ALTERNATIVE ARCHITECTURE FOR SOLUTION PROCESSED THIN FILM SOLAR MATERIALS

A variety of competing semiconductor materials are used to create p-n solar cells. Currently silicon solar cells dominate more than 90% of the solar market. The major competitors to silicon solar cells are inorganic thin-film solar cells, mainly cadmium telluride and copper indium gallium sulfide. These materials evolved from initial devices based off of cadmium sulfide. All of the non-silicon commercial cells still use cadmium sulfide in their production, which is of concern due to the toxicity of cadmium and limits their application, especially in Europe due to the E.U. Restriction of Hazardous Substances directive. If these devices are to remain market competitive, increased cost efficiency and the removal of cadmium are necessary

Effectiveness and improvements of silicon and cadmium sulfide solar cells studied for space power system application

Radiation resistance of thin-film solar cells for space photovoltaic power

Copper indium diselenide, cadmium telluride, and amorphous silicon alloy solar cells have achieved noteworthy performance and are currently being studied for space power applications. Cadmium sulfide cells had been the subject of much effort but are no longer considered for space applications. A review is presented of what is known about the radiation degradation of thin film solar cells in space. Experimental cadmium telluride and amorphous silicon alloy cells are reviewed. Damage mechanisms and radiation induced defect generation and passivation in the amorphous silicon alloy cell are discussed in detail due to the greater amount of experimental data available
