DECLARATION ii I, MARASHA TAPESANA declare that: this is my original work and it had not been submitted to this or any other University. Signature…………………………. Date…………………………………… iii DEDICATION This study is dedicated to my loving wife Beatrice Mabhiza, my mother and my children; Rutendo, Anotida Mufaro and Anashe Marasha. They always supported me throughout the study. Sometimes I had to sacrifice family time with them but were always appreciative. iv ACKNOWLEDGEMENTS I acknowledge the following people who rendered invaluable information as I was carrying my study; Mr Ndlovu my supervisor for the relentless support and guidance throughout. Mr Mnyati and all the teachers of Gutu High School. Mr Masinire the Administrator of Gutu Mission Hospital. Mr Munamati for supplying me with helpful information about learners’ conceptions. The pupils and all the people who were involved in the study in one way or another. The research could not have been successful without the help of all these people. v ABSTRACT This study is an assessment of misconceptions of cells in pupils at Gutu High School. The researcher was interested in establishing if these misconceptions exist. The researcher also wanted to find out causes of these misconceptions and their effects to implementation of solar cells to communities in Gutu District. In this study learners at Gutu High were used as a sample to collect data. It was discovered, through literature review and the actual investigation that misconceptions really exist. It was found out that above 50% of the sample had misconceptions, and the misconceptions exist strongly in learners with a town background. The causal of these misconception were knowledge gap. Only 43% of the sample had better knowledge about solar. Another causal of the misconceptions was found out to be the syllabus coverage on solar cells. This study would add a lot of information to the existing board of knowledge regarding the same concept. As a result teachers at Gutu High could be helped in teaching solar energy and solar cells. vi TABLE OF CONTENTS Contents APPROVAL FORM ...................................................................................................................................... i RELEASE FORM .......................................................................................................................................... i DECLARATION .......................................................................................................................................... ii DEDICATION ............................................................................................................................................. iv ACKNOWLEDGEMENTS .......................................................................................................................... v ABSTRACT ................................................................................................................................................. vi TABLE OF CONTENTS ............................................................................................................................ vii LIST OF TABLES ........................................................................................................................................ x LIST OF FIGURES ..................................................................................................................................... xi CHAPTER 1 ................................................................................................................................................. 1 INTRODUCTION ........................................................................................................................................ 1 1.1 Introduction. ............................................................................................................................................ 1 1.2 Background ............................................................................................................................................. 1 1.3 Statement of the problem. ....................................................................................................................... 3 1.4 Hypothesis............................................................................................................................................... 3 1.5 Research Questions. ................................................................................................................................ 3 1.6 Assumptions ............................................................................................................................................ 4 1.6 Significance of study ............................................................................................................................... 4 1.7 Limitations of the study. ......................................................................................................................... 4 1.8 Delimitations of the study. ...................................................................................................................... 5 1.9 Definition of terms (Dictionary of science, 2000) .................................................................................. 5 1.10 Summary. .............................................................................................................................................. 5 CHAPTER 2 ................................................................................................................................................. 7 REVIEW OF LITERATURE ....................................................................................................................... 7 2.1 Introduction. ............................................................................................................................................ 7 2.2 Misconception on Solar PV Cell. ............................................................................................................ 7 2.4 How a solar cell work. .......................................................................................................................... 10 2.5 Types of Solar Panels ............................................................................................................................ 11 2.5.2 Advanced Mono Crystalline .......................................................................................................... 11 2.5.3 Poly Crystalline (polycrystalline c-Si) ........................................................................................... 11 vii 2.5.4 Thin Film -

  • The Institutional and Socio-Economic Constraints to Smallholder Tobacco Production and Marketing in Mount Darwin District of Zimbabwe: the Value Chain Approach

P Bag X1314, Alice 5700, Republic of South Africa This research was financed by the Govan Mbeki Research and Development Centre. Abstract This study used the value chain approach to identify the institutional and socio-economic constraints to tobacco production and marketing in Mount Darwin District; Zimbabwe. Three hundred and eighty farmers were randomly sampled for the study. Key informant interviews were used to collect data from input suppliers, contractors, buyers, auction floors, the Tobacco Industry Marketing Board, EMA and government extension staff. Data was analysed using descriptive statistics and the Pairwise ranking matrix. Results from the study identified shortage of foreign currency and high transport costs as the major constraints affecting input suppliers. Dry spells, labour shortages, high inputs costs, fuel shortages, pests were some of the farmers’ constraints to tobacco production. Some of the major marketing constraints affecting the smallholder farmers included low producer prices, high transport costs, theft in transit and exploitative prices offered by tobacco merchants. Auction companies cited viability challenges due to declining tobacco volumes sold through auction floors.
