Electrochemical Recycling of Photovoltaic Modules to Recover Metals and Silicon Wafers

dedekind modules and dimension of modules

در این پایان نامه، در ابتدا برای مدول ها روی دامنه های پروفر شرایط معادل به دست آورده ایم و خواصی از ددکیند مدول ها روی دامنه های پروفر مشخص کرده ایم. در ادامه برای ددکیند مدول های با تولید متناهی روی حلقه های به طور صحیح بسته شرایط معادل به دست آورده ایم و ددکیند مدول های ضربی را مشخص کرده ایم. گزاره هایی در مورد بعد ددکیند مدول ها بیان کرده ایم. در پایان، قضایای lying over و going down را برا...

RECYCLING OF CdTe PHOTOVOLTAIC MODULES: RECOVERY OF CADMIUM AND TELLURIUM

Research on recycling of CdTe PV modules and manufacturing waste aims in optimizing the separations and recovery of glass, cadmium and tellurium while minimizing life-cycle emissions and energy use, under the constraint of low cost (e.g. a few cents per watt). The major tasks of our research are: a) Cleaning of glass from the metals and recycling of glass; b) separation of Te from Cd and other ...

Life Cycle Design of Amorphous Silicon Photovoltaic Modules

The life cycle design framework was applied to photovoltaic (PV) module design. The primary objective of this project was to develop and evaluate design metrics for assessing and guiding the improvement of PV product systems. Two metrics were used to assess life cycle energy performance of a PV module: energy payback time and electricity production efficiency. These metrics are based on materia...

Field Performance Measurements of Amorphous Silicon Photovoltaic Modules in Kenya

Our research team measured the performance of 130 amorphous silicon (a-Si) photovoltaic (PV) modules and 17 crystalline PV modules at 145 homes in rural Kenya. We also purchased 14 a-Si modules in Nairobi that we tested at outdoor testing facilities in the US and Kenya. We used an outdoor IV test method that has an accuracy of ±5% and a repeatability of ±5% for clear sky conditions. The large m...
