Abstract
In India, the research on solar cells is b
e-
ing pursued in various scientific labor
a-
tories and industries; however, there is
no facility for the validation of s
o
l
ar cell
efficiency. Globally there are three re
c-
ognized ce
n
ters available for validation
of solar cell efficiency, namely
National
Renewable Energy Laboratory
(USA),
Fraunhofer
Physikalisch
-
Technische
Bundesanstalt
(Germany) and
Institute of
Advanced Indus
trial Science and Tec
h-
nology
(Japan).
In order to validate the
e
f
ficiency of the fabricated solar cells,
these have to be sent to one of the
above
-
mentioned centers and this process is not
only e
x
pensive but also time consuming.
For the validation of e
f
fic
iency of such
devices
,
it requires calibration of various
individual parameters involved in mea
s-
urement of efficiency, such as, light
source, cu
r
rent/voltage source
-
meter,
temper
a
ture sensors and active area of
device.
