Energy saving is currently one of the most important lines of research,
considering the population increase and its inherent global energy demand. The
development of alternative non-polluting energy sources that are efficient and
energy-saving is also a priority challenge. Due its location on the globe, Mexico
represents the third country with the best capture of solar energy, one of the
most promising alternative energy sources, since it allows different forms of
capture and transformation. Consequently, the research group of “Electronics
and Systems” of FIUAEM together with the research group of CINVESTAV Mérida,
work atthe development of an electronic instrumentation system by controlling
the temperature and luminosity applied in the terminal phase (Light Soaking)
for the manufacture of CdS / CdTe solar cells in order to improve its efficiency.
Here is presented r the design and construction of a prototype that allows to
apply a temperature and luminous intensity inside a test chamber containing a
CdS / CdTe solar cell. In addition to allowing the user to program fixed values of
temperature and light intensity in a graphical interface, the proposed system
will allow the control of the values of both variables according to arbitrary curves
as a function of time. This versatility will allow to determine the parameters that
describe both functions (temperature and luminous intensity) in such a way that
it results in a greater efficiency of photovoltaic conversion measured in terms of
the current and the voltage that can produce a solar cell of CdS / CdTe during
the Light Soaking process, which in turn will result in a greater efficiency of
photovoltaic conversion of said cells installed in the field
