Thin film PV shows substantially different degradation trends compared to the classical crystalline devices. This chapter relates that difference to the physics of thin film PV. It begins with a historically important assessment that crystalline devices degrade mostly due to accumulation of structural defects, either native or
Customer ServiceThin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers ( nm ) to a few microns ( μm ) thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to

Customer ServiceCdTe thin film solar cells grew out of these II-VI semiconductor beginnings, in-parallel with CdS efforts at General Electric and the US Air Force, as Loferski [52] had realized that the CdTe bandgap was well-matched to the solar spectrum. Also, CdTe could be doped both n- and p-type – a factor that has not received as much attention in the PV context.

Customer ServiceThe performance degradation behavior of the PV cells under various impact velocities is observed. The conversion efficiency sharply decreases with impact velocity increasing. The critical impact velocities for the initiation and total failure of the PV cells are determined. 3.
The damage behavior affects the performance of PV cells in field usage. Obviously, more severe degradation of electricity performance will be triggered with higher impact velocity and number densities of particles. The degradation of conversion efficiency is also supportive to understand the role of the mechanical impact.
The crack morphologies of the damaged PV cells are simply illustrated in Table 1, including the damaged grid line, the partly peeled-off PV cell materials, some apparent cracks in the PV cell, and total fragmentation. The damage behavior affects the performance of PV cells in field usage.
Thin-film multi-junction photovoltaic (PV) cells made from the compounds of III–V materials have been widely adopted due to their high light-electricity conversion efficiency and low areal mass density 1, 2.
Therefore, it is crucial to characterize the mechanical damages due to particles’ impact on the PV cells to further reveal the mechanisms of performance degradation. The damage behavior of the PV cells in such an impact environment can be classified into three modes.
The damage behavior of the PV cells in such an impact environment can be classified into three modes. The first damage mode, denoted by Mode I, is the rupture of the conducting grid lines by impact loadings as depicted by the green arrows in Fig. 6.
