Multi-objective evolutionary optimization of photovoltaic glass

PV glass generates 54 kWh, 140.8 kWh, 241.3 kWh, and 182 kWh of electrical energy for winter, spring, summer, and fall seasons. Some PV glass may store heat during the power conversion and increase indoor air temperatures. However, the implemented PV glass has Low-E coatings that act as a thermal insulation layer for the window.

For instance, the fracture strength of 2.89 mm fully tempered solar photovoltaic glass with glaze in the four-point bending test measures approximately 104 MPa, whereas the fracture strength of 1.55 and 1.86 mm semi-tempered solar photovoltaic glass is only
