Latest Patents

Among Rajeewa's latest innovations is his work on monolithic multi-junction solar cells utilizing amorphous silicon combined with copper indium selenide (CIS) and its alloys. This invention allows for the production of efficient broader spectrum monolithic solar cells by coupling a CIS or CIGS polycrystalline semiconductor to an amorphous silicon semiconductor. The coupling process employs an n-type conductor, such as cadmium sulfide or microcrystalline n-doped amorphous silicon. Notably, cadmium sulfide can be deposited on the CIS or CIGS polycrystalline semiconductor through methods like solution growth, sputtering, or evaporation. Additionally, a transparent conductive oxide can be deposited on the cadmium sulfide using low pressure chemical vapor deposition. The deposition of both the microcrystalline n-doped amorphous silicon and the amorphous silicon semiconductor is achieved through enhanced plasma chemical vapor deposition, incorporating various forms of hydrogenated amorphous silicon.
