Book Description
The book addresses the problem of passivation at the surface of crystalline silicon solar cells. More specifically, it reports on a high-throughput, industrially compatible deposition method for Al2O3, enabling its application to commercial solar cells. One of the main focus is on the analysis of the physics of Al2O3 as a passivating dielectric for silicon surfaces. This is accomplished through a comprehensive study, which moves from the particular, the case of aluminium oxide on silicon, to the general, the physics of surface recombination, and is able to connect theory with practice, highlighting relevant commercial applications.

Book Description
Solar cells are semiconductor devices that convert light photons into electricity in photovoltaic energy conversion and can help to overcome the global energy crisis. Solar cells have many applications including remote area power systems, earth-orbiting satellites, wristwatches, water pumping, photodetectors and remote radiotelephones. Solar cell technology is economically feasible for commercial-scale power generation. While commercial solar cells exhibit good performance and stability, still researchers are looking at many ways to improve the performance and cost of solar cells via modulating the fundamental properties of semiconductors. Solar cell technology is the key to a clean energy future. Solar cells directly harvest energy from the sun’s light radiation into electricity are in an ever-growing demand for future global energy production. Solar cell-based energy harvesting has attracted worldwide attention for their notable features, such as cheap renewable technology, scalable, lightweight, flexibility, versatility, no greenhouse gas emission, environment, and economy friendly and operational costs are quite low compared to other forms of power generation. Thus, solar cell technology is at the forefront of renewable energy technologies which are used in telecommunications, power plants, small devices to satellites. Aiming at large-scale implementation can be manipulated by various types used in solar cell design and exploration of new materials towards improving performance and reducing cost. Therefore, in-depth knowledge about solar cell design is fundamental for those who wish to apply this knowledge and understanding in industries and academics. This book provides a comprehensive overview on solar cells and explores the history to evolution and present scenarios of solar cell design, classification, properties, various semiconductor materials, thin films, wafer-scale, transparent solar cells, and so on. It also includes solar cells’ characterization analytical tools, theoretical modeling, practices to enhance conversion efficiencies, applications and patents.

Book Description
Surface passivation of silicon solar cells describes a technology for preventing electrons and holes to recombine prematurely with one another on the wafer surface. It increases the cell's energy conversion efficiencies and thus reduces the cost per kWh generated by a PV system.

Book Description
With the gradual decrease in silicon solar cell thickness, the overall efficiency has become more limited by the surface passivation. It has been recognized that the current dominant p-type silicon solar substrates will be replaced by the n-type materials. This thesis focuses on the properties of ALD aluminium-oxide layers, which is a promising dielectric material for the high efficiency n-type solar cells. Firstly, the impact of laterally non-uniform carrier lifetime on the determination of the lifetime from photoconductance-based measurements, based on the self-consistent method was investigated. An overestimation of the mean lifetime was simulated and experimentally confirmed, with the magnitude of the error mainly dependent on the distribution of the effective lifetime across the area sensed by the photoconductance coil. We investigated the passivation of ALD aluminium-oxide layers on both undiffused and boron diffused (111) and (100) oriented surfaces. It was found that the additional surface boron diffusion can reduce recombination at the alumina/Si interface. Aluminium-oxide passivated (100) surfaces displayed better passivation than (111) surfaces, which is due the finding that aluminium-oxide films on (100) orientated silicon form a higher negative fixed charge density than films on (111) samples, while there is not obvious difference on the interface state density. Aluminium-oxide/silicon-nitride stacks utilising an ultrathin aluminium-oxide layer were also studied concentrating on the correlation between the silicon nitride composition and its capping performance in terms of passivation and thermal stability. Excellent passivation was obtained by 1-nm-alumina/silicon-nitride stacks. The passivation performance of such stacks depends critically on both the alumina thickness and the silicon-nitride composition. It was found that to achieve low recombination factor with 1-nm-alumina/silicon-nitride stacks, the silicon nitride hydrogen concentration was required to be low, less than 8e21 per cubic cm. Both the alumina/Si interface and charge density of 1-nm-alumina/silicon nitride stacks can be impacted by the silicon-nitride capping layer. The outstanding passivation quality of 1-nm-alumina/silicon-nitride stacks is due to a favourable combination of both chemical and electrostatic passivation. Finally, the effect of humidity on aluminium-oxide passivated silicon samples was investigated. It was found that samples exposed to a saturated humidity ambient show a much higher degradation rate than those exposed to 85% relative humidity (RH). Moreover, the electrical resistance of aluminium-oxide film also decreased significantly following saturated humidity exposure. PECVD silicon nitride capping layers are effective at protecting aluminium-oxide films from damp-heat. Two degradation regimes are proposed to explain the degradation: (i) initial reversible degradation at shorter time exposures, which is ascribed to the loss of field effect passivation; (ii) severe degradation after longer term exposure, which is believed to be due to a substantial loss of chemical passivation with the generation of new species from the reaction of aluminium-oxide and water. The second regime was only observed for saturated humidity conditions.
