摘要： A photovoltaic cell may include a hydrogenated amorphous silicon layer including a n-type doped region and a p-type doped region. The n-type doped region may be separated from the p-type doped region by an intrinsic region. The photovoltaic cell may include a front transparent electrode connected to the n-type doped region, and a rear electrode connected to the p-type doped region. The efficiency may be optimized for indoor lighting values by tuning the value of the H2/SiH4 ratio of the hydrogenated amorphous silicon layer.

摘要： A manufacturing method of an electrochemical sensor comprises forming a graphene layer on a donor substrate, laminating a film of dry photoresist on the graphene layer, removing the donor substrate to obtain an intermediate structure comprising the film of dry photoresist and the graphene layer, and laminating the intermediate structure onto a final substrate with the graphene layer in electrical contact with first and second electrodes positioned on the final substrate. The film of dry photoresist is then patterned to form a microfluidic structure on the graphene layer and an additional dry photoresist layer is laminated over the structure. In one type of sensor manufactured by this process, the graphene layer acts as a channel region of a field-effect transistor, whose conductive properties vary according to characteristics of an analyte introduced into the microfluidic structure.
