Scientists at Stanford have set a new efficiency record for storing solar energy using water - splitting chemistry . They captured and stored 30 % of the sun 's energy through stored hydrogen , exceeding the prior record of 24.4 % . " Improving efficiency has a remarkable effect on lowering efficiency , " said associate professor Thomas Jaramillo , the team lead . The next stage is to reduce the cost of the triple - junction solar cells and batteries , including platinum .
