Santa Clarita, California [RenewableEnergyAccess.com] BioSolar, Inc., developer of a technology to produce thin film, flexible solar cells on bio-based plastic substrates, has successfully deposited Amorphous Silicon (a-Si) using a low temperature deposition process.“BioSolar has successfully completed the first step in constructing a bio-based solar cell by depositing amorphous silicon (a-Si) on a bio-based substrate,” said Dr. David Lee, BioSolar’s CEO. In the announcement, the company shed light on the primary challenge in resolving the properties of bio-based plastics: a low melting temperature relative to petroleum-based plastics. Unfortunately, chemical vacuum deposition (CVD) processes used to manufacture thin film solar cells generally occur at a much higher temperature than most bio-based films can withstand. “We are very pleased that our first bio-based film sample performed remarkably well in the initial chemical vacuum deposition (CVD) test,” said Dr. Lee. The company plans to continue working on the deposition process for the additional layers (including p-doped amorphous silicon, pure amorphous silicon, and n-doped amorphous silicon) to complete a working photovoltaic (PV) cell based on a bio-based plastic substrate.
