A solar cell substrate with thin film polysilicon. The solar cell substrate includes a substrate; a transparent conductive layer, formed on the substrate; a thermal isolation layer having inlaid conductive layers, formed on the transparent conductive layer; and a polysilicon layer, formed on the thermal isolation layer.

A communication system includes an echo canceller and double-talk detector. The echo canceller includes an adaptive finite impulse response filter that generates an adaptive filter weight vector. The double talk detector computes a squared norm of the filter weight vector and detects an increase of the squared norm in order to detect double-talk status. Upon detection of double-talk status, operation of the echo canceller is suspended.
