High performance polymer tandem solar cell
A power conversion efficiency of 9.02% is obtained for a fully solution-processed polymer tandem solar cell, based on the diketopyrrolopyrrole unit polymer as a low bandgap photoactive material in the rear subcell, in conjunction with a new robust interconnecting layer. This interconnecting layer is optically transparent, electrically conductive, and physically strong, thus, the charges can be ...
متن کاملPlasmonic polymer tandem solar cell.
We demonstrated plasmonic effects in an inverted tandem polymer solar cell configuration by blending Au nanoparticles (NPs) into the interconnecting layer (ICL) that connects two subcells. Experimental results showed this plasmonic enhanced ICL improves both the top and bottom subcells' efficiency simultaneously by enhancing optical absorption. The presence of Au NPs did not cause electrical ch...
متن کاملHigh efficiency all-polymer tandem solar cells
In this work, we have reported for the first time an efficient all-polymer tandem cell using identical sub-cells based on P2F-DO:N2200. A high power conversion efficiency (PCE) of 6.70% was achieved, which is among the highest efficiencies for all polymer solar cells and 43% larger than the PCE of single junction cell. The largely improved device performance can be mainly attributed to the enha...
متن کاملHigh-efficiency polymer tandem solar cells with three-terminal structure.
Figure 1. a) Two diodes connected in parallel with the anodes of the two diodes connected together and the cathodes connected together. b) Schematic of the three-terminal device and the dotted squares on Polymer solar cells are a promising alternative to future photovoltaic applications due to various advantages such as low cost and ease of processing. Ever since the invention of bulk heterojun...
متن کاملA polymer tandem solar cell with 10.6% power conversion efficiency
An effective way to improve polymer solar cell efficiency is to use a tandem structure, as a broader part of the spectrum of solar radiation is used and the thermalization loss of photon energy is minimized. In the past, the lack of high-performance low-bandgap polymers was the major limiting factor for achieving high-performance tandem solar cell. Here we report the development of a high-perfo...
