    摘要： The present invention provides an aluminum paste for solar cells in which a reduction in conversion efficiency of solar cells is suppressed in spite of the presence of silicon. Specifically, the present invention provides an aluminum paste for solar cells, containing aluminum, silicon, and strontium, wherein when the total mass of the aluminum, silicon, and strontium is defined as 100 mass%, the content of the silicon is 1 mass% or more and 60 mass% or less, the content of the strontium is 0.001 mass% or more and 10 mass% or less, and the remainder is the aluminum.
