A semiconductor structure for optical power conversion and a method of forming the semiconductor structure are provided. In an aspect, the method may include removing a first portion of the semiconductor structure from a first region, wherein the semiconductor structure comprises a layered photovoltaic structure on a silicon-on-insulator structure. A second portion of the semiconductor structure may be removed from a second region, wherein the second region is located adjacent to the first region, and wherein an insulator layer of the silicon-on-insulator structure is exposed by the removed second portion. A passivation layer pattern may be formed over the semiconductor structure. Electrodes may be formed on portions of the surfaces of the semiconductor structure that are uncovered by the passivation layer.

Search query result set count estimation is described. A system parses data set query that includes first query attribute and second query attribute. The system identifies first hierarchy of connected nodes including a first node representing a first query attribute, and a second hierarchy of other connected nodes including a second node representing a second query attribute. The system identifies a directed arc connecting first correlated node in first hierarchy to second correlated node in second hierarchy. The system identifies cross-hierarchy probabilities of correlations between values of a first attribute represented by the first correlated node and values of a second attribute represented by the second correlated node. The system outputs query result set estimated count generated from cross-hierarchy probabilities, probabilities that values of first attribute are associated with values corresponding to first node, and probabilities that values of second attribute are associated with values corresponding to second node.
