The optical detector further includes a module configured to output an indication of the intensity of the incident light according to a fourth spectral response function based on each of the first photocurrent, the second photocurrent, and the third photocurrent..

Thin film solar cell structure
A thin film solar cell includes a protection layer, a substrate and a photovoltaic conversion structure having a stack of one or several of non-planar light absorption layers, a first conductive layer being light transmissive and a second conductive layer being at least partially transparent or totally reflective. When the second conductive layer is totally reflective, it reflects the sunlight to the adjacent part of the thin film solar cell, proceeding another photovoltaic conversion and generating electric power again.
