Texturization is a process of producing the desired unevenness on the surface of solar cell. It is well known as a practical solution to the limitation. Front surface texture reduces cell reflectivity and contributes to more photocurrent generation within active materials.
These texturized surfaces with unique optical properties can be implemented as anti-reflective or light-trapping interfaces to reduce optical loss and thus enhance the efficiency of solar cells. Optical properties of texturized surfaces and applied examples are introduced in this review. Avoid common mistakes on your manuscript.
An average of 30% of the incident light is lost via reflection from the front surface of the silicon solar cell, thus reducing the cell's power conversion efficiency. Texturization is a process of producing the desired unevenness on the surface of solar cell. It is well known as a practical solution to the limitation.
Results show that the initial texturing topology and reflectivity is not affected by the subsequent rinses and the doping uniformity is also the same as with the standard chemicals.
