Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a flexible photovoltaic cell product and a preparation method. Background technique [0002] At present, flexible solar cell products usually use printed electrodes or comb-shaped metal bus bars to connect solar cells in series, and the front plate of the package is usually made of waterproof and light-transmitting organic materials. Solar cell products will inevitably reduce the photoelectric conversion output due to the increase in the shading area of ​​the cell, and cannot be applied in a specific concealed demand environment. The series and parallel connections of the product are limited, and most of them are manually combined and connected. The steps of connecting and assembling components are complicated, and other methods are required to be bundled and stored after winding. [0003] How to conveniently and quickly realize the connection and combination of multi...
