19·9%‐efficient ZnO/CdS/CuInGaSe2 solar cell with 81·2% fill factor Tập 16 Số 3 - Trang 235-239 - 2008
Ingrid Repins, Miguel Á. Contreras, Brian Egaas, Clay DeHart, John Scharf, Craig L. Perkins, Bobby To, R. Noufi
AbstractWe report a new record total‐area efficiency of 19·9% for
CuInGaSe2‐based thin‐film solar cells. Improved performance is due to higher
fill factor. The device was made by three‐stage co‐evaporation with a modified
surface termination. Growth conditions, device analysis, and basic film
characterization are presented. Published in 2008 by John Wiley & Sons, Ltd.

AbstractAn updated tabulation is presented of the optical properties of
intrinsic silicon relevant to solar cell calculations. the absorption
coeficient, refractive index and extinction coeficient at 300 K are tabulated
over the 0.25‐1.45 μm wavelength range at 0.01 μm intervals.
Thin film solar cell with 8.4% power conversion efficiency using an earth‐abundant Cu2ZnSnS4 absorber 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).

Thin‐film solar cells: device measurements and analysis Tập 12 Số 2-3 - Trang 155-176 - 2004
Steven Hegedus, William N. Shafarman
AbstractCharacterization of amorphous Si, CdTe, and Cu(InGa)Se2‐based thin‐film
solar cells is described with focus on the deviations in device behavior from
standard device models. Quantum efficiency (QE), current–voltage (J–V), and
admittance measurements are reviewed with regard to aspects of interpretation
unique to the thin‐film solar cells. In each case, methods are presented for

AbstractWe report the growth and characterization of record‐efficiency
ZnO/CdS/CuInGaSe2 thin‐film solar cells. Conversion efficiencies exceeding 19%
have been achieved for the first time, and this result indicates that the 20%
goal is within reach. Details of the experimental procedures are provided, and
material and device characterization data are presented. Published in 2003 by

Comparative study of maximum power point tracking algorithms 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
Device characteristics of a 10.1% hydrazine‐processed Cu2ZnSn(Se,S)4 solar cell Tập 20 Số 1 - Trang 6-11 - 2012

ABSTRACTA power conversion efficiency record of 10.1% was achieved for kesterite
absorbers, using a Cu2ZnSn(Se,S)4 thin‐film solar cell made by hydrazine‐based
solution processing. Key device characteristics were compiled, including
light/dark J–V, quantum efficiency, temperature dependence of Voc and series
resistance, photoluminescence, and capacitance spectroscopy, providing important
