PV grid parity has been reached in the Gran Canaria island grid. To diminish the generating cost ($ 297.37/MWh on average in Canary Islands in 2013) the new Spanish regulation approved in August 2014 offer substantial incentives for PV investment in insular systems. However, many of the best locations for large PV systems are far away from substations. On the other hand, there are isolated villages...
This paper summarizes the Europe-Japan Collaborative Research Project on Concentrator Photovoltaics (CPV); NGCPV Project (a New Generation of Concentrator PhotoVoltaic cells, modules and systems. The aim of this project was to accelerate the move to very high efficiency and lower cost CPV technologies and to enhance widespread deployment of CPV systems. 7 European partners and 9 Japanese partners...
Ion-implantation offers numerous advantages (i.e. single side precise control and reproducibility of the dopant, simultaneous SiO2 passivation during annealing, no phosphosilicate glass formation) for solar cell manufacturing. Canadian Solar Inc. (CSI) has developed an average efficiency 19.23% blank emitter solar cell (156mm Cz) process. In order to improve the solar cell efficiency, focus is placed...
Global irradiance sensors supply essential information in the business of planning and operating PV Systems. Errors and uncertainty in irradiance measurements propagate to uncertainty about performance and profitability. PV Performance Labs initiated the PVSENSOR project in 2014 to more fully characterize commercial irradiance sensors, with the objective of reducing such uncertainties. In the first...
In this work we present a methodology to exploit the crack statistics of solar cells in PV modules assessed in field for simulating the power output of PV modules. The probability of crack and the type of crack depending on the position of the cell in the module are used to simulate a statistical distribution of modules constituted of cells represented by an extended two diodes model. The effect of...
Open circuit voltage of 960mV on chalcopyrite solar cell was achieved by pure-sulfide CuInGaS2 solar cell. Generally, high performance CuInGaS2 needs KCN-etching treatment to remove CuS layer, however, we could fabricate it without KCN-etching treatment. Additionally, Cd-free buffer layer was applied for current density improvement and the champion cell demonstrated over 14% efficiency. In this paper,...
To further increase the conversion efficiency of crystalline silicon solar cells it is vital to reduce the recombination losses between the photoactive part of the solar cell and the metal contacts. This is ideally achieved by fabricating contacts which passivate defects at the silicon surface while being simultaneously selective for only a single type of charge carrier, i.e. either electrons or holes...
To investigate efficiency and yield of most micro-inverters available on the world market in 2013-14, an outdoor test field on the University of Paderborn has been set up. The inverters have been fed by identical & calibrated crystalline silicon PV modules of 215 W at STC. To monitor accurately AC power output and yield, each of the micro-inverters has been equipped with a calibrated precision...
Close spaced sublimation (CSS) has attractive features for high-rate deposition of CdS/CdTe thin film solar modules. CSS has been successfully implemented in commercial production of CdTe solar panels with size of 0.6 m × 1.2 m and 1.2 m × 1.6 m. A CSS growth model is a useful tool to guide the CdTe thin film deposition and the design of CSS. In this paper, a growth model was developed for CdTe deposition...
The behavior of silicon bypass diodes for space solar cells was experimentally investigated at high temperatures up to 250 °C for the design of Japan's Mercury probe BepiColombo MMO. Though the reverse current increased to nearly 10 mA at 250 °C, the operation at such high temperatures did not permanently damaged the diodes. When the diodes were irradiated with protons and then kept at high temperatures,...
In this paper we will update our 2011–2013 study on the analyses of operational performance of grid connected residential PV systems in the Netherlands and other European countries. We focus on comparing Annual System Yield data from small and medium size installations. If irradiance data is available, Performance Ratio data are compared as well. We employ web scraping techniques to collect a large...
We report the results from a survey of commercial c-Si photovoltaic (PV) systems. These systems range in size from 1kw to 20MW representative of residential, commercial, and utility scale projects from newly commissioned to >25 years in operation. These results provide the industry with valuable PV system field experience and document PV module defects. Furthermore, a breakdown of module subcomponent...
We have studied the impact of threading dislocation density (TDD) on the performance of GaAs associated with the epitaxial growth on silicon (Si) substrate in either single-junction GaAs or dual-junction two-terminal GaAs/Si solar cell devices. The performance is measured under truncated spectrum due to the presence of internally lattice matched top GaInP filter with GaAs sub-cell. It is found that...
Cu2ZnSnSe4 (CZTSe) solar cells were prepared at high temperatures on Si/SiO2 sodium free substrate. Si/SiO2 was used as substrate to study the formation of CZTSe absorber without the possible influence of Na and for analyzing its compatibility with Si microelectronic technology. This substrate allowed reaching higher temperatures than the ones commonly used with soda lime glass (SLG). An efficiency...
