Coordinating technology, policy, and business innovations The annual potential of solar energy far exceeds the world's total energy consumption. However, the vision of photovoltaics (PVs) providing a substantial fraction of global electricity generation and total energy demand is far from being realized. What technical, infrastructure, economic, and policy barriers need to be overcome for PVs to grow to the multiple terawatt (TW) scale? We assess realistic future scenarios and make suggestions… 
Terawatt-scale photovoltaics: Transform global energy
A future with ∼10 TW of PV by 2030 and 30 to 70 TW by 2050 is envisioned, providing a majority of global energy, and what is needed in research in PV performance, reliability, manufacturing, and recycling is summarized.
Low-Cost Harvesting of Solar Energy: The Future of Global Photovoltaics
Photovoltaics is currently experiencing a rapid global expansion into the Terawatt age, exceeding even the most optimistic predictions of experts just a few years ago. This is driven by innovations,

The role of photovoltaics in a sustainable European energy system under variable CO2 emissions targets, transmission capacities, and costs assumptions
PyPSA‐Eur‐Sec‐30 is an open‐source, hourly resolved, networked model of the European energy system that includes one node per country as well as electricity, heating, and transport sectors. The
On-grid batteries for large-scale energy storage: Challenges and opportunities for policy and technology
We offer a cross section of the numerous challenges and opportunities associated with the integration of large-scale battery storage of renewable energy for the electric grid. These challenges
Radical transformation pathway towards sustainable electricity via evolutionary steps
A LUT Energy System Transition Model is utilized to indicate that a carbon neutral electricity system can be built in all global regions in an economically feasible way but requires evolutionary changes for the following 35 years.


Technology advances needed for photovoltaics to achieve widespread grid price parity
This paper examines the impact of changes to key PV module and system parameters on the levelized cost of energy (LCOE) and the impacts on the 2015 baseline LCOE due to changes to each parameter are shown.
The capital intensity of photovoltaics manufacturing: barrier to scale and opportunity for innovation
Using a bottom-up cost model, we assess the impact of initial factory capital expenditure (capex) on photovoltaic (PV) module minimum sustainable price (MSP) and industry-wide trends. We find capex
Assessing the drivers of regional trends in solar photovoltaic manufacturing
The photovoltaic (PV) industry has grown rapidly as a source of energy and economic activity. Since 2008, the average manufacturer-sale price of PV modules has declined by over a factor of two,
Compendium of photovoltaic degradation rates
Published data on photovoltaic (PV) degradation measurements were aggregated and re‐examined. The subject has seen an increased interest in recent years resulting in more than 11 000 degradation
Monocrystalline CdTe solar cells with open-circuit voltage over 1 V and efficiency of 17%
CdTe solar cells have not reached their full efficiency potential, in part because their voltages have lagged behind those of cells made from other semiconductors. Zhao et al. report monocrystalline
