Embodiment 1
[0066] Such as Figure 1~3 As shown, this embodiment relates to a parallel perovskite solar cell module. The specific implementation steps include:
[0067] The perovskite solar cell modules arranged in 2 rows and 4 columns are laid on the tempered glass (bottom substrate 1). A transparent substrate 3a with a transparent conductive layer 3b formed on the lower surface is provided on the perovskite solar cell module. A single perovskite solar cell module includes from top to bottom: a hole blocking layer 3c, an electron transport layer 3d, a perovskite light absorbing layer 3e, a hole transport layer 3f, and a counter electrode layer 3g; wherein, the transparent conductive layer 3b is provided with There is a total electrode 5, which is used as the positive and negative terminals of a single perovskite battery module. A filling layer 2 is laid between a single perovskite solar cell module and the bottom substrate 1 , and encapsulation glue 4 is laid around the single perovsk...
Embodiment 2
[0071] Such as Figure 5~8 As shown, this embodiment relates to a tandem perovskite solar cell module. The specific implementation steps include:
[0072] When the first row of perovskite solar cell modules are placed, the direction of positive and negative poles is the left side is the negative pole, and the right side is the positive pole; when the second row of perovskite solar cell modules is placed, the direction of the positive and negative poles is the left side is the positive pole , the right side is negative.
[0073] Use conductive copper tape (connecting wire 6) to connect the positive and negative electrodes of the perovskite solar power module laid above, and follow the Figure 7 The perovskite solar cell arrays are connected in series in the same way; after the series connection, the positive and negative electrodes are collected at one end of the tempered glass respectively, and the positive and negative electrodes are respectively passed through the through ...
