Effective surface passivation of Si surfaces by chemical deposition of (Al2O3)x(B2O3)1 − x thin layers
Petko Vitanov,Antoaneta Harizanova,Tatyana Ivanova,Michele Perego,Gaute Stokkan,Alexander Ulyashin,Alexander Ulyashin +6 more
TL;DR: In this article, chemical liquid deposition from sol-gel solutions has been used to obtain thin (Al2O3)x(B2O 3)1 − x dielectric films, which can be used as back side passivation for Si-based solar cells.
Journal ArticleDOI
Performance and stability of two types of bulk heterojunction polymer solar cells with sputtered back contacts
M. Sendova-Vassileva,G Popkirov,Petko Vitanov,G. Grancharov,Valeria Gancheva,Hristosko Dikov,E Lazarova,R Gergova +7 more
TL;DR: In this paper, two types of polymer solar cells with active layers of P3HT:PCBM and PCDTBT:PCB were deposited by spincoating the polymer layers and sputtering the Ag back contacts.
Book ChapterDOI
Dilute Nitride GaAsN and InGaAsN Layers Grown by Low-Temperature Liquid-Phase Epitaxy
M. Milanova,Petko Vitanov +1 more
TL;DR: In this article, the authors proposed to use dilute nitride alloys such as GaInAsN, GaAsSbN, and GaAsNbN to improve the performance of multijunction solar cells.
Journal ArticleDOI
Solar cell technology on the base of III–V heterostructures
TL;DR: In this paper, a single-junction GaAs solar cells on the base of p-AlGaAs,p-GaAs/p-GAAs/n-GaA heterostructures grown by low-temperature liquid-phase epitaxy have been fabricated for analyzing the factors contributing to solar cell efficiency.
