IMPROVEMENTS IN CdS THIN FILM SOLAR CELLS.
Abstract:
The report is concerned with two areas in the cadmium sulfide solar cell development program 1 a program of flight panel construction for satellite and balloon testing of CdS solar cells and 2 a developmental effort for improving the stability and efficiency of the CdS solar cell. Experimental CdS solar cells panels are being tested on the OV1-13 and OV1-17 satellite experiments. The developmental effort was concentrated into the following areas 1 contact resistance measurements made on the CdS current collector grid adhesive, 2 an optimization of the CdS cell for good low light level performance, 3 an optimization of the Cu25 barrier formation process and 4 an investigation of copper nodules found on CdS cells that had been degraded in the open circuit voltage mode.
