Dependence of open-circuit voltage in hydrogenated protocrystalline silicon solar cells on carrier recombination in pÕi interface and bulk regions
نویسندگان
چکیده
Contribution of carrier recombination from the p/i interface regions and the bulk to the dark current–voltage (JD – V) and short-circuit current–open-circuit voltage (Jsc– Voc) characteristics of hydrogenated amorphous-silicon ~a-Si:H! p–i–n and n–i–p solar cells have been separated, identified, and quantified. Results are presented and discussed here which show that a maximum 1 sun Voc for a given bulk material can be validly extrapolated from bulk dominated Jsc– Voc characteristics at low illumination intensities. © 2000 American Institute of Physics. @S0003-6951~00!01445-5#

Quantitative Correlation of High Quality a-Si:H p-i-n Solar Cell Characteristics with Properties of the Bulk and p/i Interface Region
Studies have been carried out on high quality hydrogenated amorphous silicon (a-Si:H) p-i-n solar cells with protocrystalline i-layers to establish the nature of p/i interfaces and to quantify their contributions to various solar cell characteristics. The p-a-SiC:H:B/i-a-Si:H/n-μcSi:H:P cell structures used had the a-Si:H i-layers deposited from hydrogen diluted silane with R≡[H2]/[SiH4]=10. Th...
متن کاملMaximization of the open circuit voltage for hydrogenated amorphous silicon n – i – p solar cells by incorporation of protocrystalline silicon p-type layers
In studies of hydrogenated amorphous silicon (a-Si:H) n – i – p solar cells fabricated by rf plasma-enhanced chemical vapor deposition ~PECVD!, we have found that the maximum open circuit voltage (Voc) is obtained by incorporating p-type doped Si:H layers that are protocrystalline in nature. Specifically, these optimum p layers are prepared by PECVD in the a-Si:H growth regime using the maximum...

Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...
