Abstract

Consolidated tables showing an extensive listing of the highest independently confirmed efficiencies for solar cells and modules are presented. Guidelines for inclusion of results into these tables are outlined and new entries since January 2008 are reviewed.

Table I. Confirmed terrestrial cell and submodule efficiencies measured under the global AM1-5 spectrum (1000 W/m?) at 25°C (U1Gs, CulnGasez, a-sl1, amorphous silicon/nydrogen alloy. \Effic., efficiency. ‘ap), aperture area; (t), total area; (da), designated illumination area. SER, fill factor. \|IFhG-ISE, Fraunhofer Institut fiir Solare Energiesysteme; JQA, Japan Quality Assurance; AIST, Japanese National Institute of Advancec Industrial Science and Technology. ‘Reported on a ‘per cell’ basis. *Not measured at an external laboratory. “Stabilised by 800h, I sun AMI-5 illumination at a cell temperature of 50°C. Ti Stability not investigated. “Stabilised by 174h, 1 sun illumination after 20h, 5 sun illumination at a sample temperature of 50°C.

Table II. Confirmed terrestrial module efficiencies measured under the global AM1-5 spectrum (1000 W/m”) at a cell temperature of 25°C *CIGSS, CuInGaSSe; a-Si, amorphous silicon/hydrogen alloy; a-SiGe, amorphous silicon/germanium/hydrogen alloy. \Effic., efficiency. ‘(ap), aperture area; (da), designated illumination area. SRR, fill factor. Not measured at an external laboratory. “Light soaked at NREL for 1000h at 50°C, nominally 1 sun illumination.

Table III. ‘Notable exceptions’: ‘top 10’ confirmed cell and module results, not class records (global AM1-5 spectrum, 1000 W/m?, 25°C) *CIGS, CulnGaSe>. \Effic., efficiency. ‘ap), aperture area; (t), total area; (da), designated illumination area. 8Stability not investigated. INot measured at an external laboratory.

Table IV. Terrestrial concentrator cell and module efficiencies measured under the direct-beam AM1-5 spectrum at a cell temperature of 25°C “Effic., efficiency. i(da), designated illumination area; (ap), aperture area. One sun corresponds to direct irradiance of 1000 W/m”. ’Measurements corrected from originally measured values due to Sandia recalibration in January 199 Not measured at an external laboratory.
