  • Conductive paste based interconnection for photovoltaic modules

    We proposed low-temperature interconnection method using conductive paste (CP) for photovoltaic modules with thin c-Si cells. The advantage of CP approach is significantly reduced thermo-mechanical stress, as a result of the low tabbing process temperature (<; 150 °C). The resistivity loss induced by CP based approach is in the same range of module integrated by high temperature tip contacted soldering. Furthermore, thermal cycle and mechanical load tests confirm that CP provides stable interconnection between cell and module (degraded only 0.6%). Hence, unique traits of CP approach indicate that CP soldering is a production-ready alternative for interconnecting thin cells.

  • Performance and reliability evaluation of concentrated photovoltaic (CPV) power plants

    Performance and reliability evaluation and analysis of three concentrating photovoltaic (CPV) systems or power plants are presented at the string levels excluding the thermal and module level analyses. These plants are located in Arizona and were commissioned in mid-2012 (about 2 years old). The strings in all three power plants are operating between 79% and 0% of the rated capacity, and the average string operating capacity is only 34%. This paper indicates that the primary reason for power drop or complete loss of power in these CPV plants is due to misalignments in the tracking system. It was found that due to thermal stressing, wind loading, and tracker drift, tracking misalignment challenging the tracker controller was the most severe issue for performance drop or complete loss. This paper indicates that the reliability issues that need to be addressed by the CPV industry are not just on the cell level, but also on the precision of the systems' tracking.

  • Measurement of temperature coefficient of photovoltaic modules in field and comparison with laboratory measurements

    The performance of photovoltaic modules depends on temperature and irradiance. It is necessary to translate the measured I-V characteristics to standard test condition for assessing degradation, and such translations require temperature coefficients for voltage and current. Prediction of the annual energy yield also requires knowledge of the temperature coefficients. IEC 60891 provides a standard procedure for measurement of temperature coefficients and this methodology has been utilized to obtain the temperature coefficients of modules of different PV technologies, both in laboratory and in the field. Comparison of the values obtained in the field with those of the laboratory show good conformance. Also the variation of the temperature coefficients with change in irradiance has been investigated.

  • Investigation on stability of halide treated PbSe quantum dot thin films for photovoltaic devices

    PbSe quantum dot solar cells (QDSCs) have great potential for low-cost, high performance photovoltaic devices because of the tunable band gap by wet chemical solution process and excellent performance with multiple exciton generation (MEG). Passivation of PbSe QDs against oxidation is essential for such devices, since the QD solid thin films suffer serious oxidation within hours and degradation in photovoltaic performance. We applied halide treatments directly on PbSe QD thin films and we confirmed the stability of the films has been improved to different extents. We discovered that fluorine treatment did not provide good stability. However chloride, bromide and iodide treatments all improved the stability of the thin films, while the difference is minor within the study period (5 days). We attribute the improvement in stability to the formation of a lead - halide thin layer on the QD surface that serves as a protective layer to oxidation.

  • An Overview of SMUD's Outdoor Photovoltaic Test Program at Arizona State University

    In 2005, Sacramento Municipal Utility District (SMUD) increased the number of grid-connected PV systems to approximately 1050 leading to an installed capacity of over 10 MW<sub>ac</sub>. As the only independent accredited design qualification laboratory in the United States, the Photovoltaic Testing Laboratory at Arizona State University (ASU-PTL) provides an independent performance data to SMUD verifying manufacturers' data. In addition to obtaining the initial performance data, this SMUD-ASU program conducts several reliability and durability evaluations through long-term outdoor testing and accelerated indoor testing. This reliability evaluation program provides information on the predicted performance degradation per year, expected seasonal performance fluctuation and susceptibility to known failure mechanisms. This paper presents and analyzes the results of outdoor tests conducted on 44 modules of three different PV technologies (mono-Si, poly-Si and a-Si) from eight different manufacturers over the exposure period of two to seven years

  • An evaluation method for smoothing effect on photovoltaic systems dispersed in a large area

    PV is expected as a major carbon-free primary energy source which is inevitable to proceed to a carbon-free economy. However, as a variable power source, the large PV's penetration into the power system may cause various kinds of power system operation issues and/or expansion needs. In order to technically-and economically-feasible solution for these issues and needs, it is quite important to quantitatively analyze and evaluate the variation of PV generation. This paper will present the smoothing effect of the total PV generation output in a broad area by means of the maximum output fluctuation as fluctuation index.

  • Swiss Energy Strategy 2050: Research on photovoltaic electricity production

    Research activities on electricity production from photovoltaics as carried out by the Photovoltaic Laboratory (PV LAB) at Bern University of Applied Sciences BFH, Burgdorf, Switzerland are presented. The activities are nested in one of the new Competence Centers for Energy Research set up by the Swiss Government in view of implementing the “Energy Strategy 2050”. Information on long-term energy yields is gained from measurements in a Swiss photovoltaic installation network. This unique network was started in the 1990s by the PV LAB, who today operates around 35 PV installations in Switzerland. The current research focus is on alpine sites as they produce a stable energy yield in winter. Photovoltaic-oriented buildings (PVOB) also contribute to electricity production in winter and form another research pillar of the PV LAB. In order to survey mounting work, the quality of PV modules in complex terrain or on façades of high-rising buildings, a new IR-multicopter was built.

The calibration result shows expanded uncertainty of 0.91% and desired results reproducibility for establishing on-site photovoltaic metrology traceability chain in China.

  • Research on the performance of induction- motor- based residential photovoltaic water pump system

    Performances of induction-motor-based residential photovoltaic water pump system (IMRPWPS) with low DC voltage input (24 V DC) are tested in laboratory under four different operation modes, such as efficiency of DC-AC converter with high-frequency DC-DC stage, machine-pump and overall system. By analysis of these experiment results, it is discovered that the operation head and voltage-frequency ratio of motor (U/f) have significant effect on the performances of IMRPWPS besides the configuration of system components. And the minimum unit water cost may not be reached only by the control strategy of maximum output power of the system. Hence, as for a certain site, the proper selection of characteristics of converter and motor-pump and optimal ratio of U/f is significantly important to improve the economic performance of the system.
