A generic concept to overcome bandgap limitations for designing highly efficient multi-junction photovoltaic cells
The multi-junction concept is the most relevant approach to overcome the Shockley-Queisser limit for single-junction photovoltaic cells. The record efficiencies of several types of solar technologies are held by series-connected tandem configurations. However, the stringent current-matching criterion presents primarily a material challenge and permanently requires developing and processing nove...
متن کاملTriple-Junction Hybrid Tandem Solar Cells with Amorphous Silicon and Polymer-Fullerene Blends
Organic-inorganic hybrid tandem solar cells attract a considerable amount of attention due to their potential for realizing high efficiency photovoltaic devices at a low cost. Here, highly efficient triple-junction (TJ) hybrid tandem solar cells consisting of a double-junction (DJ) amorphous silicon (a-Si) cell and an organic photovoltaic (OPV) rear cell were developed. In order to design the T...
متن کاملGuidelines for the Bandgap Combinations and Absorption Windows for Organic Tandem and Triple-Junction Solar Cells
Organic solar cells have narrow absorption windows, compared to the absorption band of inorganic semiconductors. A possible way to capture a wider band of the solar spectrum—and thus increasing the power conversion efficiency—is using more solar cells with different bandgaps in a row, i.e., a multi-junction solar cell. We calculate the ideal material characteristics (bandgap combinations and ab...
متن کاملInvestigation of Indigo/thioindigo Tandem Dye-Sensitized Solar Cells
In this paper we used two free-metal organic dyes (dye 1 and dye 2) based on indigo and thioindigo with cyanoacrylic acid as the electron acceptor group. The proposed dyes were sensitized from naphalene as the starting material by standard reactions and characterized by different analytical techniques and UV-Visible spectroscopy after purification. Spectrophotometric measurements of the organic...
متن کاملAn efficient triple-junction polymer solar cell having a power conversion efficiency exceeding 11%.
Tandem solar cells have the potential to improve photon conversion efficiencies (PCEs) beyond the limits of single-junction devices. In this study, a triple-junction tandem design is demonstrated by employing three distinct organic donor materials having bandgap energies ranging from 1.4 to 1.9 eV. Through optical modeling, balanced photon absorption rates are achieved and, thereby, the photo-c...
