Problems solved by technology

The battery structure includes a substrate, a cathode electrode, an electron transport layer, an active layer, an exciton supply layer, a hole transport layer, and an anode electrode arranged in sequence from bottom to top, and the active layer is composed of a mixture of a donor material and an acceptor material. The exciton supply layer includes delayed fluorescent materials, but due to the instability and low efficiency of the organic fluorescent materials used, there is still a long way to go before commercialization

Abstract

The invention belongs to the technical field of solar cells, and particularly relates to a double-layer processed all-polymer organic solar cell and a preparation process thereof. The preparation of the all-polymer solar cell is as follows: a normal structure sequentially comprises a transparent electrode layer, a hole transport layer 2PACz, an active layer donor PM6, an active layer receptor PYF-T-o, an electron transport layer PDINN and cathode metal from bottom to top; the inverted structure sequentially comprises a transparent electrode layer, an electron transport layer ZnO, an active layer receptor PYF-T-o, an active layer donor PM6, a hole transport layer MnO3 and anode metal from bottom to top; through double-layer combination of the polymer PYF-T-o and PM6, the PYF-T-o exerts more ordered inter-chain filling and proper phase separation, so that charge recombination is inhibited, and effective charge transfer is obtained.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a double-layer processed all-polymer organic solar cell and a preparation process thereof. Background technique [0002] Today, with the increasing global energy demand and the depletion of primary fossil energy such as oil and coal, society is facing the dual challenges of energy shortage and environmental pollution. The rapid development of the times urgently requires the development of renewable and clean energy. Solar energy is clean, renewable and plentiful, so research efforts on new types of solar cells are attracting increasing attention. Organic solar cells have the advantages of good flexibility, low weight, low cost, and simple preparation process, so organic solar cells have high commercial prospects. [0003] As a sustainable solar energy harvesting technology, polymer solar cells have received extensive attention due to their mechanical flexibility ...
