An internet communication system, which is provided with session managing serversand. In the system, each session managing server manages wireless communication apparatusesandand call relay serversand. For that reason, the processing load of each session managing server is allowed to be equalized. As a result, the operational efficiency of the system may be enhanced, and quality of services offered to the user of the system may be improved.

A water-repellent layer is formed on a light-receiving surface of a solar battery prior to the formation of a coated-film electrode. The coated-film electrode is formed by screen-printing a coating solution on the water-repellent layer. The coating solution is restricted from spreading on the surface of the water-repellent layer and a narrow ridge-shaped coated-film electrode is formed. Thus, the front electrode is smaller in width and larger in height, so received light loss and transmission loss are decreased.

Method of making a solar battery

A thin film forming apparatus using laser includes a chamber (1), a target (5) placed therein, a laser light source (10) for emitting laser beam to target (5), and a substrate holder (3). When target (5) is irradiated with laser beam (16), a plume (15) is generated, and materials included in plume (15) are deposited on the surface of a substrate (2) held by substrate holder (3). The laser beam emitted from laser light source (10) has its cross section shaped to a desired shape when passed through a shielding plate (4804), for example, so that the surface of the target (5) is irradiated with the beam having uniform light intensity distribution. Therefore, a plume (15) having uniform density distribution of active particles is generated, and therefore a thin film of high quality can be formed over a wide area with uniform film quality, without damaging the substrate.
