Low Cost Large Area Laser Beam Induced Current Measurement System for Characterisation of Photovoltaic Modules[ ]


Photovoltaic (PV) modules need to be free from current mismatch between cells for their optimal performance and longevity. Therefore, characterisation tools are essential for evaluation of the performance of individual cells in a PV module. In this study, a low cost, simple and handy large area laser beam induced current (LA-LBIC) measurement system was developed to assess the current levels of module cells. In this system, a laser source mounted onto a motorised scanning stage is used to illuminate a PV module, while measuring the module output current at different positions along the scanning line. The scan is executed across the module, perpendicular to the cells. The LBIC measurement is a non-destructive technique that produces a graphical representation of the photo-current with respect to position in a PV module. The line scan maps revealed the proportion of under-functioning cells to be 85.4% for single crystalline silicon (c-Si), 62.5% for multi-crystalline silicon (mc-Si) and 75% for amorphous silicon module (a-Si). Current variations (current mismatch) between the highest and the lowest performing cells were 99%, 97% and 90% for c-Si, mc-Si and a-Si respectively. Current variations within cells were 31%, 15% and 14% for c-Si, mc-Si and a-Si respectively. In all the different PV module technologies, variations in current between cells were significantly higher than within cells.

A Generalized Correlation for Predicting Gas Breakthrough Time[ ]


Numerous methods have been presented to avoid gas breakthrough because of coning. These approaches include: keeping oil production rates beneath a certain value, forming a gas-blocking region nearby the well by inserting crosslinking gels or creating perforation as far from the original gas-oil contact (GOC) as possible. In some cases, it is uneconomical to retain oil production rate below the critical rate. Perforating far above the GOC decreases the perforation interval length, thus, rises pressure drawdown nearby the bore hole. The increased pressure drawdown may increase gas coning. Since the fifties, the coning has been investigated broadly, but it is still difficult to answer to the following questions, how to perforate a well coming undergo to the coning? And what is the op-timum oil flow rate of the well?
