current values of the benefit scores associated with the particular pre-aggregated datasets.Type: GrantFiled: August 11, 2016Date of Patent: February 26, 2019Assignee: Google LLCInventors: Chao Cai, Eric W.
