Erfurt,
Germany: Ersol launches Micromorph Thin Film Module "Vega-T"
With
the start of series production, ersol Thin Film GmbH, a subsidiary
of ersol Solar Energy AG, Erfurt, is launching its first micromorph
thin-film module under the name Vega®-T. Micromorph technology
will enable initially an efficiency of approx. eight percent.
By
comparison, the efficiency level that is achieved with amorphous
thin-film modules is approx. six percent. In the next few years
an increase in the efficiency level of micromorph modules over
10 percent is planned.

In
the upcoming months production at ersol Thin Film will be converted
completely from amorphous to micromorph modules. Since January
2008, together with Schott Solar Thin Film GmbH, Jena, ersol has
been engaged in joint pre-competitive development of the new micromorph
thin-film technology. In contrast to the simple amorphous version,
the micromorph thin-film modules have a double-layer structure
consisting of an amorphous and a microcrystalline silicon layer.
Due to their different structures the two layers absorb different
wavelengths of the sunlight. Thus, a larger portion of the sun’s
light spectrum is used, giving added performance on the same area
compared to amorphous modules.
“The
area-related system costs can at the same time be lowered with
the higher level of efficiency. The introduction of micromorphous
tandem technology thus represents an important step towards cutting
PV electricity generation costs,” says Dr Christian Koitzsch,
TechnicalDirector of ersol Thin Film GmbH, stressing the benefits
of the new panel.
The
new module also attracts with its homogenous appearance. In contrast
to the dark brown amorphous modules, the black surface of micromorph
modules appeals to consumers, who in addition to higher performance
place special emphasis on aesthetics. Vega®-T has already been
certified by TÜV. Test certificates IEC 61646 and IEC 61730 have
been acquired. A future improvement is also planned. The Vega®-T
plus will be based on a toughened front glass.
