“…A field study in Arizona US showed that an a-Si module had 30% more battery charging capacity (amp-hrs) compared to a c-Si module of the same STC power rating. 68 Another reason for the higher energy rating is the thermal annealing of light-induced defects which gives a-Si has its seasonal high efficiency in the summer when the warm days and nights help to anneal light-induced defects, and the solar irradiance is highest. Interestingly, the temperature coefficient for single, double or triple junction a-Si modules is approximately the same.…”

Thin film solar cells (TFSC) have passed adolescence and are ready to make a substantial contribution to the world's electricity generation. They can have advantages over c-Si solar modules in ease of large area, lower cost manufacturing and in several types of applications. Factors which limit TFSC module performance relative to champion cell performance are discussed along with the importance of increased throughput and yield. The consensus of several studies is that all TFSC can achieve costs below 1 $/W if manufactured at sufficiently large scale >100 MW using parallel lines of cloned equipment with high material utilization and spray-on encapsulants. There is significant new commercial interest in TFSC from small investors and large corporations, validating the thin film approach. Unique characteristics are discussed which give TFSC an advantage over c-Si in two specific markets: small rural solar home systems and building integrated photovoltaic installations. TFSC have outperformed c-Si in annual energy production (kWhrs/kW), have demonstrated outdoor durability comparable to c-Si and are being used in MW scale installations worldwide. The merits of the thin film approach cannot be judged on the basis of efficiency alone but must also account for module performance and potential for low cost. TFSC advocates should promote their unique virtues compared to c-Si: lower cost, higher kWhr/kW output, higher battery charging current, attractive visual appearance, flexible substrates, long-term stability comparable to c-Si, and multiple pathways for deposition with room for innovation and evolutionary improvement. There is a huge market for TFSC even at today's efficiency if costs can be reduced. A brief window of opportunity exists for TFSC over the next few years due the Si shortage. The demonstrated capabilities and advantages of TFSC must be proclaimed more persistently to funding decision-makers and customers without minimizing the remaining challenges.

“…Of the thin film cell options, the CuInS2 cells provides superior projected performance and no Staebler-Wronski losses which allows for the smallest feasible PV array size. However, the CuInSz cell design and manufacturing maturity is lower than the competing a-SiGe cell technology that has a strong terrestrial manufacturing base [26].…”

Solar electric propulsion (SEP) mission architectures arc applicable to a wide range of NASA missions including human Mars exploration and robotic exploration of the outcr planets. In this papcr, we discuss the conccptual design and detailed performancc analysis of an SEP stage electric power system (EPS). EPS performance, mass and area predictions are compared for sevcral PV array technologies. Based on these studics, an EPS design for a 1-MW class, Human Mars Mission SEP stage was developed with a reasonable mass, 9.4 metric tons, and fcasible deployed array area, 5800 m2. An EPS was also designed for the Europa Mapper spacecraft and had a mass of 151 kg and a deployed array area of 106 m'.
