High‐precision alignment procedures for patterning processes in solar

In this paper, we demonstrate the alignment procedure approaches on "pPassDop" solar cells by adjusting a locally applied laser process to the directly following screen-printing step. This proof of principle includes both above-mentioned methods for coordinate determination in separate cell batches.

30μm fine-line printing for solar cells

The effect of texture size on printed line width is studied by changing etching condition for texturing to make a large texture (roughly 8μm) and a small texture (roughly 3μm) on mono-crystalline wafers. And, the proper adjustment on screen printing conditions are

High-aspect-ratio silver grids of solar cells prepared by direct

Reducing the width of conductive silver wires, increasing the aspect ratio, improving the utilization rate of silver paste, and enhancing the uniformity of silver wires are key issues that need to be addressed in the manufacture of solar cells. This article explores the feasibility of using glass nozzles to directly write ultra-high viscosity

Matching the Photocurrent of 2‐Terminal

Current and voltage matching via the adjustment of the cell width of perovskite and organic solar modules is experimentally demonstrated, enabling a higher-than-individual efficiency of 14.94% over Photocurrent matching in conventional monolithic tandem solar cells is achieved by choosing semiconductors with complementary absorption spectra and by

Impact of scribe width reduction on the back-contact

In this work, the back-contact insulation process (P3) for thin-film silicon modules was evaluated for substrate side laser scribing with 532 nm. A special emphasis was placed on the influence of the P3 scribe width reduction on the electrical properties of the solar module.

30μm fine-line printing for solar cells

Abstract: The width of screen printed lines can be decided by the emulsion opening of a screen mask of screen printing, but actually the printed width is very much affected by the roughness of a substrate and the rheology of the paste used. Finger lines of solar cells should be as narrow as possible to increase sunlight usage efficiency. Hence

Improving the irradiation resistance of inverted flexible 3J solar

With the development of space power technology, mainstream solar cells have evolved into gallium arsenide (GaAs) cells. The progress of metal–organic chemical vapor deposition (MOCVD) technology makes it more flexible for bandgap adjustment and promotes the generation of inverted metamorphic multi-junction (IMM) GaAs cells with higher theoretical

Progress with screen printed metallization of silicon solar cells

The trend to interconnect solar cells with up to 12 wires instead of six or less busbars/ribbons has opened up the opportunity to realize such fine line grids on cell level, as more ribbons/wires enable a sufficiently low series resistance contribution of the grid even at a substantially higher lateral finger resistance R L [32].

Ultraviolet line structuring of large solar wafers

We introduce a novel UV line structuring method using deformable mirror technology and freeform optics. This approach aims to improve processing times on large substrates, especially for M12 solar wafer processing. By using a freeform lens and a Zwobbel deformable mirror, we achieve extended processing fields and high scan frequencies.

I-V Curve Measurement | Diode, Solar Cell & Resistor IV Curves

It is a straight line which intercepts the origin and passes through Quadrants I and III - making a resistor a passive device. The current at each voltage is proportional to the resistance following Ohm''s law: I = V / R. Therefore, the gradient of the line is equal to 1 / R, enabling the resistance to be extracted from the I-V curve. I-V curve of an ideal resistor Diode. A diode is a
