A low temperature coefficient, a favorable spectral response and high efficiency under low light conditions are the reason for excellent energy yields and hence low levelized costs of electricity under most climatic conditions.
Furthermore, the thin film module design based on monolithic interconnection results in intrinsically reduced sensitivity to shading. Lower temperature coefficients, higher shading tolerance and a good low light performance are also key requirements for building integrated PV applications.
