Abstract: The present disclosure discloses a lithium and tellurium-silicate binary glass-oxide-complex system and a conductive paste containing the complex system, and belongs to the technical field of solar cells. The present disclosure uses a “functional modularity” strategy in the formula design of a glass-oxide-complex system (GOC). Alkali metal ions with high migration and reactivity are separated from a glass body with high fluidity, thus a binary complex system is constructed, that is, a lithium-containing glass-oxide-complex (Li-GOC) with high activity and a tellurium-silica-containing glass-oxide-complex (Si—Te-GOC) with high fluidity. Through the modularized formula strategy, active ingredients can be better controlled, so as to obtain more balanced contact and open circuit voltage and improve the photoelectric conversion efficiency of a solar cell.

Abstract: A method is provided for role-oriented risk analysis in a contract. The method generates, using deep semantic association analysis, a report specifying a set of potential risks relating to explicit and hidden roles of contract parties. The generating step categorizes input statements of the contract into respective obligation/right pairs according to a deep semantic association distribution thereof. Each pair includes a respective obligation and a respective right. The generating step detects deep semantic differences between the respective pairs and a set of reference obligation/right pairs. The generating step identifies the explicit and hidden roles of the involved parties in the respective obligations/rights pairs according to domain-specific use scenarios and multidimensional local and global context clues in the contract. The generating step identifies the set of potential risks by applying a deep semantic role-oriented risk entailment model to the deep semantic differences.
