Comparative study of maximum power point tracking algorithmsProgress in Photovoltaics: Research and Applications - Tập 11 Số 1 - Trang 47-62 - 2003
D. P. Hohm, Michael Ropp
AbstractMaximum power point trackers (MPPTs) play an important role in
photovoltaic (PV) power systems because they maximize the power output from a PV
system for a given set of conditions, and therefore maximize the array
efficiency. Thus, an MPPT can minimize the overall system cost. MPPTs find and
maintain operation at the maximum power point, using an MPPT algorithm. Many
such algorithms have ... hiện toàn bộ
Ideal efficiency of monolithic, series‐connected multijunction solar cellsProgress in Photovoltaics: Research and Applications - Tập 10 Số 5 - Trang 323-329 - 2002
Irwin Tobias, A. Ĺuque
AbstractTwo‐terminal, monolithic tandem solar cells represent the most
interesting implementation of tThe multijunction photovoltaic array capable of
very high efficiency. Radiative coupling among the cells, and between the cells
and the substrate, along with series interconnection are features present in
this approach. Their effect on efficiency is quantified for arrays with a small
number of cel... hiện toàn bộ
Thin film solar cell with 8.4% power conversion efficiency using an earth‐abundant Cu2ZnSnS4 absorberProgress in Photovoltaics: Research and Applications - Tập 21 Số 1 - Trang 72-76 - 2013
Byungha Shin, Oki Gunawan, Yu Zhu, N. A. Bojarczuk, S. Jay Chey, Supratik Guha
ABSTRACTUsing vacuum process, we fabricated Cu2ZnSnS4 solar cells with 8.4%
efficiency, a number independently certified by an external, accredited
laboratory. This is the highest efficiency reported for pure sulfide Cu2ZnSnS4
prepared by any method. Consistent with literature, the optimal composition is
Cu‐poor and Zn‐rich despite the precipitation of secondary phases (e.g., ZnS).
Despite a very ... hiện toàn bộ
Tuning solar absorption spectra via carbon quantum dots/VAE composite layer and efficiency enhancement for crystalline Si solar moduleProgress in Photovoltaics: Research and Applications - Tập 27 Số 4 - Trang 283-289 - 2019

AbstractIn this work, fluorescent carbon quantum dots (CQDs) composite
transparent film with blue emission was prepared via hydrothermal fabrication,
mixing with vinyl acetate‐ethylene (VAE) emulsion, coated and cross‐linked on
the glass in sequence. This CQD/VAE film has good sticking ability and
compatibility of sealing ethylene‐vinyl acetate (EVA) material and works well as
luminescent downshif... hiện toàn bộ
Rapid annealing of reactively sputtered precursors for Cu2ZnSnS4 solar cellsProgress in Photovoltaics: Research and Applications - Tập 22 Số 1 - Trang 10-17 - 2014

ABSTRACTCu2ZnSnS4 (CZTS) is a promising thin‐film absorber material that
presents some interesting challenges in fabrication when compared with
Cu(In,Ga)Se2. We introduce a two‐step process for fabrication of CZTS films,
involving reactive sputtering of a Cu‐Zn‐Sn‐S precursor followed by rapid
annealing. X‐ray diffraction and Raman measurements of the sputtered precursor
suggest that it is in a di... hiện toàn bộ

Improved performance in ZnO/CdS/CuGaSe2 thin‐film solar cellsProgress in Photovoltaics: Research and Applications - Tập 11 Số 8 - Trang 535-541 - 2003

AbstractWe report the growth and characterization of improved efficiency
wide‐bandgap ZnO/CdS/CuGaSe2 thin‐film solar cells. The CuGaSe2 absorber
thickness was intentionally decreased to better match depletion widths indicated
by drive‐level capacitance profiling data. A total‐area efficiency of 9·5% was
achieved with a fill factor of 70·8% and a Voc of 910 mV. Published in 2003 by
