Deposition reactor HWCVD:
A hot wire assisted, chemical vapour deposition reactor
(HWCVD). The system consists of two HWCVD deposition chambers
(one for the intrinsic material and the other for the
doped) and a charge chamber where transparent oxidant
conductors may be deposited by means of magnetron sputtering. |
 |
Deposition
reactor HWCVD:
Single chamber hot-wire chemical vapour deposition (HWCVD)
reactor. The system allows depositing on large area substrates
and roll-to-roll deposition on flexible substrates. |
| 
Sputtering
system:
ATC ORION 8 HV sputtering system with three 3"
targets in confocal configuration, RF biassing of the
substrate and heater ut to 800ºC. |
|
Optical
transmittance system with X-Y positioning:
Automated setup for measuring optical transmittance
on samples up to 20 cm x 20 cm. Spectra are automaticaly
treated to obtain thickness and refractive index mapping. |
Photothermal deflection spectroscopy (PDS):
Photothermic deflection spectrometer (PDS). With this
technique, very weak optical absorption can be measured
permitting the study of states in the prohibited bands
of semiconductors. |
|
System for the analysis of the angular and spectral scattering
of light:
System for the analysis of light scattered by rough
surfaces as a function of the angle and the wavelength
of the light. These measurements are of great interest
for the study of structures used to improve the optical
confinement in thin-film cells. |
Cell characterisation system:
Cell characterisation system that permits measurement
of the spectral response and of the current-voltage characteristics
with variable illumination. |
|
LAMBDA 950 spectrophotometer:
Spectral range from 175 to 3300 nm with a resolution
of 0.05 nm in UV/Vis region and 0.20nm in NIR. Features
a 150 mm integrating sphere for measurement of total and
diffuse reflectance and transmittance. |
|
Monitoring
system for photovoltaic modules:
The monitoring systema for photovoltaic modules under
real conditions is located on the roof of the Physics
Faculty of the Universtity of Barcelona (latitude: 41.3844°N,
longitude: 2.1171°E). The system features several
electronic charge modules that track the maximum power
point (mpp) and acquires the I-V curve characteristics
every five minutes. Temperature of the modules and global
solar radiation on the plane of the modules are also recorded.
Climatic conditions are obtained from the weather station
of University of Barcelona.
