Serially Connected Micro Amorphous Silicon Solar Cells for Compact High-Voltage Sources

Abstract EN

We demonstrate a compact amorphous silicon (a-Si) solar module to be used as high-voltage power supply.

In comparison with the organic solar module, the main advantages of the a-Si solar module are its compatibility with photolithography techniques and relatively high power conversion efficiency.

The open circuit voltage of a-Si solar cells can be easily controlled by serially interconnecting a-Si solar cells.

Moreover, the a-Si solar module can be easily patterned by photolithography in any desired shapes with high areal densities.

Using the photolithographic technique, we fabricate a compact a-Si solar module with noticeable photovoltaic characteristics as compared with the reported values for high-voltage power supplies.
