High efficiency MO-AI,O, cermet selective surfaces 96/04003 for high-temperature application Zhang, Q. C. er al., Solar Energy Materials & Solar Cells, Mar. 1996, 40, (l), 43-53. Highly efficient MO-Al,O, cermet solar absorbers have been designed with a numerical model and deposited experimentally. The typical film structure is an A&O, anti-reflection layer on a double MO-Al,O,, cermet layer on a MO or Cu metal thermal reflector. In numerical calculattons of the thermal emittance at high temperature for these selective surfaces, the temperature dependencies of the complex refractive indices of the metal reflector and cermet in the infrared region has been considered, and the dielectric functions of the cermet materials are evaluated using Sheng’s approximation.

Solar ‘95 Conference, Hobart, Tasmania, ANZSES, Box 124, Caulfield East, Vie. 3145, Australia. The paper presents the recent results in high efficiency silicon solar cell and module research. Hlgh-efflclency CVD multi-layer, single-layer thln96104005 film and thln slllcon solar cells Zheng, G. F. et al., Proc. Solar ‘95 Corzferettce, Hobart, Tasmama, ANZSES, Box 124 Caulfield East, Vie. 3145, Australia. The authors report on the high-efficiency chemical vapour deposition (CVD) multi-layer, single-layer thin-film and thin silicon solar cells. The CVD technique is a strong candidate for the cost effective deposition of thin silicon films. Hlstorlcal overview of bifacial solar cells 96/04006 Cuevas, A. Proc. Solar ‘95 Conference, Hobart, Tasmarlia, ANZSES, Bo.u 124, Caulfield East, Vie. 3145, Australia. This overview is based on the author’s direct involvement in the early development of different bifacial solar cells and their use in low concentration systems and albedo-collecting flat plate modules. lnvestlgatlon of control and slmulatlon of solar pro96iQ4007 cess heat plants using a flexible test facility Kohne, R. et al., Solar Energy, Feb. 1996, 56, (2), 169-182. An advanced control system for the operation of solar process heat plants and a simulation programme for the design are described. A flexible test facility was installed in order to qualify the control system and the simulation model. It consists of different small collector fields, two storage tanks, an auxiliary electric heater and an adjustable heat sink for simulating any load profile. The advanced control system provided a fast control of the necessary collector field outlet temperatures and an effective compensation for any disturbances. Is there enough sun In New Zealand for solar pas96lQ4000 slve houses? Bannister, P. and Guan, L. Proc. Solar ‘95 Corlfererlce, Hobart, Tasmania, ANZSES, Box 124 Caulfield East, Vie. 3145, Australia. It is widely accepted in New Zealand that passive solar architecture means large north facing windows and high internal mass. In practice, this often involves little more than north orientation and a concrete floor. However, simulation studies suggest that the benefits of this approach mpy not always be justified. The paper sets out a simple simulation study usrng the DOEl.l-E package which are used to compare lightweight and heavyweight constructions of similar insulation levels. 96104009 Issues affecting the scallng-up of solar thermal electrlclty plants Stein, W. Proc. Solar ‘95 Corlfererrce, Hobart, Tasmarria, ANZXS, Box 124, Caulfield East, Vie. 3145, Australia. The paper considers the possibilities for large scale solar thermal electricity plants using Australian-developed collectors. The deployment of largescale solar thermal plants is an attractive strategy for rapidly reducing greenhouse gas emissions. 96/04010 The Kalbarrl photovoltalc control system: Presentatlon of practical results Dymond, M. Proc. Solar ‘95 Cotlfererlce, Hobart, Tasmarlia, ANZSES, Box 124, Caulfield East, Vie. 3145, Australia. The Kalbarri Photovoltaic Project was commissioned in June 1995. The inverter has been operating successfully for much of the time since then. Tt was developed to operate on all four quadrants of real and reactive power and this is accomplished without the need for a battery bank. The paper briefly describes the control system used for real and reacrive power control. 96lO4011 Llfe cycle analysis of solar cell systems as a means to reduce atomospherlc carbon dloxlde emlsslons Komiyama, H. et al., Energy Co/lvers.

