Patent ID: 8853523

Claim:
A method of manufacturing a solar cell module having a plurality of photovoltaic cells electrically connected by connectors, comprising forming an antireflective film on a light receiving surface side of the photovoltaic cells, wherein the forming of the antireflective film includes: forming an antireflective film raw material containing a glass component, an organic solvent, and silica particles on one of surfaces of a transparent member, by heating while support pins make contact with another surface of the transparent member at an interval, forming in the transparent member low temperature regions to partially dissipate heat from the transparent member via the support pins and high temperature regions between the low temperature regions to remove the organic solvent from the antireflective film raw material by temperature rise of the transparent member to form an antireflective precursor that is thinner in the low temperature regions than a thickness in the high temperature regions and has a curved shape depressed towards the transparent member at the thinner portion, and forming the antireflective film on the one surface of the transparent member by heat treatment of the antireflective precursor.
