摘要： A paste composition for forming an electrically conductive layer on a p-type silicon semiconductor substrate comprises aluminum powder, an organic vehicle and powder of at least one inorganic compound selected from a group consisting of an oxide-based inorganic compound and a non-oxide-based inorganic compound. The oxide-based inorganic compound has a thermal expansion coefficient smaller than the thermal expansion coefficient of aluminum and a melting temperature, a softening temperature and a decomposition temperature each higher than the melting point of aluminum. The non-oxide-based inorganic compound has a thermal expansion coefficient smaller than the thermal expansion coefficient of aluminum and at least one of a melting temperature, a softening temperature or a decomposition temperature higher than the melting point of aluminum. A solar cell comprises an electrically conductive layer formed by applying the paste composition having the aforementioned characteristics onto a p-type silicon semiconductor substrate and thereafter firing the paste composition.
