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...

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 da...... hiện toàn bộ 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 algo...... 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
