Journal ArticleDOI
Polycrystalline CdSeTe/CdTe Absorber Cells With 28 mA/cm 2 Short-Circuit Current
Amit Munshi,Jason M. Kephart,Ali Abbas,John Raguse,Jean-Nicolas Beaudry,Kurt L. Barth,James R. Sites,John M. Walls,Walajabad S. Sampath +8 more
TL;DR: In this paper, an 800 nm CdSeTe layer was added to the CdTe absorber used in high-efficiency cdTe cells to increase the current and produce an increase in efficiency.
Journal ArticleDOI
Understanding the role of selenium in defect passivation for highly efficient selenium-alloyed cadmium telluride solar cells
Thomas A. M. Fiducia,Budhika G. Mendis,Kexue Li,Chris R. M. Grovenor,Amit Munshi,Kurt L. Barth,Walajabad S. Sampath,Lewis D. Wright,Ali Abbas,Jake W. Bowers,John M. Walls +10 more
TL;DR: Fiducia et al. as mentioned in this paper showed that selenium enables higher luminescence efficiency and longer diffusion lengths in the alloyed material, indicating that Selenium passivates critical defects in the bulk of the absorber layer.
Journal ArticleDOI
Polycrystalline CdTe photovoltaics with efficiency over 18% through improved absorber passivation and current collection
Amit Munshi,Jason M. Kephart,Ali Abbas,Tushar M. Shimpi,Kurt L. Barth,John M. Walls,Walajabad S. Sampath +6 more
TL;DR: In this article, a sputtered multilayer metal-oxide anti-reflection layer was proposed for CdTe photovoltaic devices with conversion efficiencies over 18% and a fill factor greater than 79%.
Journal ArticleDOI
Fabrication of CdS/CdTe-Based Thin Film Solar Cells Using an Electrochemical Technique
I. M. Dharmadasa,Paul A. Bingham,Obi Kingsley Echendu,H. I. Salim,Thad Druffel,Ruvini Dharmadasa,Gamini Sumanasekera,Ruchira Dharmasena,M. B. Dergacheva,K.A. Mit,K. A. Urazov,L Bowen,Michael Walls,Ali Abbas +13 more
TL;DR: In this paper, a wide range of analytical techniques was used to investigate the materials and device structures of thin film solar cells based on cadmium telluride (CdTe) and found that n-, i-and p-type CdTe can be grown easily by electroplating.
Journal ArticleDOI
The structural properties of CdS deposited by chemical bath deposition and pulsed direct current magnetron sputtering
Fabiana Lisco,P.M. Kaminski,Ali Abbas,K. Bass,Jake W. Bowers,Gianfranco Claudio,Maria Losurdo,John M. Walls +7 more
TL;DR: In this paper, Cadmium sulphide (CdS) thin films were deposited by two different processes, chemical bath deposition (CBD), and pulsed DC magnetron sputtering (PDCMS) on fluorine doped-tin oxide coated glass to assess the potential advantages of the pulsed dc magnetron (DC magnetron) sputtering process.
