PURPOSE:To obtain an amorphous solar cell, whose close contact property is excellent and whose reliability regarding its preservation has been enhanced, with good reproducibility and at a low cost by a method wherein a silane coupling agent is laid at least on a boundary face between a light-transmitting face and a thick-film electrode. CONSTITUTION:In an amorphous solar cell obtained after a thick-film electrode formed by dispersing a conductive material powder in a binder resin is formed on a light-transmitting face of a solar cell unit, a silane coupling agent is laid at an interface between at least the light-transmitting face and the thick-film electrode. The silane coupling agent is provided with the following in an identical molecule: an organic functional group having a substitution group which reacts with an organic material; a hydrolytic group which reacts with an inorganic material. Accordingly, the coupling agent is bonded chemically to an amorphous silicon film and the conductive material powder; it is bonded chemically to also a resin in the thick-film electrode; the adhesion between the both and mechanical strength are enhanced. In addition, since the thick-film electrode is formed, this solar cell can be formed at a low cost and its productivity can be enhanced.
