Photovoltaics (PV) has become the cheapest source of electricity in many countries and every two years, the capacity is roughly doubled, but it is uncertain if this growth will be sustained. If potential barriers to deployment are addressed, PV could cost-competitively supply 30-50% of global electricity by 2050. Two potential barriers which need to be addresses could hinder continued growth: integration challenges, as many options exist, and the financing costs require international cooperation.
