Problems solved by technology
Since the laser cutting method requires a very high working temperature, crystal particles are likely to be produced on the cut surface of the light-transmitting conductive layer 14 or the light-impermeable electrode layer 18, which increases the leakage current of the penetrating solar cell module 10 and even causes light transmission. A short circuit between the conductive layer 14 and the opaque electrode layer 18 destroys the power generation function

Description
technical field [0001] The present invention relates to a solar cell module and a method for manufacturing a penetrating solar cell module, in particular to a penetrating solar cell module with a light-transmitting effect and a method for manufacturing a penetrating solar cell module with a light-transmitting effect . Background technique [0002] Generally speaking, traditional solar cells can be divided into two types: penetrating and non-penetrating. Non-penetrating solar cells have been widely used in various building materials, such as roof tile structures, wall patches, roof panels, etc. And in some special applications, such as glass curtains, transparent roofs, etc., it is necessary to match the penetrating solar cells with light transmission to have optimal aesthetics. see figure 1 , figure 1 It is a schematic diagram of a permeable solar cell module 10 in the known technology. A conventional transmissive solar cell module 10 includes a transparent substrate 12...
