The invention relates to a photovoltaic module comprising a front bonding layer to photovoltaic cells are attached, such that the front side of each photovoltaic cell is attached to the front bonding layer. The photovoltaic module further comprises an open container containing a dielectric heat transfer fluid. The container comprises a bottom wall and side walls wherein the front bonding layer is disposed on top of the open container in order to close the container such that at least part of the backside () of each photovoltaic cell is in contact with the dielectric heat transfer fluid.

Methods of recycling silicon swarf into electronic grade polysilicon or metallurgical-grade silicon are described herein are described. In an example, a method includes cutting a silicon ingot and recovering silicon swarf having a first purity from the cutting process. The recovered silicon is purified in an upgraded metallurgical silicon process to produce electronic grade polysilicon particles having a second purity higher than the first purity. The upgraded metallurgical silicon process can include dissolving the recovered silicon particles in a molten aluminum metal smelt.
