Emitter sheet resistance significantly contributes to the distributed series resistance of the solar cell. The series resistance (Rs) has an impact on the fill factor (FF) and in turn has an effect on the short circuit current (Isc) and as a result the efficiency.
We investigate the concept of nanoparticle-based solar cells composed of a silicon nanoparticle stack as a light trapping absorber for ultrathin photovoltaics. We study the potential of using ...
The imperfect charge behavior at the interfaces of perovskite/electron-transport layer (ETL)/transparent conducting oxide (TCO) limits the further performance improvement of perovskite/silicon tandem solar cells. Herein, an indium tin oxide interlayer is deposited between ETL and TCO to address this …

Series resistance (R s) is considered to be one of the most important parameters affecting solar cell performance, especially those operating under concentrated solar radiation. Many methods have been proposed where the estimated R s values do not coincide or even come close to each other. In this paper, seven methods for determining …

The intrinsic loss processes of a crystalline silicon (c-Si) solar cell at different concentration ratios (n = 1 and 5) with the bandgap of 1.1246 eV at 298.15 K (25 °C) are presented in Table 1, under an AM1.5 solar illumination (P Incident = 1000.37 W/m 2, calculated by the integral of PFD(E)).The errors Δ in the table equal to the differences …
Photoluminescence Imaging for Photovoltaic Applications
In this paper we include the electric characterization of contacts, and solar silicon heterojunction (SHJ) cells metalized with both techniques. The results show a slightly better efficiency for the screen-printed cells, but good series resistance and fill factor values imply that LIFT is a promising alternative for device metallization.
Screen-printing technology has long been used for the metallization of solar cells since the 1970s. 11 Benefiting from its simple and robust process, low equipment and process costs and high throughput, the screen-printing technology has established itself as the dominant metallization technology for industrial silicon solar cells with more ...
