Pss heterojunction solar cell with performance enhancement tao chen 1 2 hao guo 2 leiming yu 1 2 tao sun 2 and yu yang 2 1 school of physics and astronomy yunnan university kunming 650091 china. It is a form of photoelectric cell defined as a device whose electrical characteristics such as current voltage or resistance vary when exposed to light. The below diagrams show schematically how devices are built on the photovoltaic substrate.

2 3 contact mechanisms a good front contact of the crystalline silicon solar cell requires ag electrode to interact with a very shallow emitter layer of si. Crystalline silicon c si is the crystalline forms of silicon either polycrystalline silicon poly si consisting of small crystals or monocrystalline silicon mono si a continuous crystal crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells these cells are assembled into solar panels as part of a photovoltaic. Copper zinc tin sulfide czts solar cells. Iii v devices are known to yield some of the highest efficiencies in photovoltaics but the high cost of lattice matched substrates and metal organic chemical vapor.

The highest laboratory efficiencies for single crystalline silicon solar cells have been in the range of 26 7 28 40 41 while that of hybrid organic si scs have demonstrated up to 17 4 with n type si substrate and 20 6 with p type si substrate. Pss solar cell is an important alternative for photovoltaic device due to its anticipated high theoretical efficiency and simple manufacturing process. Individual solar cell devices are often the. A typical firing profile of a commercial crystalline silicon solar cell.

A thin film solar cell is a second generation solar cell that is made by depositing one or more thin layers or thin film tf of photovoltaic material on a substrate such as glass plastic or metal. Resistance the substrate resist ance the front contact resistance and the grid resistance. A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon. For free abrasive wire sawing process the material removal mechanism can be considered as lapping and the fixed.

The development of a cost effective high voltage tandem solar cell that can be grown directly on a silicon si platform can lead to a 34 increase in efficiency over the present best monocrystalline si laboratory device. Multi wire sawing process has been widely used for wafer slicing of silicon substrates for solar cells.