96104012 Measuring the spectral components of solar radiation Bason, F. Proc. Solar ‘95 Conferellce, Hobart, Tasmania, ANZSES, Box 124 Caulfield East, Vie. 3145, Australia. The measurement of the spectral components of solar radiation is a difficult and challenging aspect of solar radiation measurement with important environmental implications. The paper addresses the availability of reliable solar spectral radiation data and techniques for performing measurements. 96104013 A minimum achievable PV electrical generating cost Sabisky, E. S. Solar Energy Materials & Solar Cells, Mar. 1996, 40, (l), 55-70. The role and share of photovoltaic (PV) generated electricity in our nation’s future energy arsenal is primarily dependent on its future production cost. The paper provides a framework for obtaining a minimum achievable electrical generating cost (a lower bound) for fixed. flat-plate photovoltaic systems. A cost of 2.8cikWh (1990$) was derived for a plant located in Southwestern US sunshine using a cost of money of 8%. In addition, a value of 22ciwp (1990s) was estimated as a minimum module manufacturing cost/price. 96104014 Model to estimate performance of photovoltaic pump sets under dlfferent operating condltlons Dehmler, I. E. and Spencer, L. C. Proc. Solar ‘95 Conference, Hobart, Tasmania, ANZSES, Box 124, Caulfield East, Vie. 3145, Australia. Discusses the extension of an earlier computer model developed to provide improved assessment of photovoltaic pump performance. 96104015 Multlcrystalllne slllcon solar cells by llquld phase epltaxy Weber, K. J. et al., Proc. Solar ‘95 Confererlce, Hobart, Tasmania, ANZSES, Box 124, Caulfield East, Vie. 3145, Australia. The authors have investigated the growth of thin silicon films by liquid phase epitaxy (LPE) on single crystal and multicrystalline silicon substrates. The main difference between growth on multicrystalline substrates and growth on single crystal wafers is the development of grooves in the epitaxial layers in the vicinity of grain boundaries in the former case. These grooves have consequences for solar cell design. The influences of the LPE cooling rate and the substrate preparation on the epitaxial layer morphology and minority carrier lifetime have been determined. 96104016 Optics of a two-trough solar concentrator Richter, J. L. Solar Energy, Feb. 1996, 56, (2), 191-198. A linear focusing solar concentrator is described that uses two reflecting troughs, one is a large, stationary hemi-cyclinder and the other is small and tracks the sun. 96104017 A passlve solar unlverslty center Miller Thayer, B. Solar Today, Mar.-Apr. 1996, 10, (2), 34-36. Discusses a new classroom building at the University of Northern Iowa which uses daylighting and passive solar heating to save energy and money while teaching students and the public about energy and environmental concepts. 96104016 Phase change thermal storage for solar appllcatlons (Poster) Lee, T. and Garzoli, K. Proc. Solar ‘95 Co,lfererzce, Hobart, Tasmania, ANZSES, Rex 124, Caulfield East, Vie. 3145, Australia. Describes the recent progress in the research and analysis of phase change material heat storage for solar and other ambient energy applications at the ANU. 96104019 Phosphorous dlffuslon for the photovoltalc Industry Lye, C. C. et al., Proc. Solar ‘95 Conference, Hobart, Tasmania, ANZSES, Box 124, Caulfield East, Vie. 3145, Australia. Commercial silicon solar cells are considerably less efficient than laboratory cells. The aim of the authors’ research is to narrow this gap by optrmising the technologies used to fabricate them, in particular the diffusion of phosphorus to form their emitter regions. 96104020
Photovoltalcs: The future Is on Its way Green, M. A. Proc. Solar ‘95 Corrferer,ce, Hobart, Tasmania, ANZSES, BOA-124 Caulfield East, Vie. 3145, Australia. Of all renewable energy technology photovohaics has possibly the most to gain from the development and commercialisation of new ideas presently only in the conceptual or laboratory stage. Photovoltaics presently has a well established image of a high quality, high cost technology able to deliver in even the most demanding applications. The paper describes the work within the Author’s Centre directed at further improving performance features while reducing cost towards these lower limits. Also describes progress in the commercialisation of the Centre’s thin film multilayer cell technology in conjunction with Pacific Power via a newly incorporated company, Pacific Solar Pty. Ltd.
