Embodiment 1

[0046] Such as Figure 3 ~ Figure 7 As shown, the design of the solar power compensation device combined with the mobile phone protective case is as follows: use a loose-leaf mobile phone case, and fix two double-junction silicon thin-film solar cell modules on the outer surface of the loose-leaf respectively. The voltage of the device reaches above 5.5V. The dimensions of the two battery modules used are 57×93mm and 57×100mm respectively. The two modules are connected in parallel to the output plug. When the photoelectric conversion efficiency of the solar cells used is 12%, the output current can reach 260mA. The output plug is fixed in the middle of the loose-leaf of the mobile phone cover, which can be directly inserted into the charging socket of the mobile phone, and can keep the mobile phone cover from affecting the normal use of the mobile phone when inserted. The charging management software in the mobile phone can monitor the status of the mobile phone plug in real ...

Abstract

The invention relates to a power source compensation device and method based on a solar cell. A charging device is connected with a control circuit or a power source control system integrated in an electric appliance and is the solar cell. The method includes the following steps: the charging device is connected to an electric appliance power connector, the electric appliance carries out voltage-current scanning on the output of the charging device through a microprocessor, when the absolute value of the difference between a detected open-circuit voltage value and a set voltage value is smaller than a threshold value, the microprocessor gives a control signal to a switch power source controller to enable the switch power source controller to control a switch power source to enable the output voltage of the charging device to be output to the switch power source at the set voltage, and the switch power source charges an electric appliance electricity-storage device at a fixed voltage value. By means of the power source compensation device, the hull cell is used as the power source; in addition, the stable voltage can be output to charge the electric appliance, and the power source compensation device and method can be widely used for different electric appliances.

Description

technical field [0001] The invention relates to a device and method for converting solar energy into electric energy to compensate electrical power supply. In particular, the device and method use solar cells to generate electric energy, and use integrated circuits or software to manage the power of electrical appliances, so as to increase the battery life of electrical appliances. Background technique [0002] A solar cell is a device that converts solar energy into electrical energy. When photons enter the solar cell, electron-hole pairs are generated. After the electrons and holes are separated, they are exported to the positive and negative electrodes of the solar cell to generate voltage. [0003] Using solar cells to supplement power for portable devices is one of the many application fields of solar cells, which can make mobile terminals free from dependence on external power grids during a longer service life. [0004] At present, the solar charging device needs to ...
