Abstract
A powder glass solution is applied on top of a solar cell with electrodes formed thereon, and solvent is volatilized, followed by baking process, by which a glass is directly formed on the top of the solar cell . 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 , distortion by heating due to abrupt temperature changes is reduced. Thus, cost reduction and reliability improvement can be fulfilled.
