STABILIZATION OF MINORITY CARRIER LIFETIME IN PERC STRUCTURED SILICON SOLAR CELL
نویسندگان
چکیده
This paper reports on the regeneration of minority carrier lifetime in passivated emitter and rear cell (PERC) structured silicon solar cells. It is observed that cells can degrade, recover then stabilize with illumination level ~1 sun (1000 W/m2) at 80oC. The exposure to 80oC enables release H from B-H bonds ~1.3 eV energy supplement interstitial Si passivate B-O defects responsible for instability. Passivation these therefore, dependent temperature time, hydrogenation high injection level. was interesting note sequential process or single step led same conclusion a p-type PERC first degrades, due complexes, recovers time. There no need degrade separate order occur, because encompasses three states: degradation, recovery stabilization.

Minority carrier lifetime in plasma-textured silicon wafers for solar cells
In this work a comparison between plasma-induced defects by two different SF6 texturing techniques, reactive ion etching (RIE) and high-density plasma (HDP) is presented. It is found that without any defect-removal etching (DRE), the minority carrier lifetime is the highest for the HDP technique. After DRE, the minority carrier lifetime rises as high as 750 ms for both RIEand HDP-textured wafer...
متن کاملEffect of Silicon Nanowire on Crystalline Silicon Solar Cell Characteristics
Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...
متن کاملImpact of grown-in point-defects on the minority carrier lifetime in Czochralski-grown silicon wafers
In this study, we investigate the nature of some recombination active defects limiting the lifetime in Czochralski (CZ) silicon wafers, in the millisecond range. Due to their low concentrations, the observed defects are unlikely to be identified through Deep-Level Transient Spectroscopy (DLTS) or Electron Paramagnetic Resonance (EPR), hence we use lifetime spectroscopy combine with several anne...
