Abstract
Tandem photovoltaic cells, as well as related systems, methods, and components, are disclosed.
Claims34
A system, comprising:
- a first semi-cell comprising a first electrode, a third electrode, and a first photoactive layer between the first and third electrodes;
- and
- a second semi-cell comprising a second electrode, the third electrode, and a second photoactive layer between the second and third electrodes;
- wherein the first and second semi-cells are electrically connected in parallel;
- the third electrode is between the first and second electrodes and comprises a first material selected from the group consisting of metals, carbon nanotubes, carbon nanorods, fullerenes, and combinations thereof;
- and the system is configured as a photovoltaic system.
3 more elements
A system, comprising:
- first and second electrodes, the first and second electrodes having the same polarity during use of the system;
- a third electrode between the first and second electrodes, the third electrode having a polarity opposite to the polarity of the first and second electrodes during use of the system;
- a first photoactive layer between the first and third electrodes;
- and
- a second photoactive layer between the second and third electrodes;
- wherein the third electrode comprises first and second materials, the first material being selected from the group consisting of metals, carbon nanotubes, carbon nanorods, fullerenes, and combinations thereof and the second material being selected from the group consisting of metal oxides, electrically conductive polymers, and combinations thereof;
- and the system is configured as a photovoltaic system.
4 more elements
A system, comprising:
- a tandem photovoltaic cell, comprising:
- two semi-cells;
- and
