Abstract

The invention relates to a solar cell device which comprises a conductive substrate, a doping active layer, an electron injection layer formed on the doping active layer and a cathode formed on the electron injection layer. The doping active layer is formed between the conductive substrate and the electron injection layer, and is formed by at least one selected from the group consisting of P3HT / PCBM, P3AT / PCBM, MDMO-PPV / PCBM, and MEH-PPV / PCBM doped with phthalocyanines dye micromolecule, and the cathode is formed on the electron injection layer. The solar device has relatively high photocurrent density and light absorption efficiency. In addition, a manufacturing method of the solar cell device is also provided.

Description

【Technical field】 [0001] The invention relates to a solar battery device and a preparation method thereof. 【Background technique】 [0002] Solar cells have been widely used due to their cheapness, cleanness, and renewability. Existing solar cell devices use P3HT / PCBM, P3AT / PCBM, MDMO-PPV / PCBM or MEH-PPV / PCBM as the active layer to form excitons. The active layer includes donors and acceptors, and the excitons have a built-in electric field Under the action, it diffuses to the donor / acceptor interface and separates into freely moving electrons and holes, then the electrons are transferred in the acceptor phase and collected by the cathode, and the holes pass through the donor phase and are collected by the anode, thereby generating photocurrent . However, the contact barrier between the acceptor material and the donor material in the active layer is high, resulting in low photocurrent density and energy conversion efficiency. 【Content of invention】 [0003] Based on this...
