Abstract
A powder glass solution is applied on top of a solar cell 12 with electrodes 17 formed thereon, and solvent is volatilized, followed by baking process, by which a glass 13 is directly formed on the top of the solar cell 12. In this way, the alignment between solar cell and glass as well as the finish work of removing overflowed adhesive are eliminated. Also, by selecting a powder glass having a coefficient of thermal expansion generally similar to that of a P-type silicon substrate 14, distortion by heating due to abrupt temperature changes is reduced. Thus, cost reduction and reliability improvement can be fulfilled.
