In this video I show how I made my colourful DIY Silicone Wedding Rings. There are loads of reasons why people want to wear a silicone ring over a metal one, if you work with your hands or do lots of sport for example. For full written instructions head over to my instructables page.

The heterojunction technology combines the advantages of crystalline silicon solar cells and thin film technologies enabling solar cell to reach higher degrees of efficiency at a lower cost of production.
This movie shows you the process of manufacturing solar cells with heterojunction technology:
Texturing
For high efficiency HJT cells, damages from cutting have to be completely removed and a special texture created by wet chemical processes. The wafers are also put through a special cleaning process.
PECVD Coating
The surface of the cell is passivated in order to prevent energy loss within the cell. The intrinsic and amorphous silicon layers are separated without cross-contamination, thus achieving passivation with a high longevity.
PVD Coating
A sputter process is used to apply a TCO layer to the front and back of the wafer which serves as an antireflection layer.
Printing
Screen printing is used to print the contacts on the front and back sides of wafers with silver paste.
Curing
Curing printed HJT cells is a simple thermal process in order to outgas the solvents within the low temperature paste.
Testing & Sorting
Meyer Burger offers leading measurement procedures for the precise testing of high capacitance HJT cells which require a measurement speed of 400–600 ms.
