Latest Patents

Kwok holds a patent for a non-vacuum method of manufacturing light-absorbing materials for solar cell applications. This invention describes a method of producing a p-type light-absorbing semiconductor known as copper zinc tin selenide/sulfide (Cu(ZnSn)(SSe)), abbreviated as CZTS, using electrochemical deposition. The method allows for the production of solar cells by combining CZTS with an n-type inorganic or organic semiconductor layer. Notably, this approach involves a one-step or a sequence of depositions using electroplating, which fabricates low-cost and large-area CZTS solar cells without the need for expensive and complicated deposition techniques or highly toxic and flammable chemicals. This innovation significantly reduces both the cost and energy requirements for solar cell production.
