 VHF-Technologies SA was founded in February 2000 as a high-tech start-up company. The core business are customised flexible solar cells (photovoltaic cells) which are manufactured on a plastic substrate.

To start with, I will review some reasons, why I do care about renewables, why I do believe there is a business opportunity within renewables and finally, why the photovoltaic industry has to my belief, a strong chance to succeed within the next 10-20 years on the very large scale. To further illustrate this, let me quote the bank Dresdner Kleinwort Wasserstein on a study published in June 2001: "Since 1996, industry shipments of photovoltaics have increased at a compound annual growth rate of 31% and are expected to continue growing at 30% per year for the next ten years, out stripping even the wind market growth. The installed base is now over 1 GW, with 288 MW shipped in 2000, up 43 % on the previous year."

The physical reasons why the photovoltaic transformation from light energy to electrical energy occur may be found today in every physics textbook. Also, looking at PV-conferences, there is a large amount of papers dealing with one or the other detail e.g. how to further increase the conversion efficiency of such a device.
I will keep this part very short and focus on our choice of material (a-Si:H), the technology employed (VHF-PECVD), as well as the cost aspect of using one or the other substrate and encapsulation material. This technical part should give enough knowledge to understand why we decided to found our own company with this approach and what our goals will be on the long run.

To conclude, I will show how we made our company: the early steps before actually founding the company, the first two years, where we are now and where we want to go. Last but not least I'll try to convince those fostering the similar idea of creating their high-tech start-up that such an endeavour is not only 95% transpiration (in comparison to the 5% inspiration) but that you can also have some fun along the way!
