Definitions
- the invention relates to the production of organic solar cells, which are constructed in particular on a polymer basis.
- the typical cell structure of a solar cell consists of a layer structure that contains a positive electrode, an organic semiconductor mixture and a negative electrode.
- ITO / PEDOT: PSS can be used as the material for the positive electrode.
- the semiconductor mixture consists of an organic material, for example a polymer.
- the semiconductor mixture contains both n-type semiconductor molecules and p-type semi-conductor molecules.
- This semiconductor mixed layer is referred to as a bulk heterojunction layer.
- Materials that are also used relate, for example, to the negative electrode, which can consist of Ca / Ag or LiF / Al. However, the substances listed above do not exclusively represent the corresponding elements, but other material combinations are also possible.
- the donor present in the bulk mixed layer can be, for example, a conjugated polymer and the acceptor can be, for example, a soluble methanofullerene.
- a major difficulty in the production of bulk heterojunction solar cells is the formation of a desired phase morphology with respect to the n-type semiconductor and the p-type semiconductor. This problem comes among other things due to the different solubility of the individual components in the common solvent.
- the object of the invention is to specify a production method for an organic solar cell, by means of which a bulk heterojunction mixed layer can be formed.
- the invention is based on the finding that a bulk heterojunction mixed layer is possible by the serial application of solutions with only one organic semiconductor in each case.
- the focus is on the phase morphology of the n and p semiconductors.
- the phase formation must be precisely controlled during the deposition or solidification times.
- An essential contribution of the invention consists in the technologically simpler production of a bulk heterojunction cell. Although two layers to be applied in series are provided, overall there is greater freedom in the choice of solvent, combined with significant advantages for the entire production. If the layer of the heterojunction is represented as a bulk, there is an overall mixture of the n-semiconductors and the p-semiconductors.
- the figure shows the comparison of characteristic curves of solar cells which are manufactured on the one hand according to the prior art and on the other hand according to the invention.
- characteristic curves shown in the figure relate, on the one hand, shown with filled circles, to a solar cell produced with normal spin coating, both n-semiconductors and p-semiconductors being solved in one solution.
- Characteristic curves depicted with solid squares relate to a solar cell that is produced by successively applying layers, wherein during the production of each layer in the solution used either only n-
- Semiconductors are present or corresponding p-semiconductors.
- the characteristic curve according to the prior art and according to the invention do not differ significantly, both when recording a dark characteristic and when recording a characteristic under lighting.
- the main advantages of the invention are the great freedom in solvent formulation.
- An organic solar cell with a bulk heterojunction mixed layer can be represented as follows, for example:
- An organic semiconductor is first applied to a carrier substrate, for example glass, ITO / PEDOT: PSS. This is done, for example, by spin coating, knife coating or printing.
- the choice of the first solvent can be matched particularly advantageously to the solubility of the first semiconductor.
- P3HT, PPV is used as the first semiconductor.
- the formulation of the second solution is also optimized with regard to the solubility of the second semiconductor.
- a fullerene is used as the second semiconductor.
- the first semiconductor or the first semiconductor layer must have a slight solubility in the solvent for processing the second semiconductor layer.
- the second solution is applied to the first layer, which is also achieved with an additive application method such as knife coating or printing, the first semiconductor is slightly dissolved and mixes with the second semiconductor. After the solvent evaporated, a bulk heterojunction mixed layer was formed when the very thin layers were mixed. In this way, an optimal phase morphology can be achieved for every semiconductor, but at the same time extensive mixing can be achieved.
