摘要： A method for improving contact resistance of a multi-junction solar cell having a front and a back and multiple subcells, including: a) delivering the solar cell with front and back contacts in grid, strip or transparent form; b) contact-connecting one region of the back contact to a contact device connected to one pole of a voltage source, and the front contact or another region of the back contact, which is electrically insulated from the region, to another contact device, which is connected to the other pole of the voltage source; c) applying a voltage against the forward direction of the solar cell to the contacts, the voltage smaller than a solar cell breakdown voltage; d) guiding a point light source over the solar cell, a subregion of the front or back being illuminated, inducing current in the subregion, and illuminating the subregion with light beams of different wavelengths.

摘要： In multijunction photovoltaic cells, such as for example tandem solar cells having a top sub-cell and a crystalline silicon based bottom sub-cell, efficiency of conversion of solar energy into electrical energy is limited mainly by the junction between a top sub-cell and a bottom sub-cell of the multijunction photovoltaic cell. A multijunction photovoltaic cell of this disclosure at least partially overcomes this drawback because it has an intermediate layer of silicon nitride deposited in a conformal manner with a thickness of between 1 and 10 nm so as to define a P-N tunnel junction between the top sub-cell and the bottom sub-cell. A related fabrication process is also disclosed.

摘要： A solar cell includes a first photoelectric conversion part, a second photoelectric conversion part, a first electrode, and a second electrode. The first photoelectric conversion part includes a photoelectric conversion layer containing a perovskite compound, a first transport layer, and a second transport layer. The second photoelectric conversion part is arranged below the second transport layer of the first photoelectric conversion part and has a different material or structure from the first photoelectric conversion part. The first electrode is electrically connected to the first photoelectric conversion part on one surface of the first photoelectric conversion part, and the second electrode is electrically connected to the second photoelectric conversion part below the second photoelectric conversion part. The first electrode has a stacking structure of at least two layers, and the second electrode is formed as a single layer.

摘要： A multi-junction photovoltaic device comprising a layer of metal oxynitride between a first sub-cell and a second sub-cell is disclosed, the first sub-cell having a layer comprising a perovskite light absorber material. In addition, a method of manufacturing said multi junction photovoltaic device is disclosed. The metal oxynitride is preferably titanium oxynitride. Advantageously, the device may be produced in a simple, fast, consistent and inexpensive manner, whilst the properties of the titanium oxynitride layer may be tuned to avoid the occurrence of local shunt paths and to reduce reflection losses.
