Abstract
Towards improved reliability and relevance of indoor measurements of efficiency of perovskite solar cells.
Highlights
Since the rst demonstration in 2009 1 of solar cells using a semi-conductor from a class of materials known as metalhalide perovskites, perovskite solar cells have been the subject of intense investigation as candidate materials to drive further growth in the photovoltaics (PV) industry
The results reported by the other participants are distributed about the NREL and CSIRO values with varying agreement, which we attempt to explain based on the measurement technique employed by each participant
We identify the most important practices as those, which, when absent, are associated with the largest discrepancies from the results reported by CSIRO and NREL, which followed all practices
Summary
Since the rst demonstration in 2009 1 of solar cells using a semi-conductor from a class of materials known as metalhalide perovskites, perovskite solar cells have been the subject of intense investigation as candidate materials to drive further growth in the photovoltaics (PV) industry. As PV devices are sensitive to operating conditions, such as irradiance, device temperature, solar spectrum and angle of incidence, the PV community has adopted a convention of reporting device performance at xed conditions, known as the standard test conditions (STC), to enable fair comparisons between devices. A central metric used by researchers to quantify PV performance at STC is the current–voltage characteristic, or I–V curve. This curve expresses the electrical current, and by extension, the power, that can be generated as a function of the potential difference (voltage) across the device electrodes. Several important performance parameters can be obtained from I–V curves, in particular, the voltage and current at which the maximum power can be produced by the solar cell, referred to as the maximum power point (MPP). Knowledge of the I–V curve can provide valuable information on the physical mechanisms governing power generation and is important for control systems for deployed devices
