摘要:
The present invention discloses a method for extracting of solar cell parameters. After illuminating the solar cell by different simulated solar luminosity with different illumination intensity, measured current and measured voltages of the solar cell are acquired and the series resistance of the solar cell is extracted based on the measured current and measured voltages. The root mean square error (RMSE) is used to determine the series resistance of the solar cell. Therefore, the parameters of the solar cell are extracted without presuming current-voltage functional form.

The present invention provides an organic solar cell with oriented distribution of carriers, which forming variation of distribution of electron donors and electron acceptors between active sub-layers of an active layer by utilizing buffer layer method, for improving carrier extraction efficiency and thus effectively enhancing performance of the organic solar. The present invention also provides a method for manufacturing an organic solar cell with oriented distribution of carriers.
摘要:
The present invention provides a kind of structure of a thin film solar cell, including: a transparent conductive layer, a first electrode, a second electrode, a conductive layer of metal, and a photoelectric conversion layer, wherein changing the structures of said first electrode and said second electrode can improve the efficiency of the cell. Because the distribution of electric potential is not uniform in the transparent conductive layer, it will reduce the efficiency of the cell. We can solve this problem by changing the electrode structures of the cell, and improve the efficiency of the cell.

A sucker assembly having a helical spring is provided. The sucker assembly includes a sucking disk and the helical spring. In use, when an external force is applied to the sucking disk against an external surface, the helical spring is pressed simultaneously, so that the helical spring gives a counterforce to the sucking disk, thereby improving adhesion between the sucking disk and the external surface.
