The rise of back contact cell architecture

Sometimes, progress involves looking backwards. In this case, a return to back contact solar cell architecture has resulted in improved efficiencies and reductions in cost.For a long time, solar cell efficiency gains have been the main means of improving module output power not only as an important performance attribute, but also as a sales metric. Higher module efficiency reduces the balance of system (BOS) costs, thus reducing the overall final PV system costs. After commercializing various cell technologies, leading PV manufacturers now are once again moving back to putting most or all contact ...
