Tanzania: Materials Science for Solar Energy Conversion (TAN:01/2) Summary Thermochromic VO2 Films. Vanadium dioxide is a first order phase transition material that displays temperature dependent changes in structural, electrical and optical properties. VO2 can reversibly change from semiconductor to metallic phase when its temperature is raised beyond a critical point, reported to be ~ 68 oC. This transition temperature, Tc is closer to room temperature than for most other transition metal oxides. It is possible to reduce Tc through doping using Fe, Co, Ni, Mo, W, and Nb as dopants also by replacement of some oxygen by fluorine, introduction of stress by use of a suitable substrate or by applying an over layer. The phase transition is associated with large and sharp changes in resistivity, optical transmittance and reflectance especially in the near infrared and also a crystallographic transformation from monoclinic at low temperature to tetragonal at high temperature. VO2 films have a potential to be used as a thermo switch in energy efficient windows. Thus for example, glass windows coated with vanadium dioxide will transmit both the luminous and the infrared component of the solar radiation at lower temperature, but will be almost opaque to the infrared part of the solar radiation when the temperature is raised above the critical point, Tc. The transition temperature Tc at which VO2 switches from a low temperature semiconductor to a high temperature metallic state is too high (68 oC) for windows applications. For both metallic

and semiconductor phases of the films, the optical transmittance in the visible part of the solar spectrum is rather low, specifically < 45 %. More data will be sought for optical constants of the films prior to designing an antireflection coating whose role would be to increase the visible transmittance of the films. The antireflection layer may also act as a protective film against severe environmental conditions. In most of the previous studies, single layer films have been fabricated, but studies are underway to investigate multilayer VO2 films. A dielectric layer sandwiched between the VO2 films, may have an effect (including a strong angular sensitivity) on the optical properties of the films due to optical interfernce between the layers. There is also a possibility of reduction in the transition temperature due to strain that may be produced by the multilayers. Dielectric functions for the films will be determined by ellipsometry prior to doing theoretical modelling for single and multilayer structures for a few temperatures in the practical region (20 – 30 oC) For higher sensitivity and control there is a need for better temperature response between heating and cooling. This requires that thermal hysteresis is small like that of bulk VO2. The study intends to perform investigations on the optimal deposition conditions that may achieve this practical requirement. Furthermore the proposed study aims to investigate the microstructure of the films with a view to set a basis for explaining the thermochromism and aging affects observed in the previous studies. For example, although humidity was observed to age these films substantially, it is not known which phase is involved in the aging process. The study also intends to examine changes in film thickness through the transition and also perform Hall effect measurements through the transition in the semiconductor phase of the films. . Performance of Photovoltaic System This is a continuing work whose aim is to correlate the output power or the efficiency at different module temperatures and at various irradiation levels. The rate at which the module is heated by the solar radiation will enable us to study possible means/ways that could lower the maximum module temperature attained during the day. Thus a passive cooling device will be designed (in a form of fins) and will be bonded at the rear side of the module. A design, based on the heat-transfer model will be formulated in order to work out an optimum geometry and size of the metallic fins. Measurements similar to those made above will be done in order to evaluate the usefulness of the fins in attaining maximum output power of the module. Cu(In,Ga)Se2 solar cells Among outstanding thin film solar cells, Cu(In,Ga)Se2 solar cell is the real promising candidate. It has the highest laboratory solar cell efficiency at the moment. The cell has a very high stability against solar irradiation and humidity. Its chemical stability makes this type of a cell unique. A number of measures have been taken to explore the cell technology to the current level including the use of double layer ZnO:Al/ZnO window layers, optimization of Cu(In,Ga)Se2 absorber layer, the use of CBD CdS buffer layer and improvements of back contacts and grids. According to the authors who produced the current highest (18.8 %) solar cell efficiency, their results were improved by optimizing the window layers and back contacts. The way toward further improvement of the window layer is through the use of a transparent conducting material (TCO) with higher mobility than the

current ZnO:Al thin film. This can be achieved by using a dopant which is highly electronegative and whose atomic radius is close to oxygen (the substituted atom in ZnO to get doped ZnO). Boron is the only element that fulfils the mentioned dopant properties to ZnO to form ZnO:B. This study works toward the use of optimized ZnO:B as a transparent conducting material for Cu(In,Ga)Se2 solar cells. The optimization process of ZnO:B thin layers involves electrical, optical and structural characterizations. The equipment that are involved in this study program includes, the sputtering coating unit, four point probe, XRD, TEM, SEM, AFM, Lambda 9/900 spectrophotometer, alpha step thickness measurement machine and Vander Pawl method. Cu(In,Ga)Se2 solar cells will then be fabricated using the optimized ZnO:B and then characterized. Stability study will be studied too. The fabrication of Cu(In,Ga)Se2 solar cells using ZnO:B TCO from sputtered Zn:B and ZnO:B work is a new work to our knowledge and we are looking forward to promising results. Outreach Activities During the years (2007-2009), one member of the group (Prof Kivaisi) has participated in organising training courses for local technicians on Photovoltaic technology. The “Sida/MEM* Solar PV Project” and MEM/UNDP/GEF** “Transformation of the Rural PV Market in Tanzania” did request PV training experts from the University of Dar es Salaam to provide the requisite Technical Training on Solar PV Technology to a number of technicians and artisans situated in several regions in Tanzania. It is expected that after completion of the PV training course, the trainees would go back to their districts and work together with local PV dealers in an effort to support the private sector in the dissemination of PV technology to the local communities. Participants to the training workshops were technicians and artisans who have completed VETA electrical training course level one and are currently working as electricians in their respective districts/Regions. So far eight regions have been covered, including, Morogoro, Tanga, Pwani, Kigoma, Mtwara, Rukwa, Mbeya and Dodoma. All together a total of about 100 technicians/artisans have benefited for such trainings.
