Abstract

We report the design and fabrication of transfer-printed flexible three-color multijunction 8 × 8 crystalline silicon membrane photodetector arrays. Based on the penetration-depth-dependent absorption of different wavelengths, filter-free color detection can be obtained via three junction photocurrent measurement. The optical measurements show good agreements with the optical behavior predicted by the design and simulation. No noticeable changes were observed in the device performance when it was operated in a bending state.
