A high efficiency solution processed polymer inverted triple-junction solar cell exhibiting a power conversion efficiency of 11.83%

Abstract

We propose that 1 + 1 + 1 triple-junction solar cells can provide an increased efficiency, as well as a higher open circuit voltage, compared to tandem solar cells.

Surface passivation effect by fluorine plasma treatment on ZnO for efficiency and lifetime improvement of inverted polymer solar cells

“…Several approaches have been proposed and studied extensively to harvest solar energy; among them polymer solar cells (PSCs) based on bulk-heterojunctions (BHJs) consisting of polymer donors and fullerene acceptors have attracted extensive investigation as a potential alternative to conventional cells, mainly due to their inherent advantages of being low-cost and compatible with large area flexible substrates and solution-based processing techniques. [1][2][3][4][5][6] The state of the art power conversion efficiencies (PCEs) of single junction PSCs exceeding 9%, [7][8][9] while efficiencies higher than 11% have been achieved in small area tandem cells, [10][11][12][13] which promises a bright future for the commercialization of such devices. To achieve higher power conversion efficiencies in PSCs, appropriate interfacial engineering based on suitable materials and processes has been identified as an essential approach for forming anode and cathode contacts of high quality, so as to optimize the hole and electron transport and collection.…”

Synthesis and property characterization of two novel side-chain isoindigo copolymers for polymer solar cells

“…Recently, great advances have been made in the development of high-efficiency photovoltaic materials and device structures, especially in multiple-junction tandem solar cell and ternary solar cells. In 2015, an efficient triple-junction tandem solar cell designed by Yusoff et al got record-high power conversion efficiency (PCE) of 11.83% in PSCs [9]. On the other hand, ternary solar cells have attracted more and more attention due to the advantages to extend the absorption spectra of large-band-gap polymers to the near IR region and to enhance light harvesting in single-junction BHJ solar cells [10][11][12][13][14].…”

A Review on the Thieno [2,3-c]pyrrole-4,6-dione-based small molecules for Organic Photovoltaic Cells

“…In the meantime, solution processed organic photovoltaic cell (OPV) have received tremendous amount of consideration due to its advantages compares to inorganic silicon based such as low cost, lightweight, and flexible [3][4][5] . For the past few years, significance progress had been made with OPV based on conjugated polymer with power conversion efficiency of 9% [6] for single layer BHJ and 11% [7,8] for tandem junction OPV cells. The good progress was mainly because of extensive development of perfect electron donating polymers and device optimization [9] .…”
