Dr. Helmut Hoegl's Twin Solar Cell
The Twin Solar Cell, unlike
common flat photovoltaic cells, is characterized by its longitudinal (i.
e. wire-like) cell elements which can be arranged in nearly every conceivable
shape and size.
Producing Twin Solar Cells
is simple. They consist of silicon coated steel wire or copper-indium-diselenide
coated copper wire. The metal wires operate as internal electrodes and carry
p-n or n-p layers.
Advantages of the Twin
Solar Cell in comparison to ordinary photovoltaic cells:
Areas of application: tile like panels
on roofs, along or above country roads, motorways, railways, and agricultural
and urban fencing etc.
- nearly 100 % more efficient due
to their ability to absorb light from all directions (as opposed to flat
- about 90 % cheaper in production
due to low-cost components and modern wire and band production and coating
- fits to all surfaces of any imaginable
As of today, the Twin Solar
Cell is available in samples only. Extensive laboratory measurings and calculations
have been conducted and documented.
Provided the photovoltaic
properties of plastics can be exploited for the production of solar cells,
it would also be possible to develop photovoltaic textiles (i. e. "solar
blankets", truck hoods, indoor and outdoor curtains, special clothing).
Dr. Helmut Hoegl was born
in Germany in 1926. He is a diplomaed chemist and a renowned inventor (was
awarded the Diesel medal for inventors in silver in 1990). In the late fifties,
Dr. Hoegl discovered the photovoltaic properties of polymers and, while working
for Kalle Co. (Wiesbaden, Germany), invented the photovoltaic substance that
today is used in virtually every copying machine and laser printer.
Thereafter, Dr. Hoegl joined
and later headed the Battelle Institute in Geneva until 1976. His projects
include the development of catalysts for the production of polyoleofins and
highly sensitive organic synthetic conductors and the development of new
synthetic films for use in cars, office supply products, private households
and construction site equipment.
Since the eighties, Dr.
Hoegl has also been conducting research as a free scientist on the "Elfino
Theory" (dealing with the nature of energy) and "Monetary Energetics" (energy
as a measure of cash value).
The Twin Solar Cell was
invented in 1985. It has been patented in the US, in Japan, and in Germany.
The patent for the European Union is pending.
- US patent no. 4913744 (April 1990)
- German patent no. 3700792 (April
- Japanese patent no. 2683772 (August
- European patent to be granted soon
