Inc. an­nounced it has suc­cess­fully de­vel­oped a key com­po­nent made of earth-abun­dant ma­te­rial which will re­duce the over­all cost of its re­new­able hy­dro­gen pro­duc­ing tech­nol­ogy process.

Re­search at the Univer­sity of Iowa, US, pub­lished in Ad­vanced Sci­ence, high­lights the sci­en­tific team’s suc­cess­ful so­lar hy- dro­gen pro­duc­tion us­ing an earth-abun­dant hy­dro­gen-pro­duc­ing pho­toac­tive elec­trode, made pri­mar­ily of tin and sul­fur.

The team led by Prof. Syed Mubeen, Univer­sity of Iowa, de­vel- oped novel de­vice de­sign strate­gies to syn­the­size and sta­bi­lize SnS based semi­con­duc­tors for hy­dro­gen pro­duc­tion. These so­lar hy­dro­gen pro­duc­tion units were fab­ri­cated us­ing scal­able so­lu­tion­phase chem­i­cal syn­the­sis meth­ods and pro­duced hy­dro­gen in acidic me­dia, with cham­pion de­vices pro­duc­ing pho­tocur­rents with in­ci­dent pho­ton-to-cur­rent ef­fi­ciency of 12.7%.
