For higher-efficiency solar cell structures, such as the Passivated Emitter Rear Contact (PERC) cells, to be fabricated in a manufacturing environment, potentially low-cost techniques such as inkjet printing and metal plating are desirable. A common problem that is experienced when fabricating PERC cells is low fill factors due to high series resistance. This paper identifies and attempts to quantify sources of series resistance in inkjet-patterned PERC cells that employ electroless or light-induced nickel-plating techniques followed by copper light-induced plating. Photoluminescence imaging is used to determine locations of series resistance losses in these inkjet-patterned and plated PERC cells.

The effect of different meteorological conditions on solar cell outputs has been investigated, using a model for a solar cell (p-on-n or n-on-p) which incorporates surface recombination, surface region electric field and series resistance. Two ways of defining ‘ clear ’ and ‘ cloudy ’ conditions have been used, and by interpolating between them we have constructed two continuous ranges of meteorological conditions. The optimum achievement of a hypothetical range of substances X( E g ) which have an energy gap E g , but otherwise all have silicon material parameters, have been determined for each of the meteorological conditions mentioned above. The optimum material, X , for U.K. conditions is found to be X (1.78eV) rather than silicon which is X (1.12eV). However, its translation into a real material or its low-cost production are not considered here.

Thin-Film Silicon PV TechnologyThin-film silicon solar cell technology is one of the promising photovoltaic technologies for delivering low-cost solar electricity. Today the thin-film silicon PV market (402MWpproduced in 2008) is dominated by amorphous silicon based modules; however it is expected that the tandem amorphous/microcrystalline silicon modules will take over in near future. Solar cell structures based on thin-film silicon for obtaining high efficiency are presented. In order to increase the absorption in thin absorber layers novel approaches for photon management are developed. Module production and application areas are described.

Inkjet Printhead

Abstract Recently, the three-dimensional (3D) printing technique has attracted much attention for creating objects of arbitrary shape and manufacturing. For the first time, in this work, we present the fabrication of an inkjet printed low-cost 3D temperature sensor on a 3D-shaped thermoplastic substrate suitable for packaging, flexible electronics, and other printed applications. The design, fabrication, and testing of a 3D printed temperature sensor are presented. The sensor pattern is designed using a computer-aided design program and fabricated by drop-on-demand inkjet printing using a magnetostrictive inkjet printhead at room temperature. The sensor pattern is printed using commercially available conductive silver nanoparticle ink. A moving speed of 90 mm/min is chosen to print the sensor pattern. The inkjet printed temperature sensor is demonstrated, and it is characterized by good electrical properties, exhibiting good sensitivity and linearity. The results indicate that 3D inkjet printing technology may have great potential for applications in sensor fabrication.

Abstract Conventional series resistance imaging methods require electrical contacts for current injection or extraction in order to generate lateral current flow in the solar cell. This paper presents a new method to generate lateral current flow in the solar cell without any electrical contacts. This reduces the sample handling complexity for inline application and allows for measurements on unfinished solar cell precursors.
