が起こり最大出力の劣化が約３０％あった。Problems to be Solved by the Invention However, conventional screen-printable epoxy resins have low viscosity and thixotropy, and during the drying process after screen printing, they soak into the underlying carbon electrode layer, causing unevenness of the underlying carbon electrode layer. appears, resulting in poor appearance, and in extreme cases, the carbon electrode may become exposed as the film thickness becomes thinner. For this reason, moisture etc. easily entered the cell, and exposure to light caused an electrochemical reaction between CdS and CdTe, resulting in a deterioration of the maximum output by about 30%.

ある。The present invention has been made in view of this point, and is intended to prevent performance deterioration by increasing the molecular weight of the main ingredient of an epoxy resin to increase viscosity, chicken tropism, surface tension, etc.

脂が薄い部分もあり、したがって信頼性も悪かった。The only way to solve the problem is that the chicken tropism is low, and the unevenness of the carbon electrode layer deteriorates the appearance, and the unevenness also makes the resin thin in some parts, so the reliability is low It was also bad.

The thickness is increased from 0.about.30 .mu.m to 60.about.60 .mu.m, and the unevenness of the carbon electrode layer is not visible in appearance, thereby improving the appearance and reliability.

のにすることができる効果が得られた。Examples Examples of the present invention will be explained below with reference to Fig. 1. Fig. 1 shows a slurry made by adding CdCl2 as a flux to CdS powder and propylene glycol as a binder. As shown in Figure 2, a barium borosilicate glass substrate 1 is screen printed, dried, placed in a ceramic container with a perforated lid, and sintered in a belt-type sintering furnace. On the n-type CdS sintered film 2 sintered in this way, Cd powder and Te powder are mixed in an equimolar ratio, and Cd powder is added as a flux.
12 by 0.5% by weight based on the total weight of Cd and To, and an appropriate amount of propylene glycol as a binder are added and mixed,
The slurry is screen printed and dried and fired in the same way as CdS. In this manner, a CdTe sintered film 3 was formed. Next, muddy carbon containing an appropriate amount of acceptor impurities is screen printed on the CdTe sintered film, dried and sintered to form the carbon film 4. Next, Ag I n films 5 and 6 as ohmic electrodes were screen printed on the CdS sintered film 2 and the carbon film 4, respectively, and were dried and sintered. The reliability of the device obtained in this way,
In order to improve water resistance, epoxy resin 7 with a main resin molecular weight of 2500 was screen printed and
The present invention improves the appearance and improves the appearance by increasing the molecular weight of the main ingredient of the epoxy resin used as a coating material for CdS/CdTe solar cells. The effect of achieving reliability and no deterioration of characteristics was obtained.
