Currently, about 90% of the commercial solar cells are manufactured using silicon wafers, either single crystalline or multi-crystalline (Fig. 22.3 ). The dominance of silicon solar cells stems from the high efficiencies of Si PV modules with demonstrated long-term stability.
Recycling technology of silicon wafers from PV cells. Etching solutions need to be modified by the type of PV cells to be recycled. The 38% silicon loses during NaOH etching. The addition of surfactants improves the recovery of silicon.
The manufacturing of solar cells involves several toxic, flammable and explosive chemicals. Many of those components suppose a health hazard to workers involved in manufacturing of solar cells. Solar panels are often in competition with agriculture and can cause soil erosion.
Solar cells made from recycled wafers are comparable in efficiency to commercial solar cells and HF free. Recycled nano-silicon meets the requirements of expansion-resistant silicon anodes for LIBs, providing 1400 mAh∙g −1 capacity, and HF free. NaOH instead of KOH is more economical and HF free.
The use of hazardous, toxic, and flammable substances during solar cell or module manufacturing, even in small amounts, can present occupational and environmental hazards (Solar Energy Isn’t Always as Green as You Think 2014 ).
Silicon is an indirect bandgap material that is successfully used to make commercial solar cell modules for almost 4 decades. Several different silicon solar cell structures are designed and optimized for achieving high efficiency are emerged in the last 20 years. These structures are presented in Fig. 22.5.
