Microcrystalline Silicon Solar Cells: Effect of Substrate Temperature on Cracks

Single junction microcrystalline silicon solar cells presently reach confirmed efficiencies up to 10.1%. Further improvement on device quality is now necessary to continuously increase the electrical performances of the solar cells. Zones of porous material, called “cracks”, appear when the substrate, such as glass covered with zinc oxide (ZnO), is too “rough”. Previous works have demonstrated ...

Design of Iii-v Multijunction Solar Cells on Silicon Substrate

With looming energy crisis across the globe, achieving high efficiency and low cost solar cells have long been the key objective for photovoltaic researchers. III-V compound semiconductor based multijunction solar cells have been the dominant choice for space power due to their superior performance compared to any other existing solar cell technologies. In spite of unmatched performance of III-...

Silicon Heterojunction Solar Cells on N- and P-type Wafers

A systematic comparison of frontand rear-emitter silicon heterojunction solar cells produced on nand p-type wafers was performed, in order to investigate their potential and limitations for high efficiencies. Cells on p-type wafers suffer from reduced minority carrier lifetime in the low-carrier-injection range, mainly due to the asymmetry in interface defect capture cross sections. This leads ...

Silicon Solar Cells: Structural Properties of Ag-Contacts/Si-Substrate

The screen-printed silver (Ag) thick-film is the most widely used front side contact in industrial crystalline silicon solar cells. The front contacts have the roles of efficiently contacting with the silicon (Si) and transporting the photogenerated current without adversely affecting the cell properties and without damaging the p-n junction. Although it is rapid, has low cost and is simplicity...
